Causal Necessity in Kants Empirical Account of Human
Action
In the first Critique, Kant
says, all the actions of a human being are determined in accord with the order
of nature, adding that if we could investigate all the appearances . . .
there would be no human action we could not predict with certainty, and he
gives a striking example to illustrate this general point. He says,
Let us take a voluntary action, for example, a
malicious lie . . . . First of all, we
endeavor to discover the motives to which it has been due, and then, secondly,
we proceed to determine how far the action . . . can be imputed to the offender. As regards the first question, we trace the
empirical character of the action to its sources, finding these in defective
education, bad company, in part also in the viciousness of a natural
disposition insensitive to shame . . . .
We proceed in this enquiry just as we should in ascertaining for a
given natural effect the series of its determining causes. But although we believe the action is thus
determined, we nonetheless blame the agent.[1]
In
the Grounding, he reiterates this: everything which takes place [is]
determined without exception in accordance with laws of nature.[2] And in the second Critique, he
insists that if we knew the relevant preconditions, we could calculate a human
beings conduct for the future with as much certainty as a lunar or solar
eclipse.[3]
At the same time, Kant insists that
human beings are transcendentally free, uncaused causes of their actions: a
rational being can . . . say of every unlawful action he performed that he
could have omitted it.[4] Kants defense of freedom depends on his
transcendental idealism, according to which even though our actions are
determined by natural law, they are nonetheless free. Allen Wood aptly describes this as a compatibility of
compatibilism and incompatibilism,[5]
explaining that while human actions can, on the one hand, be explained by
empirical observation and natural science, and from this standpoint, our
actions are causally determined,[6]
those actions also have a ground that is not capable of being observed, and
that ground may be free.[7]
Kants theory of freedom has important implications
for his empirical psychology. In a
lecture on metaphysics, Kant says,
Freedom cannot be proven psychologically, but rather
morally . . . . If I wanted to prove
freedom psychologically, then I would have to consider a human being . . . as a natural being, and as such he is
not free.[8]
Kant
makes room for human freedom transcendentally, not psychologically, and
thus his psychological account of human action is left thoroughly
deterministic.[9] But while Kants theory of freedom has
received a great deal of attention from contemporary philosophers, his
empirical psychology has not been studied in much detail. There is still a need for a clear
explanation of how Kant thinks human action can be explained from an empirical
perspective.
In this paper, I lay out a clear
description of Kants determinist account of human action, as found in his
empirical psychology. The direct
benefit of this description will be to clear up confusion about the relationship
between empirical and practical accounts of human action by bringing to light
the nature of Kants empirical description of human action. This paper will also be crucial for
developing more historically accurate and philosophically sophisticated Kantian
accounts of the emotions, moral education, cultural and historical influences
on human behavior, and the role of psychology and anthropology in Kants moral
theory.
The need for an explanation of
Kants empirical psychology is particularly important today because many discussions
of Kants psychology focus on Kants account of moral choice from a practical
perspective, and this gives the sense that Kants empirical account of action
depends on what Simon Blackburn calls a Kantian Captain, free of his or her
natural and acquired dispositions.[10] When Andrews Reath, for example, discusses
Kants theory of motivation,[11]
he starts his account with a treatment of respect for the moral law, rather
than a detailed discussion of how non-moral motives function. The result is that presuppositions of Kants
moral theory unduly influence Reaths psychology, so that he insists on finding
freedom within a Kantian account of motivation. Thus he objects that if the moral law
determines choice by exerting a force that is stronger than the alternatives,
moral conduct will result from the balance of whatever psychological forces are
acting on the will . . . . It is not
clear that this model leaves room for any real notion of will or choice.[12] But given Kants transcendental idealism,
such a model does leave room for real choice, not within the
model itself, but from the perspective of practical reason. More importantly, Kants transcendental
idealism, as articulated in the first Critique (especially the Second
Analogy[13]
and the Third Antinomy), shows that it must be possible to give a causal
picture of the kind that Reath opposes.
Similarly, Marcia Baron argues against speaking of
acting from the motive of duty on the grounds that the term motive suggests
causation.[14] She goes on:
This [causal picture of agency] is a familiar picture
of agency from the empiricist tradition. Kants theory of agency is very
different. Our actions are not the
result of a desire or some other incentive that impels us. An incentive can move us to act only if we
let it.[15]
As
evidence for this alternative Kantian picture, Baron appeals to an important
passage in the second Critique in which Kant argues for freedom on the
grounds that one is always conscious of an obligation that ought to and
therefore can be obeyed.[16] Baron is certainly correct, of course, that
for Kant human beings are free and therefore incentives can move only if we let
them. But this account of agency is an
account of transcendental freedom, an account that, for Kant at least, is consistent
with the familiar empiricist picture of agency. There is nothing wrong, of course, with focusing on looking at
agency from the standpoint of freedom.
Kant insists that this is the proper standpoint for moral
philosophy. But by implying that there
is a conflict between the freedom necessary for moral agency and empiricist
accounts of motivation, Baron, like Reath and Blackburn, mistakenly ascribe to
Kants empirical psychology a kind of freedom that Kant thinks is out of
place there.[17]
Including freedom within third-personal descriptions
of human action results in confusion about what Kants causal account of
human action actually is, and this has left room open for critics of Kant such
as Blackburn to accuse Kant of having an overly simplistic account of human
psychology. Blackburns Kantian
Captain is introduced as a prelude to his account of the fundamental mistake
about deliberation that this Captain represents.[18] Blackburn points out that Kants Captain is
just bad psychology. But Kant, like
Blackburn, distinguishes between psychological claims and first personal moral
claims, between speaking from within a moral perspective and describing
those who speak from within it.[19]
And Kants Captain has no place in descriptions of human action, but
only in discussion of what it means to speak from within a moral
perspective. Thus the Captain has no
role in empirical psychology, so it cannot be an example of bad psychology. Unfortunately, simplified accounts of Kants
psychology make it too easy for Blackburn and others to dismiss Kant. And Blackburn rightly claims that Kant, or
perhaps his translators, cannot escape responsibility for the confusion here.[20] Kant bears some responsibility for not
laying out his empirical psychology systematically in any published works. His commentators bear responsibility for
never making use of the published and unpublished resources that Kant did
leave.[21] By drawing on these resources to explain
Kants empirical psychology, this paper will help to clear up some of the
confusion that prompts overly swift dismissals of Kants moral theory.
There are two main aspects of Kants empirical account
of human action. The first is rooted in
Kants engagement with 18th century faculty psychology. In the context of a tradition that describes
the soul as involving appetitive and cognitive faculties, Kant develops an
account of relationships among three main faculties of soul: desire, feeling,
and cognition. This provides Kant with
an opportunity to explain human action as the result of a faculty of desire and
to explore the causes of various kinds of desires. Kants most detailed accounts of this faculty psychology are
found in his lectures on empirical psychology, part of his lectures on
metaphysics.[22] The second aspect of Kants account of human
action comes from his engagement with emerging theories in biology and natural
history and involves Kants account of natural predispositions that underlie
human actions. This second aspect is
necessary to understand both the nature and the limits of Kants causal
accounts. The primary sources for this
aspect of Kants account are taken from his anthropology, including his
historical essays, lectures on anthropology, and his published Anthropology
from a Pragmatic Point of View.
The structure of this paper is as follows: In section
1, I discuss Kants faculty psychology to lay the groundwork for the rest of my
discussion. In sections 2 4, I
explain the predispositions underlying different faculties of soul. This account of predispositions provides a
Kantian account, as far as it goes, of the causal connections between
cognitions and desires. Sections 5 6
complete Kants causal account of action by explaining the causal laws
governing the cognitive faculties. The
result is a complete causal account of human actions, from the experiences that
give rise to them to the actions themselves.
1)
Kants faculty psychology
Kants faculty psychology developed
in response to three main trends in 18th century philosophy: Wolffs
Leibnizian rationalism, Crusiuss Pietist response to Wolff, and British
empiricism.[23] The overall structure of Kants empirical
psychology is largely set by Wolff, who developed a faculty psychology in order
to reduce diverse faculties to representation as the single essence of the
soul. Kants course on metaphysics was
based on the textbook of the Wolffian Alexander Baumgarten, who followed Wolff
in the organization of empirical psychology.
Kant takes over Wolffs and Baumgartens distinctions between different
faculties of soul but resists their attempts to reduce these faculties to a
single essence.
Instead, Kant follows Crusius in resisting this
reduction, and he shifts from a two-fold distinction between cognitive and
appetitive faculties to a threefold distinction between the faculties of
cognition, feeling, and desire.[24] Each of these three faculties includes
several distinct basic powers, none of which is reducible to others. For Kant, the classification of different
basic powers is important because the concept of cause lies in the concept of
power.[25] Different powers reflect different specific
laws of causation. Within the faculty
of cognition, for instance, Kant includes distinct basic powers such as the
five senses, imagination, understanding, and reason, each of which is governed
by its own set of causal laws.[26] Because basic powers are the key to any
causal explanation of phenomena, Kant claims that all physics, of bodies as
well as of minds, the latter of which is called psychology, amounts to this:
deriving diverse powers, which we know only through observations, as much as
possible from basic powers.[27] In both physics and psychology, Kants goal
is to reduce the variety of observable phenomena to as few basic powers as
possible and to explain the laws according to which those powers operate. In psychology in particular, we are to seek
natural laws of the thinking self based on observations about the play of
our thoughts.[28] The result
is a clear and comprehensive causal account of natural phenomena, whether
bodies in physics or minds in psychology.
Finally, from British empiricism Kant adopted the
practice of explaining each power in terms of laws describing regular
connections between phenomena.[29] Unlike many of the British empiricists, Kant
does not focus on laying out causal laws and applying them to understand
various mental phenomena. Kants focus
is on the framework of basic powers for which causal laws will have to be
found. An even more important
difference is that Kant does not think that an empirical account of these basic
powers provides any basis for epistemology or ethics. But when Kant does
describe the laws governing the basic powers, his laws are similar to those of
the empiricists, including a law of association governing the imagination and
various laws of logic and prejudice governing the understanding.[30]
When it comes to explaining human
action, Kant focuses his account on desire: all desires have a relation to
activity and are the causality thereof.[31] Insofar as a representation is the ground of
an action that brings about some state of affairs, it is a desire: the
faculty of the soul for becoming cause of the actuality of the object through
the representation of the object itself = . . . the faculty of desire.[32] An object here is not necessarily a
physical object but anything that can be desired, including physical objects
but also states of affairs.[33]
The object of desire is a possible purpose for an action, and desires, for
Kant, naturally give rise to actions.
As Kant puts it here, a desire is defined as a representation
that leads to action, that becomes cause of the actuality of an object. And when desire is taken in this broad
sense, there are no actions that are not preceded by and caused by desires.
Thus for explaining human action, the most important
task of empirical psychology is tracing the causes of desires. Within this psychology, Kant engages in this
task by connecting the faculty of desire with the other basic faculties of the
soul. For Kant, this relationship is
fairly straightforward:
Pleasure precedes the faculty of desire, and the
cognitive faculty precedes pleasure . . . .
[W]e can desire or abhor nothing which is not based on pleasure or
displeasure. For that which give me no
pleasure, I also do not want. Thus
pleasure or displeasure precedes desire or abhorrence. But still I must first cognize what I
desire, likewise what give me pleasure or displeasure; accordingly, both are
based on the cognitive faculty.[34]
According
to this structure, cognition of an object gives rise (at least sometimes) to a
feeling of pleasure or pain, and that feeling gives rise (again, at least
sometimes) to a desire or aversion for the object. We can trace the series of causes as follows:
Cognition ā Feeling (pleasure or pain) ā Desire ā Action[35]
For
example, one tastes a mango (cognition), that taste gives one pleasure
(feeling), that pleasure causes one to desire the mango, and that desire leads
one to eat (or continue eating) the mango.[36]
Within this picture, feelings of
pleasure and displeasure function as transitions from cognitions to desires
(and thereby to actions). Jeanine
Grenberg has described the connection between these practical pleasures and
desire in detail.[37] As she explains,
[P]ractical pleasure is itself necessarily related to
and is indeed the very vehicle for the expression of the status of an agents
faculty of desire. Technically . . .
there is a distinction to be made between feeling and desire: feeling, an
element of the agents sensible nature . . . determines (bestimmt) the
faculty of desire . . .. For the
purposes of describing action, there is, however, little distinction to be made
between the possession of a practical pleasure and that of a desire.[38]
Like
Grenberg, I will not focus on the distinction between feeling and desire in the
rest of this paper. Given a practical
pleasure, a desire will follow simply because of the nature of practical
pleasures. The challenge for giving a
causal account of human action is to explain the origin of those practical
pleasures.[39]
In this context, the task of giving
a causal account of human action involves two crucial components. First, Kant needs to provide causal laws
governing the connections between cognitions and feelings/desires. This task is complicated because not all
cognitions lead to feelings of pleasure or pain, and not all feelings lead to
desire or aversion. Even within those
cognitions that do affect desire, some lead to desires and others lead
to aversions. Thus Kant needs
some account of why the series goes through in some cases and not others, and
why it leads to the conative state that it does. Second, even if Kant gives a causal account of these connections,
he needs to explain the origins of cognitions.
Since cognitions start the series, as it were, a causal account of
cognitions themselves is required for Kants account of action to be thoroughly
deterministic. Providing these two components
of a causal account of action depends on a more detailed faculty psychology and
a treatment of the role of predispositions in human nature. In the rest of this section, I lay out the
requisite details from Kants faculty psychology. In the next several sections (2 4), I explain the role of
predispositions as causal bases of connections between cognitions and
desires. In the last two sections, I
discuss the causal laws governing cognitions.
In his empirical psychology, Kants approach to both the
origin of cognitions and their connection with desire involves further
distinguishing between different faculties of soul. I have already noted the important distinction between the
faculties of cognition, feeling, and desire, which forms the background for
Kants overall account of human action.
Cutting across this three fold distinction, however, is a further
distinction adopted from Baumgarten between higher and lower faculties
of cognition, feeling, and desire. The
lower faculties are primarily receptive.
The higher faculties are self-active or spontaneous.[40] (In these contexts, Kant generally[41]
uses the terms self-activity or spontaneity to describe an empirical or
comparative freedom of the higher faculties, a freedom that is
consistent with the view that even those higher faculties are causally
determined.[42] When Kant talks about this freedom in the
context of his empirical psychology, it is empirical freedom to which he
refers, and this leaves room for Kant to give a causal account of even the
higher faculty of desire, as we will see in section four.) Thus we can broadly outline six different
faculties in Kants empirical psychology: higher and lower cognition, higher
and lower feeling, and higher and lower desire.
With respect to cognition, the lower faculty is
referred to broadly as sensibility (Sinnlichkeit) and includes the
senses (Sinne) and the imagination, each of which is further subdivided.[43] The senses include the five outer senses as
well as inner sense, and the imagination includes memory, anticipation of
future events, and the productive or fictive imagination. This higher faculty of cognition is often
referred to by the general term understanding (Verstand) and includes
three specific cognitive powers: reason, the understanding (Verstand) in
the narrow sense, and the power of judgment.[44]
Just as there is a higher and a lower cognitive
faculty[,] so there is also a rational and a sensible feeling of pleasure or
displeasure (and so it is also with the faculty of desire).[45] For the present purposes, I focus on Kants
account of the higher and lower faculties of desire, as these are most directly
tied to action, but most of Kants account of higher and lower desire applies
to feeling as well.[46] As with the cognitive faculty, the
distinction between the higher and lower faculties of desire is based on the
distinction between the senses and the understanding: all desires are . . .
[either] intellectual or sensitive.[47] But in the case of desire, what is relevant
is not the nature of the desire itself but the cognitive cause of the
desire.[48] The representations which produce
determinations [of desire] are either sensible or intellectual.[49] Insofar as a desire is the direct result of
the senses or unmediated imagination, is it part of the lower faculty of
desire. Insofar as it proceeds from the
understanding or reason, a desire falls under the higher faculty of
desire. The key difference here is
between motivation by immediate intuitions and motivation by principles or
concepts. As Kant explains, every
desire[50]
has an impelling cause. The impelling causes are either sensitive or intellectual. The sensitive are stimuli <stimuli>
or motive causes [Bewegungsursache], impulses. The intellectual are motives [Motive] or motive
grounds [Bewegungsgrunde] . . . . If the impelling causes are
representations of satisfaction and dissatisfaction which depend on the manner
in which we are [sensibly] affected by objects, then they are stimuli. But if the impelling causes are
representations of satisfaction or dissatisfaction which depend on the manner
in which we cognize the objects through concepts, through the understanding,
then they are motives.[51]
The
distinction between higher and lower faculties of desire is critically
important for Kants overall account of human action because the causal
mechanisms governing desire operate quite differently depending on whether they
belong to the higher or lower faculty.
Though both faculties are determined by impelling causes or
incentives,[52] the higher
faculty is determined by motives which proceed from the understanding and the
lower faculty is determined by stimuli that proceed from the senses.[53] As we will see in sections 3 and 4, the
difference between higher and lower faculties of desire is reflected in
different predispositions that underlie Kants causal accounts of each faculty.
Before moving on to the next section, it is worth
drawing attention to one further distinction within Kants account of the
higher faculty of desire. Higher
desires are caused by one or more kinds of higher cognition, but these desires
need not be purely rational.
Although all higher desires have grounds of determination . . .
[that] lie . . . in the
understanding,[54]
these desires can be either pure or affected.[55] Kant explains this distinction as follows:
The intellectual impelling cause is either purely
intellectual without qualification <simpliciter . . .>, or in some
respect <secundum quid>.
When the impelling cause is represented by the pure
understanding, it is purely intellectual, but if it rests on sensibility, and
if merely the means for arriving at the end are presented by the understanding,
then it is said to be in some respect.[56]
For
a desire to be purely intellectual, it must be caused by the pure
understanding, or pure reason (recall that the understanding in the broad sense
includes reason). But a desire can be
directly caused by higher cognition without being caused by pure reason when
someone acts on the basis of a principle of the understanding that is directed
towards fulfilling some sensible desire (or inclination). Such impure higher desires proceed from
representing to oneself hypothetical imperatives as principles for action. These impure desires are still higher
desires, however, because they are caused not solely by sensible desires but by
principles or concepts of the understanding directed towards satisfying
such desires.[57] The pure higher faculty of desire, because
it involves desires that follow from purely rational considerations, issues
from the representation of categorical imperatives.[58]
We can now summarize the results of
this section by filling in Kants taxonomy of faculties of the soul:
The faculties (and powers)
of the soul
|
Cognition
(representations) |
Feeling
(pleasure and displeasure) |
Desire
(impelling grounds, incentives) |
Higher
(intellectual, active, spontaneous) |
Understanding
(including the distinct powers of judgment, understanding, and reason) |
satisfactions
or dissatisfactions which depend on the manner in which we cognize the
objects through concepts |
Motives,
motive grounds (including both pure and impure motives) |
Lower
(sensible, passive, receptive) |
Sensibility
(including distinct powers of the senses and imagination) |
satisfactions
and dissatisfactions which depend on the manner in which we are [sensibly]
affected by objects[59] |
Stimuli,
motive causes, impulses. |
For
Kant, this taxonomy is the first step in giving causal laws for mental
phenomena because each distinct mental power will be governed by its own causal
laws. (Recall that the concept of cause lies in the concept of power[60]). Thus Kants empirical psychology must
explain the underlying causal mechanisms for the origin of each kind of
cognitive state as well as the mechanisms for connecting those cognitive states
to the states of feeling and desire to which they give rise. The next section offers a crucial further
component of that explanation.
2)
Human predispositions and the limits of mechanist explanation
So far, we have seen that Kant develops his empirical
account of action in the context of a faculty psychology. Kant traces the sources of particular
desires to their connection with other mental states. But Kant also offers a more general account of the bases for
these connections. Human beings desire
some things rather than others, and this is not simply because we cognize some
things rather than others. We often
have cognitions that do not give rise to feelings, and feelings that do not
give rise to desires.[61] To flesh out his naturalistic explanation of
human action, Kant explains why some cognitions but not others give rise to
desires.
As with his psychology in general, Kants approach to
predispositions is empirical and taxonomic.
Kant accounts for human tendencies with his fundamental notion of a
natural predisposition (Naturanlage).[62] He does not give many causal accounts of the
origins of these predispositions. They
are purposive tendencies in human nature that should be classified but cannot
(easily) be explained. As he explains
in his Conjectures on the Beginning of Human History, we must begin with
something that human reason cannot derive from prior natural causes that is,
with the existence of human beings, including all of their natural
predispositions.[63]
In an important respect, the positing of
predispositions reflects a backing off from the implicit commitment of his
first Critique to the possibility of fully mechanistic accounts of human
action. Even Kants faculty psychology
itself reflects a limitation of mechanical explanation, in that Kant avoids the
Wollfian attempt to reduce the powers of the soul to a single kind of power
governed by a single kind of law. In
fact, as early as 1782, Kant makes explicit a kind of scientific modesty when
it comes to mechanistic explanations of phenomena.[64] In a revealing comparison of Descartes and
Newton, Kant distinguishes two modes of study in the physical sciences in a way
that points out the danger of allowing the demand for simplicity to govern
scientific explanation.
There are . . . two physical modes of explanation: (1)
mechanical philosophy, which explains all phenomena from the shape and the
general motive power of bodies
.
(2) The
dynamical mode of explanation, when certain basic powers are assumed from which
the phenomena are derived. This was
first discovered by Newton and is more satisfactory and complete than the
former. Thus to explain something
mechanically means to explain something according to the laws of motion,
dynamically, from the powers of bodies.
With either explanation one never comes to an end. The correct mode of explanation is dynamical
physics, which includes both in itself.
That is the mode of explanation of the present time. The first is the mode of explanation of
Descartes, the second that of the chemists.[65]
Descartes
errs, according to Kant, because he overemphasizes the reduction of phenomenal
explanation to a single power (the general motive power). By contrast, Newton and the chemists rightly
postulate additional basic powers when these are necessary to explain diverse
phenomena. What is more, Kant
highlights here that both kinds of explanation take for granted certain
causal powers, and these are left unexplained.
Kants psychology follows the
example of the chemists rather than mechanist physics. His focus is on not overly reducing
powers to a single basic one. As he
says, for our reason there must be several [basic powers] because we cannot
reduce everything to one.[66] But with respect to psychology, and biology
more generally, Kant develops even more fundamental reasons for questioning the
attempt to reduce all explanations to simple mechanistic ones. Kants modification of his mechanistic
ambitions with respect to human psychology is incorporated into a general
realization that the study of organized beings including humans as well as
birds[67]
and even grass[68] cannot
always proceed mechanically. This
limitation on mechanistic explanation is particularly important in the context
of explaining the origins of organized beings or their specific natural capacities.[69]
In this respect, however, Kant is simply modifying a
dominant strategy of 17th and 18th century mechanists for
dealing with the generation of living beings.
As Phillip Sloan has pointed out, after 1660 . . ., mechanistic
solutions to the problem of organic generation typically involved some version
of preformationism.[70] Preformationism has a strong form, according
to which every living thing was created at the creation of the world and are
simply encased, like Russian dolls[71]
in either ovaries or spermatazoa. The
version with which Kant was more sympathetic early in his career involved
preformed germs (Keime) that unfold into living organisms.[72] Either version, however, retains mechanist
accounts of change within nature while bracketing the problem of finding a
mechanist origin for life itself. Life
itself is simply treated as given, or preformed. The only other mechanist strategy for explaining life was
mechanist epigenesis according to which one gave mechanical explanations
for the emergence of organic structures from inorganic nature. But by the end of the 17th
century, this approach simply looked implausible from a scientific standpoint,
and in the years between the first and third Critiques, Kant came to a
deeper realization of its limits.[73]
Thus in his third Critique, Kant argues against
a purely mechanist account of life. In
a now famous passage, he explains,
It is quite certain that we can never adequately come
to know the organized beings and their internal possibility in accordance with
merely mechanical principles of nature, let alone explain them; and indeed this
is so certain that we can boldly say that it would be absurd for humans even to
make such an attempt or to hope that there may yet arise a Newton who could
make comprehensible even the generation of a blade of grass according to
natural laws that no intention had ordered; rather, we must absolutely deny
this insight to human beings.[74]
Kants
account in the third Critique is not wholly negative, however. Instead, Kant finds a new way to preserve a
commitment to mechanistic accounts of the world in the face of the scientific
obstacles presented by biology.
Although Kant initially was sympathetic with a sort of moderate
preformationism, according to which there are basic germs (Keime) in
nature that develop over time, in the third Critique, he changes his
view in two important respects.[75] First, he shifts from language of germs (Keime)
to the more epigenetic language of predispositions (Anlagen). Unlike germs, which simply unfold into
organic structures, Anlagen are dynamic, purposive predispositions[76]
in the context of which organisms grow and develop. This conception of Anlagen fits well with non-mechanist
conceptions of epigenesis prevalent in the second half of the 18th
century, according to which organisms arise from interactions between various
vital forces. In Blumenbach, for
example, epigenesis involves the evolution of organisms from a basic formative
force (Bildungstrieb). The
emphasis on predispositions rather than germs marks Kants shift towards a
vitalist epigenesis rather than the more mechanist but less explanatory
preformationism. Even this concession
to epigenesis, however, still involves postulating organic structures the
predispositions themselves that fit into a system of generic preformation,
since the productive capacity of the progenitor is still preformed.[77]
The second and more significant change in Kants
biology in the third Critique is that Kants lingering preformationism
is given a status that makes it compatible with a thoroughgoing and mechanist
epigenesis. In the third Critique,
Kants pessimism about finding a Newton . . . of a blade of grass is not a
rejection of the claim that even the generation of a blade of grass must in
fact be causally determined according to natural laws. As Kant insists, the principle that
everything that we assume to belong to nature (phaenomenon) and to be a
product of it must also be able to be conceived as connected with it in
accordance with mechanical laws nonetheless remains in force.[78] And even in scientific inquiry, we have an
obligation to give a mechanical explanation of all products and events in
nature, even the most purposive, as far as our capacity to do so allows.[79] But as a heuristic principle for
researching the particular laws of nature,[80]
one can add to the principle of mechanical causation a principle of final
causes[81]
in order to supplement the inadequacy of [mechanical explanation] in the
empirical search for particular laws of nature.[82] According this heuristic principle, nothing
in [an organized product of nature] is in vain, purposeless, or to be ascribed
to a blind mechanism of nature.[83] By relegating his biology to the status of a
heuristic, a maxim of the reflecting power of judgment[84]
that is merely subjectively valid,[85]
Kant is free to adopt a vitalist epigenesis that explains natural organisms in
terms of purposive structures. This
purposive account can provide relatively satisfying biological explanations
without undermining the fundamental principle that every event in the world in
fact has mechanical causes.[86]
When Kant turns to human predispositions in
particular, he remains faithful to his biological insight that these
predispositions are best explained in terms of how they fit into an overall
system of natural purposes. Throughout
his Anthropology, Kants accounts of various natural powers are
teleological rather than strictly mechanical.
Thus with respect to the natural capacity for dreaming, for example,
Kant says that dreaming seems to be essential: unless dreams always kept the
vital force active during sleep, it would go out, and that illusion by which
someone who is naturally lazy mistakes objects of imagination as real ends
is a means for Nature . . . [to] make us more active and prevent us from
losing the feeling of life.[87]
These teleological explanations of various natural endowments are not strictly
a part of Kants mechanist account of human action. Rather, they reflect a different kind of causal explanation. For the purposes of this paper it is not
necessary to discuss these teleological explanations of human predispositions
in detail. Instead, what is important
is the way natural predispositions, once granted, function in Kants overall
account of the causes of human actions.
Although Kant may not give causal accounts of the origins of
these predispositions, he effectively uses predispositions themselves to ground
causal accounts of particular human actions.
In the next two sections, I show how Kant uses predispositions to
explain the causal connections between cognitions and desires, and thereby to
explain human action.

Human predispositions in Kants theory of action: the lower faculty of desire
Once he allows for the use of predispositions in
explaining the development and behavior of living things, Kant draws on
predispositions to provide the background against which to give his causal
account of human action.
Predispositions fill in the explanation for why certain cognitions lead
to desires, others to aversions, and others to no appetitive response at
all. Thus to explain why the smell of a
particular food gives rise to a desire for it whereas other smells do not give
rise to any desire,[88]
or why certain kinds of social interactions are pleasant and others are not,
Kant appeals to basic predispositions in human nature. A full Kantian account of human action,
then, must classify and give law-like form to the predispositions that underlie
connections between various faculties of soul.
Kant describes basic predispositions in different ways
for each different faculty of the soul.
For our purposes, the most important distinction is between the higher
and lower faculties of desire, since these predispositions are most directly
involved in action. In the rest of this
section, I make use of Kants biology and anthropology to give a fuller account
of the causes of action in the case of the lower faculty. In the next section, I discuss the causes of
action for the higher faculty. Because
the connections between feeling and desire and between desire and action are
relatively straightforward, as noted in section one, I simplify my account and
focus on the connection between cognitions and feelings/desires.
For Kant, predispositions are not simply additional
causes of a mechanical kind. Kant does
not conceive of explanation here as simply adding more motive causes. Rather, he seeks to rigorously explain in
the dynamical mode of Newton, classifying and characterizing the bases for
basic powers of the soul. In this
context, the role of predispositions will not be strictly causal. That is, one does not simply add a predisposition
to a cognition in order to cause a desire, such that
Cognition + predisposition x ā Desire
Rather,
predispositions for Kant play something like the role that gravity plays in
Newtons account, where it is not the case that
Earths mass + Gravity ā falling of apple
That
is, gravity is not just another cause, like the mass of the earth. Instead, gravity is what explains why
the mass of the earth causes the apple fall.[89] I capture this different kind of explanation
with a vertical arrow (↑). Thus
for Newton,
Earths mass
ā falling of apple
↑
Gravity
For
Kant, this is the kind of explanation that will be needed for why certain
cognitions lead to desires and others do not, and predispositions will play a
crucial role in these explanations.
With respect
to the lower faculty of desire, Kant explains the role of natural
predispositions in connecting cognitions and desires terms of instincts,
propensities, and inclinations.[90] The role of instincts in explaining human
action is the most straightforward, so I will start with it. In his Anthropology, Kant explains,
The inner necessitation of the faculty of desire to take possession of
[an] object before one is familiar with it is instinct.[91] In his lectures on anthropology, Kant claims
that instincts are the first impulses according to which a human being acts.[92] Kant is careful to distinguish instincts
from acquired desires, and generally warns against multiplying instincts among
human beings in our explanations of human behavior. Nonetheless, he gives ample examples of instincts throughout his
lectures and published writings, including the sexual instinct, the parental
instinct to provide for young, the sucking instinct of infants, instincts for
various foods, the natural instinct to test [ones] powers, and natural
sympathy, which Kant treats as an instinct.[93]
The clearest example of the way in which instincts
function in causal explanations of human behavior is from Kants short essay,
Conjectural Beginning of Human History, where Kant discusses the role of
instinct in determining which foods the earliest human beings would have
eaten. He says,
Initially, the newcomer must have been guided solely
by instinct, that voice of God that all animals obey. It permitted him to use some things as food
and forbade him to use others. It is
unnecessary, however, to assume for this purpose a particular long-lost
instinct. It could simply have been the
sense of smell and its affinity with the organ of taste, along with the
well-known sympathy between the latter and the digestive organs in other
words an ability . . . to sense in advance whether a given food is suitable for
consumption or not.[94]
In
one respect, Kants treatment of instinct here is atypical, in that he provides
some explanation of the causes of the particular connections between sensing a
particular food and desiring it, through the relationship between smell, taste,
and digestion. With respect to other
instincts, Kant more often makes appeal to particular instincts without
further inclination. But in other
respects, his account here is typical.
A human being has a sensory here olfactory cognition of a particular
food, and this cognition gives rise to a desire because of an instinct for that
particular food. Similarly, Kant
explains in the case of the sexual instinct that as soon as one comes into
society, ones instinct will quickly find an object.[95] In both cases, the appeal to instinct
explains why the mere sensible cognition of food or another person becomes
a desire of a particular kind. Thus one
can expand Kants account of action from section one as follows, at least for
some cases:
Sensory cognition ā Feeling/Desire
↑
Instinct
For
example,
Smell of a ripe mango ā Desire for that mango
↑
Instinct for mangos
In
cases where instinct explains the connection between cognition and desire, the
task of explanation is sufficiently complete when one classifies the different
instincts and describes the laws of their operation. In the context of an account of human instincts, one can causally
explain any desire by appealing to the instinct as a natural predisposition
(here the instinct for mangos) and the activating cause of that instinct (here
the smell of mangos).
While Kant thinks that instincts explain some
human actions, he does not explain most actions in terms of instinct. Even most desires associated with the lower
faculty of desire are not explained by reference to instincts, but by reference
to inclinations. Unlike
instincts, which are relatively few in number, the types of inclination are too
many and too varied to give even a partial list. Inclinations cover a wide range of human desires, from
inclinations for smoking and drinking[96]
to love as an inclination[97]
to inclinations for honor, money, and power.[98] When explaining actions in terms of
inclinations, Kants model is similar to that for instincts. Like instincts, an inclination is a lasting
ground of desire[99] or a
subjective necessity of desiring.[100] Thus for the case of an inclination to
strong drink,[101]
for example, we get:
Sensory cognition
ā Feeling/Desire
(sight or smell of strong drink) (desire to consume the drink)
↑
Inclination
(for strong drink)
Unlike
instincts, however, inclinations are not themselves natural predispositions,
and thus Kants causal story cannot end with this picture. Inclinations are acquired, so for
Kants account to be complete, he needs to explain the causal origin of the
inclination itself.
Kants explanation of the causal
origin of inclinations is fairly straightforward: we acquire inclinations by
past experience, which develops a habitual desire, or more properly a
habitual ground [Grund] of desires.[102] In some cases this relevant past cause of
the inclination need only be a single instance of experiencing the relevant
object of desire.[103] At other times, developing an inclination
depends on frequent repetition[104]
of experiencing the object of inclination.
Thus a more complete account of inclination-based desires (taking drink
as an example again) is as follows:
Sensory cognition ā Feeling/Desire
(sight or smell of strong drink) (desire to consume the drink)
↑
Past
experience with strong drink ā Inclination (for strong drink)
And
now, of course, there is another causal connection between past experiences
of an object and the inclination for that object that needs to be
explained. To explain that connection,
Kant appeals to a different kind of natural predisposition, a propensity (Hang). As Kant explains, Propensity . . . is the
inner possibility of an inclination, i.e. the natural predisposition to the
inclination.[105] A propensity is a subjective possibility
of generating a certain desire,[106]
which can be found even when there is not yet the actual desire.[107] For example, Kant claims that northern
peoples have a propensity to strong drink,[108]
and in the Religion, he clarifies what this means (changing the relevant
people-group!)[109]:
Propensity is actually only the predisposition
to desire an enjoyment which, when the subject has experienced it, arouses
inclination to it. Thus all savages
have a propensity for intoxicants; for although many of them have no
acquaintance at all with intoxication, and hence absolutely no desire for the
things that produce it, let them try these things but once, and there is
aroused in them an almost inextinguishable desire for them.[110]
Inclinations
are not themselves predispositions; rather, they are the result of experiences
of objects for which someone has a propensity.
A northern person who experiences strong drink will develop a habit of
desiring such drink; such a habit is an inclination.
In explaining a particular human action, then, one can
appeal to instincts or inclinations to explain why a particular cognition gives
rise to a desire, whereas another does not.
For the lower faculty of desire, there are two different models for the
causal origin of a desire:
(1)
Sensory cognition ā
Feeling/Desire[111]
(smell of mango) (desire
to eat mango)
↑
Instinct* (for mangos)
(2)
Sensory cognition
ā Feeling/Desire
(sight or smell of strong drink) (desire to consume the drink)
↑
Past
experience (with strong drink) ā Inclination (for strong drink)
↑
Propensity*
(for strong drink)
Again,
the form of this causal account is that sensory cognitions provide the
immediate natural cause of the relevant desires, and instinct or inclination
provides the ground or explanation of why that cause functions in the way that
it does.[112] Instinct and propensity are marked with *s
to indicate that these are natural predispositions for which Kant does not give
a mechanistic explanation (for reasons explained in section two).
4)
Human predispositions in Kants theory of action: the higher faculty of desire
When turning to the higher faculty
of desire, the underlying explanation for the connection between cognitions and
desires is character. Kant uses the
term character in several senses throughout his writings, and it is important
to keep those distinct here. In the
broadest sense, the character of a thing is the law of its causality, without
which it would not be a cause at all, such that every effective cause
must have a character.[113]
In this sense, gravity reflects the character of matter, and ones instincts
are part of the character of ones faculty of desire. In a quite different sense, Kant uses
character, in the context of ones intelligible character, to refer to the
free ground which is not itself appearance of ones appearances in the
world.[114] Character in this sense has no role to play
in any sort of empirical explanation of action. One can not, in particular, empirically explain actions that flow
from the higher faculties of cognition in terms of intelligible character.
The sort of character that plays an important role in
Kants empirical theory of action is distinct from intelligible character and
more specific than the character of an efficient cause in general. Kant refers to this sense of character in
his anthropology as character simply [Character schlechthin], and
defines it as that property of the will by which the subject has tied himself
to certain practical principles.[115] This more specific sense of character plays,
for the higher faculty of desire, the role that instincts and inclinations play
for the lower. In the rest of this
paper, I use character in the narrower sense of Character schlechthin.
Just as instincts and inclinations ground a consistent
connection between the lower faculty of desire and sensuous cognitions, so
character grounds a similar connection with respect to the higher faculty of
desire.
Character is a certain subjective rule of the higher
faculty of desire . . .. Accordingly,
character makes up what is characteristic of the highest faculty of
desire. Each will . . . has its
subjective laws, which constitute . . . its character.[116]
Kant makes the nature of this connection clearer
elsewhere, explaining that the essential characteristic of character . . .
belongs to the firmness of the principles.[117] A person whose actions are explained by
reference to their character is someone whose faculty of desire is determined
by principles flowing from the higher cognitive faculties. The
relevant principles here need not specifically be moral; any principles
can be practical in that they guide action.
As Kant makes clear in his Anthropology, acting on the basis of
firm principles, regardless of the content of those principles, determines
whether or not someone has character:
Simply to have a character relates to that property of
the will by which the subject has tied himself to certain practical principles
. . .. Although these principles may sometimes indeed by false or defective,
nevertheless the formal element of will as such, which is determined to act
according to firm principles (not shifting hither and yon like a swarm of
gnats), has something precious and admirable to it, which is also something
rare.[118]
A
person who acts from any stable set of principles has character. [119] Kant can thus explain the difference between
sensuous people and those with character as follows: the man of principles,
from whom we know for sure what to expect, not from his instinct, for example,
but from his will, has character.[120] Those who act from instinct or inclination
and those who act from character are both predictable we know what to
expect but for different reasons.
Instincts and inclinations ground a regular connection between lower
cognitive states and desires. Character
grounds a regular connection between higher cognitive states principles and
desires.[121]
The picture here looks like this:
Cognition ā Pleasure/Desire
↑
Character
Unfortunately,
the picture as presented here is incomplete because the origin of character
itself is unexplained. Unlike
instincts, which are natural predispositions and thus do not need to be
explained, character comes not from nature, but rather must be acquired.[122] In this respect, character is like
inclination, and like inclination, character depends on both a prior propensity
a propensity to character[123]
and on various influences that cultivate this propensity into character
itself. But whereas Kant gives a fairly
straightforward account of origin of inclinations, he gives no equally simple
account of the origin of character.
This might lead one to think that there is some room for transcendental
freedom in this account of higher desire.
Kant even makes some claims that seem to suggest that character, unlike
inclination, cannot be explained naturalistically. He says, for instance that having character simply characterizes
man as a rational being, one endowed with freedom and that character shows
what man is prepared to make of himself as opposed to what can be made of a
man.[124] Moreover, even if there is some causal
account of character, a complete causal account of human action depends on
giving an account of the higher cognitions themselves. And while a naturalistic explanation of
lower (sensuous) cognitions might seem straightforward, one might question
whether it is possible to give a causal explanation of principles, and
especially of moral principles.
In fact, however, while rationality, the higher faculty of desire, and
character are all associated with freedom, they nonetheless can all be
explained mechanically.[125] In the rest of this section, I take up the
issue of the causal origins of character, and in section 6, I discuss the
causal origins of the higher cognitions upon which someone with character acts.
In
some respects, this mechanical explanation will be similar to that of
inclinations. But Kants account of the
origin of character is much more complex that the account of inclination. For inclinations, Kants causal story is
quite straightforward: Given the propensity to desire a particular kind of
object, one need only experience the object (sometimes multiple times) to
develop the inclination. For character,
the account is not nearly as simple, but this should come as no surprise. Character explains the connections between
highly developed cognitive states and their corresponding desires, and the
capacity for character is one of the features that distinguish human beings
from animals. Thus it is natural that
its causal origin is considerably more complicated than that of inclinations. But this added complexity does not imply
that its origin is not causal.
We
have already seen that the character, like inclinations, is acquired on the
basis of a natural propensity.[126] Just as
someone with a propensity to strong drink may never have an inclination to such
drink, someone with the propensity to character may never develop a
character. But the very need to posit a
propensity to character shows that Kants account of the origin of character
fits within a broader biological account of human behavior in terms of natural
predispositions. In that sense, the
basis of character is no less natural than the basis of inclination.
Kants
account of the factors that contribute to the development of character further
emphasizes its empirical basis. Kant suggests that some human beings are better
prepared for character than others by virtue of other natural predispositions,
such as temperament.[127] Kant says, not every temperament is
inclined to adopt a character, e.g. the melancholy one adopts a character
first, the sanguine one not so easily,[128]
and of one with a phlegmatic temperament, Kant claims, without being
brilliant, he will still proceed from principles [and hence from character] and
not from instinct.[129] Kants discussion of temperaments is
psychological and empirical, and temperaments can even be influenced . . .
by the physical condition of a person.[130] Insofar as temperament plays a role in the
formation of character, this formation is at least influenced by natural
causes.
Kant
discusses further aids to the cultivation of character that are not natural
endowments but are nonetheless empirical causes. Among these education is the most important.[131] The acquisition
of good character with people happens through education.[132] And even when Kant is most insistent that
the act of establishing character is absolute unity of the inner principle of
our conduct and thus a kind of rebirth, he points out that education,
examples, and instruction . . . produce this firmness in our principles.[133] The transformation[134]
whereby ones character is established is something that is produced (bewirkt)
by education.
Kants
accounts of character are often accompanied by specific pedagogical
recommendations. He suggests that
because imitation . . . greatly hinders character, in education one must never
refer ones children to the neighbors children, . . . but rather build their
character directly, [using] principles of good and bad to inspire righteousness
and nobility.[135] Particular details about the kind of
education someone receives can influence whether that education leads to true
character or mere imitation. And in the
Critique of Practical Reason, Kant even discusses the way one can
cultivate not just character, but good character, in a ten-year-old boy. One can bring this boy to admiration, and
even the endeavor to resemble a virtuous person.[136] The key to this education, for Kant, is to
focus on the purity of the moral law.
And Kants discussion of education here shows that repeated arguments
against heteronomous accounts of the nature of morals have an important pedagogical
purpose. As he explains, every
admixture of incentives taken from ones own happiness is a hindrance to
providing the moral law with influence on the human heart.[137] Kants claim here might seem to be an
indictment of appealing to empirical causes in explaining moral action. But his point is really that certain kinds
of empirical causes instructions that appeal to happiness are ineffective.[138] The empirical influence that actually can
give the moral law influence over a persons heart is a story[139]
within which the moral law is described in its purity. Likewise in the Metaphysics of Morals,
Kant gives a fragment of a moral catechism as an example of how to teach
virtue to children, and even offers an outline of the experimental (technical)
means for cultivating virtue.[140] Character in general, and good character in
particular, cannot be cultivated in the same simple ways that inclinations can
be cultivated. Kants focus on the
details of good character education show how challenging such education
is. But this attention to education in
the development of character makes sense only because character is something
produced by the right kind of education.[141]
Education
is the most important influence on character, but Kant also mentions other
empirical influences. Politeness plays
an important role in the cultivation of character by combating passions and
promoting self-control.[142] In his writings on history and politics,
Kant gives further explanations for how natural inclinations can give rise to
various social institutions including stable and just political regimes,
peace, and even progress in the arts and sciences that may have beneficial
effects on character.[143] Thus experience and history provide
reasons that we should not despair about our species progress toward the
better.[144] The increasing presence of stable political
structures and advancing culture, like the presence of stable norms of polite
society, can help the cultivation of constancy in principled action. These external influences, like the more
direct influence of education, help to produce character.[145]
Filling
in Kants overall account of character, one gets:
The account in
the case of higher desires is considerably more complicated than in the case of
lower desires (whether those lower desires are explained by inclinations or
instincts), but a more complex causal account is still a causal account. Because all actions are caused by either
higher or lower desires, Kant has provided, at least in outline, a causal
account of the connections between cognition and desire for all human
actions. All that remains to have a complete
causal account is an explanation of the origin of cognitions themselves. In the next two sections, we turn to that
task.
5)
Causal accounts of cognition: the lower faculties of cognition
In his empirical psychology and
anthropology, Kant distinguishes between the higher and lower faculty of desire
on the basis of the causal origin of desires.
Insofar as desires are caused by higher cognitions concepts or
principles those desires are ascribed to the higher faculty of desire and the
connection between cognition and desire is explained by reference to
character. Insofar as desires are
caused by lower cognitions sensations or imaginings those desires are lower
desires and the connection between cognition and desire is explained by
reference to instincts or inclinations.
In both cases, a fully causal account of human action must not only
explain the connections between cognitions and desires but must also give a
causal account of the origin of the cognitions themselves. In this section I argue that Kant is
committed to the possibility of such a causal account of cognitions (at least
in principle), and I give some details about the nature of that causal account
in Kant. As in the previous section, I
divide my discussion here according to the higher and lower faculties, and I
discuss the lower faculty (of cognition) first.
In Kants lectures on empirical
psychology, his accounts of the faculties of cognition are generally brief, and
Kant sometimes refers explicitly to his anthropology for further information
about the nature of cognitive powers.
Thus in a late (probably 1790-1) lecture on empirical psychology, Kant
briefly discusses the cognitive faculty, but adds that anthropology will treat
of this in more detail.[146] Unfortunately, although Kants pragmatic
anthropology and related lectures on anthropology give more detail about these
faculties, they do so in a particular context.
Kants pragmatic anthropology presents causal accounts not simply for
the sake of information but in order to put to use those causal accounts
of ones faculties. In the introduction
to his published Anthropology, Kant explains this difference between
speculative theorizing and pragmatic anthropology:
If we ponder natural causes for example, the
possible natural causes behind the power of memory we can speculate to and
fro (as Descartes did) about traces, remaining in the brain, of impressions
left by sensation we have experience.
But since we do not know the cerebral nerves and fibers or understand
how to use them for our purposes, we still have to admit that we are mere
spectators at this play of our ideas and let nature have its way. So theoretical speculation on the subject is
a sheer waste of time. But when we
use our observations about what has been found to hinder or stimulate memory in
order to increase its scope or efficiency, and need knowledge of man for this
purpose, this is part of anthropology for pragmatic purposes; and that
is precisely what concerns us here.[147]
For
Kant, both pragmatic anthropology and theoretical speculation lay out various
natural causes of mental faculties. The
difference is that pragmatic anthropology focuses on causes that it can use
to improve those faculties.
In that context, Kants causal
accounts of the nature and function of the cognitive powers is focused on two
important tasks. First, Kant lays out
causal laws that govern the normal and healthy functioning of the cognitive
powers. Second, he describes ways that
these cognitive powers can be improved, focusing in particular on various problems
or defects that can arise with respect to ones cognitive powers and
how (if at all) these can be treated or prevented.
The lower faculty of cognition
involves the senses and the imagination, and Kant explains various causal laws
governing the behavior of both. With
respect to the senses, Kant is brief.
Unlike Hume, however, who simply argues that impressions . . . of
sensation . . . arise in the soul originally, from unknown causes,[148]
Kant at least offers some explanation of the origin of sensory ideas.[149] He says, for instance, that the sense of
touch lies in the fingertips and the nerve endings (papillae) and enables us to
discover the form of a solid body by means of contact with its surface and
that sight is a sense of indirect perception appearing to a certain organ (the
eyes) sensitive to agitated matter, namely light, which . . . is an emanation
by which the locus of an object in space is determined.[150] Kant gives similar accounts of hearing,
smell, and taste. The general accounts
of purely sensory cognitions involve mechanical interactions between objects
and sensory organs. The connection
between these mechanical interactions and the corresponding sensory cognitions
is simply posited in the way that basic powers are. Thus Kant explains that Nature seems to have endowed man . . .
with this organ [of touch]. The organs
are the basic powers of sensory cognitions, and they are not further explained
mechanically in Kants account.
In addition to the senses, the lower
cognitive faculty includes the imagination.[151] Kants account of the imagination is similar
to that of the empiricists. Imaginative
cognitions begin with sensory cognitions, and they can never go beyond what has
been made available by the senses. Kant
explains that even the productive [produktive] [imagination] is
nevertheless not creative [schöpferisch], because it does not
have the power to bring forth a sensory representation that was never given to
our sensory powers.[152] Moreover, Kant follows the empiricists in
positing a law of association of ideas[153]
as the fundamental law governing the relations between ideas of the
imagination, and he gives several varieties of this principle to explain
different ways in which one idea can lead to another. For example, in a passage that could almost be taken straight
from Hume, Kant explains how empirical ideas that have often followed each
other produce a mental habit such that, when one is produced, this causes the
other to arise as well.[154]
With respect to both the senses and
the imagination, Kants basic account of the causal laws governing their
operation covers the operation of normal or healthy senses and
imagination. But in both cases, Kants
attention to the well-functioning senses and imagination is sparse relative to
his treatment of various influences that can change usually in ways that are
unhealthy the normal functioning of these faculties. Thus with respect to the senses, Kant
devotes a section of his published Anthropology to the inhibition,
weakening, and total loss of the sense powers through such causes as
drunkenness and fainting.[155] And with respect to the imagination, Kant
discusses the ways in which intoxicating food or drink[156]
can influence the imagination, he lists some faults of the imagination,[157]
and he describes various standard ways in which the imagination can lead one
astray. For instance,
When one reads or hears of the life and deeds of a man
who is great by virtue of his talent . . ., one is generally misled in
ascribing considerable stature to him in imagination . . .. Not only the peasant, but even someone
fairly well acquainted with the ways of the world, feels strange when the hero,
who appearance had been judged by the deeds sung of him, presents himself as a
little fellow, and when the sensitive and gentle Hume presents himself as a
square-built fellow.[158]
This
focus on disorders, and ways of correcting them, is what one would expect from
Kants pragmatic anthropology. And
Kants approach is no less causal for this practical focus. The result is an account of causal laws
according to which Kant briefly explains the normal functioning faculties of
sense and imagination and then discusses various ways of causally influencing these
faculties for better or worse.
Given his account of the causal
origins of lower cognitions, we can now complete Kants overall account of the
lower faculty of desire.[159] Interactions between sense organs and the
physical world give rise to sensory cognitions in accordance with natural laws
governing the operation of sense organs.
These sensory cognitions can cause desires in accordance with ones
instincts or inclinations, or they can give rise to further lower cognitions
(of imagination) according to various laws of association. If they give rise to imaginative cognitions,
these can in turn give rise to desires in accordance with instincts or
inclinations. And these desires can
cause actions, either directly or by affecting higher practical principles.
6)
Causal accounts of cognition: the higher faculties of cognition
One might think that even if Kant
can give a causal account of the lower faculty of cognition the
cognitive faculty that is supposed to be primarily passive or receptive
he will not be able to give a similar account for the spontaneous or
self-active higher faculty.[160] However, although the accounts of the higher
cognitive faculties are in some respects more complicated than those of the
lower faculties, Kant does not think that higher cognitive faculties are any
less natural, nor any less susceptible to explanation in terms of natural
causes, than the lower faculties.
Kant
identifies all the basic powers of the soul as natural predispositions,[161]
and understanding and reason, the characteristic powers of the higher
cognitive faculty, are specifically identified in this way.[162] Even pure concepts can be traced to
predispositions in the human understanding,[163]
and the three sorts of practical reasoning technical, pragmatic, and
moral are labeled predispositions.[164] In the Metaphysics of Morals, Kant
even explicitly includes powers . . . whose . . . use is not drawn from
experience but rather derived a priori from principles, along with memory,
imagination, and the like among the natural predispositions that one has a
duty to perfect.[165] However reason and the understanding appear
from within the context of epistemology and pure moral philosophy, when
considered within the context of anthropology and empirical psychology, they
are simply natural predispositions.
Like
other natural predispositions, the higher cognitive powers are in a sense left
unexplained.[166] Kant gives various teleological explanations
for why human beings have these predispositions,[167]
and he even offers some conjectures about the causal origins of human
reasoning.[168] But Kant generally treats the higher
cognitive faculty just like any other natural predisposition, as something
which is itself left unexplained, a properly basic power. Just as in the case of other
predispositions, however, Kant insist that there are characteristic laws that
govern the connections between cognitions within the higher faculty of
cognition. Kant says in the first Critique,
for example, that even . . . reason . . . must exhibit an empirical character
and suggests that reason is itself determined by further influences.[169] In his lectures on ethics, Kant is adamant
about this further determination of reason:
Even ones reason, as subjected to the laws of nature,
can be considered devoid of all freedom . . . . Man is not set free from the mechanism of nature by the fact that
in his action he employs an actus of reason. Every act of thought or reflection is itself an occurrence in
nature . . . though this actus is an inner occurrence, since it takes
place in the man himself . . . . So the fact that a man is determined to action
on grounds of reason and understanding does not yet release him from all
mechanism of nature.[170]
At least in general terms, Kant reiterates his claim
that all mental phenomena are causally determined, even those that are
rooted in the spontaneous higher faculties.
Just as lower cognitions are caused either directly or
indirectly by experience, Kant insists that higher cognitions are also caused
by experience. In the first Critique,
Kant explains this point in a way that highlights the difference between the
empirical cause of a higher cognition and its epistemic justification.
There is no doubt whatever that all our cognition
begins with experience. . . . As far as time is concerned . . . no
cognition in us precedes experience, and with experience every cognition
begins.[171]
Kant makes this claim precisely in the context of
distinguishing a priori cognitions, the most pure of the cognitions
associated with the higher faculty of desire, from empirical ones. As Kant makes clear here, although all our
cognition commences with experience, yet it does not all on that account
arise from experience, and in that sense that there might well be
cognition independent of experience.[172] The point here is that even if all
cognitions are empirically caused, they need not be empirically justified.[173] In terms of empirical psychology, one can
find a cause for any cognition, and that cause will always be an experience of
some kind. But this does not mean that
the content of the cognition is limited by the experience that causes it, nor
that it is justified by that experience.
When
it comes to actually stating the causal laws that govern the higher faculties
of cognition, Kant follows the trend established with the lower faculties,
briefly discussing the normal operation of the understanding, judgment, and
reason, but focusing on various ways in which these faculties can have
defects or illnesses. Like his
accounts of the senses and unlike his account of the imagination, Kants
discussion of the laws governing the normal functioning of the higher faculties
is very brief in his anthropology (both published and lectures) and lectures on
empirical psychology. Unlike the
senses, however, where one needs to look to biological accounts of sense organs
for more detail about proper function, Kant provides details about the proper
functioning of the higher faculties of cognition in his Kants logic.
It
might seem out of place to look for causal laws in Kants logic. In his lectures on logic, Kant explicitly
distinguishes the study of the mind involved in logic from that of
psychology. He explains,
Some logicians, to be sure, do presuppose psychological
principles in logic. But to bring such
principles into logic is just as absurd as to derive morals from life. If we were to take principles from
psychology, i.e. from observations concerning our understanding, we would
merely see how thinking does take place and how it is under
various subjective obstacles and conditions; this would lead then to cognition
of merely contingent laws. In
logic, however, the question is not about contingent but about necessary
rules; not how we do think, but how we ought to think.[174]
As
Kant makes clear here, the laws of logic are necessary laws, not derived from
observation, and hence distinct from the psychological laws that actually
govern the connections between higher cognitions. At the same time, however, Kant claims in his logic that like
all our other powers, the understanding in particular is bound in
its actions to rules, which we can investigate.[175] Kant even compares this law-likeness to
everything in nature, [which] takes place according to rules, such
that water falls according to laws of gravity and with animals locomotion also
takes place according to rules.[176] Thus on the one hand Kant claims that
psychological rules governing the understanding are distinct from logical ones,
but on the other he claims that his logic investigates rules that are like
those of other natural laws.
This apparent conflict can be resolved
by keeping in mind two important details in Kants distinction between logic
and psychology. First, Kants
separation of the two is unidirectional.
Kant specifically warns against using psychological generalizations in
logic, not about using logical laws as guides in empirical
psychology. Second, Kants account of
how the mind actually works is not simply a matter of logic. Logic describes how the understanding ought
to operate, and this will describe how the understanding in fact
operates only if the understanding is functioning properly. Often the understanding does function
properly, and in those cases, Kants logic provides an account of the
psychological laws governing the connections between higher cognitions. But human minds are also susceptible to
subjective obstacles and conditions,[177]
some of which are quite common. A
complete causal account of higher cognition would have to explain the ways in
which these subjective obstacles interfere with proper functioning of the
understanding. In his logic,
psychology, and anthropology, one finds descriptions of these variations from
normal function. Such descriptions
represent an important tangent when discussed in Kants lectures on logic, but
in his anthropology, these variations and various ways to treat or prevent them
are a proper focus of Kants attention.
By structuring his overall account of mental operations in this way,
Kant can apply the insights of his logic to flesh out his empirical description
of human action without conflating logic and psychology.
It should not be too surprising that
Kant analyzes the causal laws governing the higher faculty of cognition by
reference to logic, the rules governing its proper function, and focuses in his
anthropology on deficiencies and diseases of the soul with respect to its
cognitive powers.[178] Even in his accounts of the senses, Kants
focus is on the inhibition, weakening, and loss of the sense powers,[179]
rather than the causal laws governing their normal operation. And in his lectures on logic, although Kant
insists that logic must be distinct from psychology, he consistently gives at
least some attention to ways in which the actual operation of the
understanding differs from how it ought to conduct itself. Thus he asks, for instance, How is it
possible for a power to depart from its own laws? and even claims that the
understanding itself cannot err,[180]
suggesting that the laws governing the actual conduct of the
understanding are just those that govern the way it ought to be, at
least in the absence of influences external to the causal laws governing the
understanding itself.
Moreover, even the most ardent
empiricist accounts of mind (at least in the 18th century) turn to
apparently logical laws when explaining the operation of healthy higher
cognitive faculties.[181] When Hume sets out to determine the faculty
responsible for the transition from an impression present to the memory or
sense to the idea of an object, which we call cause or effect, he asks
Whether experience produces the idea by means of the understanding or of the
imagination; whether we are determined by reason to make the transition, or by
a certain association and relation of perceptions.[182] To determine whether or not reason is the
faculty responsible for this transition, he appeals to a principle that, in
accordance with basic laws of deductive logic, would justify this
transition. Hume uses the apparently logical
claim that the transition is not deductively justified to justify the psychological
claim that the cognitive faculty responsible for the transition is not the
understanding (or reason). In this context,
Hume treats the laws of logic as the causal laws governing the operation of
reason. In appealing to logic as a
source of causal laws of a properly functioning understanding, Kants account
is no less causal-determinist than Humes.[183] And in explaining various ways in which the
higher faculties can fall short of proper function, Kants causal account is
actually more sophisticated than Humes.[184]
Kants causal account of the healthy understanding is
fairly ordinary, rooted in his broadly Aristotelian account of logic. As in the case of the lower faculty, there
are different laws governing different specific powers of cognition. Thus the understanding in a narrow sense is
governed by laws regarding the formation of concepts and judgments and laws
governing connections between various judgments.[185] With respect to connections between
judgments, for example, Kant distinguishes between immediate and mediate
inferences, where the inferences of the understanding, properly speaking, are
all immediate and include such inference-types as the universal rules of
conversion, such as the inference from all men are mortal to some of those
who are contained under the concept mortal are men.[186]
With respect to the formation of concepts, Kant claims
that there are three logical actus of the understanding, through which
concept are generated . . .: 1. comparison . . ., 2. reflection . . ., [and] 3.
abstraction. Kant gives the following
example:
I see, e.g., a spruce, a willow, and a linden. By first comparing these objects with one
another I note that they are different from one another in regard to the trunk,
the branches, the leaves, etc.; but next I reflect on that which they have in
common among themselves, trunk, branches, and leaves themselves, and I abstract
from the quantity, the figure, etc. of these; and thus I acquire a concept of a
tree. [187]
This
account of concept formation is not specifically designed as a causal account,
but as a normative logical one. Kants
point here is not an empirical generalization about how people in fact arrive
at concepts, but about how one should acquire concepts. But the account also functions as Kants
explanation of how a properly functioning understanding can acquire new
concepts.
While comparison, reflection, and abstraction feature
prominently in Kants logical account of how one should acquire
concepts, they are not the only way that one in fact acquires concepts. In fact, concept acquisition through instruction
is an area in which Kants anthropology contributes significantly to understanding
the normal functioning of the understanding.
One can acquire concepts from other people through instruction, and this
source of concepts is is prominent in Kants anthropology. As he explains, Instruction can enrich
natural understanding with many concepts and equip it with rules.[188] In his lectures on pedagogy, Kant discusses
the cultivation of the mind[189]
and in particular the cultivation of the higher faculties of cognition.[190] For example, the understanding may at first
be cultivated . . . by quoting examples that prove the rules, or . . . by
discovering rules for particular cases.[191] Kant breaks down the factors involved in
education in his Anthropology, pointing out in particular the role of
language.[192] Kant gets into even more detail about the
causal nature of this communication by connecting the transmission of concepts
specifically with physical causes that influence ones sense organs: it
is by this medium [air], when it is put into motion by the vocal organ, the
mouth, that we can most readily and fully share in one anothers thoughts . . .
. [W]ords are the means best adapted to
signifying concepts.[193]
Kants commitment to this causal basis for the
development of the understanding goes so far, in fact, that he makes hasty and
unfortunate claims about those who lack the sensory capacities for hearing: a
man who, because he was deaf from birth, must also remain dumb (without speech)
can never achieve more than an analogue of reason and a man born deaf
. . . does [nothing] more than carry on a play of . . . feelings, without
really having and thinking concepts.[194] Kants point here is clearly overdone, and
one would hope that more experience with the deaf, or even just more
thoughtfulness, would have corrected his opinion. The deaf are more than capable of thinking with concepts and have
more than an analogue of reason. But
Kants conviction that they would be impaired in the higher cognitive faculties
because of a hindrance in sense organs shows his commitment to a causal
explanation of concepts rooted in the senses, even while he maintains an
epistemic position that some of these concepts are a priori.
In his anthropology, and even to
some degree in his logic, Kant goes beyond a description of the way that the
higher cognitive faculty ought to proceed and discusses some of the ways
in which its operation differs from this normative standard. This practice of giving a normative account
supplemented by various disorders is consistent with Kants practice throughout
his anthropology, including his treatment of the lower cognitive faculty and
even the faculties of feeling and desire.[195]
When Kant turns to non-normative accounts of cognition
in his logic, he focuses on the role of prejudices in causing the higher
faculty of cognition to operate in a way that is different from the standards
of logical perfection. Prejudices, in
general, are provisional judgments . . . accepted as principles,[196]
and they affect the way in which other cognitions arise. In that sense, they play a causal role in
ones higher cognitions. For example,
the prejudice of the prestige of the age leads us to favor the writers of
antiquity more than we should, thereby elevating the relative worth of their
writings to an absolute worth.[197] This prejudice leads people to adopt
principles that they otherwise would not adopt, simply because they read of
those principles in the ancients. Not
only do prejudices themselves play a causal role in Kants account of the
understanding, he explicitly seeks the causes [Ursache] by which
. . . prejudice . . . is created and sustained,[198]
and he finds that there are three principle sources of prejudices . . .:
imitation, custom, and inclination,[199] all of which are empirical influences on
higher cognitions. Thus even in his
logic, Kant gives empirical-causal explanations of the factors that play a role
in bringing the understanding to operate in non-normative ways.
In the Anthropology, Kant focuses less on
common prejudices and more on uncommon weaknesses and illnesses [Schwächen
und Krankheiten] affecting the cognitive powers, as well as various
talents that are relevant to cognitive faculties. This focus is in keeping both with the popular approach of Kants
anthropology, wherein he seeks to present phenomena and their laws in a way
that is entertaining and never dry,[200]
and with the connection between his anthropology and 18th century
natural history. With respect to the
former, the focus on disorders of these kinds, rather than fallacies of
prejudice, give Kant the opportunity to present numerous colorful examples of
mental weakness and disorder, which his students would have found entertaining
and could compare with their . . . experience.[201] With respect to the latter, the focus on
weaknesses, illnesses, and talents brings Kants discussion of the higher
cognitive faculties in line with his more general anthropological approach,
where he focuses on natural endowments and quasi-biological classification of
different types of people.
In keeping with his anthropology and empirical
psychology more generally, Kants approach to these disorders is more taxonomic
that strictly causal. He distinguishes
mental weaknesses, where someones reason simply has not enough control over
itself to direct thoughts, from mental illness, wherein someones stream of
thoughts follows its own (subjective) rule, which is contrary to that
(objective) [rule] that conforms to the laws of experience.[202] Mental deficiencies include being dull,
simple, or silly, lacking judgment, and distraction. The differences between these deficiencies depend on which
cognitive faculty is affected (reason, the understanding, or the power of
judgment) and in what ways that faculty fails to function properly. In each case Kant explains ways in which
these deficiencies affect ones cognitive function, and in each case the
taxonomy marks different causal stories of the flow of cognitions. For example, someone who is dull lacks
intelligence, the faculty for discovering the universal for the particular;[203]
thus such a person cannot effectively acquire concepts for him or herself
through the process of comparison, reflection, and abstraction. Such a person can still be taught, however. So, for example, Clavius, whose
schoolmaster wanted to apprentice him to a blacksmith because he could not make
verses [showing that he was dull] . . . . became a great mathematician as soon
as he got hold of a book of mathematics.[204]
With mental illnesses, Kants approach is
similar. He distinguishes melancholia
(hypochondria) and mania. The former
can cause an illness because human nature, by virtue of a peculiar quality
lacking in animals, can strengthen or sustain a feeling by centering attention
on certain local impressions.[205] Thus one focuses on certain sensations and
conjures up imagined illnesses, which can eventually dominate ones life,
making one unable to come to grips with his imaginings.[206] With respect to the latter, Kant pessimistically
claims, It is difficult to bring systematic classification to what is
essential and incurable disorder.[207] Mania covers such a wide variety of
divergent and irregular mental illnesses that Kant despairs of providing an
exhaustive catalog of them. Moreover,
in the context of his pragmatic anthropology in particular, it is of little
use to occupy oneself with [mania] because all methods of cure must be
fruitless . . .. Still, anthropology
requires at least an attempt at a general outline of this most profound
degradation of humanity which seems to originate from Nature.[208] In this context, Kant distinguishes between
several different kinds of derangement, focusing on broad classifications
rather than specific varieties of each.
1. Madness [Unsinnigkeit;
amentia[209]] is the
inability to bring ideas into mere coherence necessary for the possibility of
experience . . ..
2. Dementia [Wahnsinn;
dementia] is that disturbance of mind wherein everything which the insane
person relates is in accord with the possibility of experience, and indeed with
the formal laws of thought; but because of falsely inventive imagination,
self-concocted representations are treated as if they were perceptions . . ..
3. Insanity [Wahnwitz;
insania] is disordered faculty of judgment in which the mind is deceived by
analogies, which are being confused with concepts of similar things . . ..
4. Lunacy [Aberwitz;
vesania] is the sickness of a disordered reason. The patient disregards all the facts of experience and aspires to
principles which can be entirely exempted from the test of experience . . .. This fourth kind of madness could be called
systematic. For in this last kind of
mental derangement there is not merely lack of order and deviation from the
rule for the use of reason, but also positive unreason; that is, another
rule is present.[210]
In
each case, the relevant higher power of cognition understanding for the first
two, judgment for the third, and reason for the last fails to operate
according its normal rules of operation, operating either in essential
disorder, according to causes that cannot be easily subsumed under rules, or
according to another rule that that which is normative for the respect
faculty, as in the case of positive unreason.
For a complete causal account of the higher cognitive
faculties, Kant should give causal accounts of the origins of these mental
illnesses, or should show that they are natural predispositions in those who
have them. With respect to derangement,
Kant focuses on biological bases, arguing that the germ [Keime] of
derangement develops together with the germ of reproduction, and is thus
hereditary.[211] Kants idea here seems to be that such
derangement simply sets on at a particular time due to biological factors. The definite object that becomes the
subject matter about which the person will rave is based on an accidental
encounter; this object is simply what first comes into the mind at the
(usually sudden) outbreak of a crazy disposition.[212] With respect to other mental illnesses, Kant
gives a bit more detail about contingent causal factors relevant to their
genesis. He claims, for example, that
the reading of novels can cause many . . . mental discords and has the
consequence that it makes distraction habitual.[213] The failure to give sufficient details about
the biological and contextual causes of various mental disorders is a
limitation to Kants empirical account of human action. But this limitation is understandable in a
philosopher whose primary focus was on normative rather than psychological
issues, and the scarcity of detail here hardly compromises Kants overall
commitment to causal necessity in human action.
Overall, then, Kants empirical account of the higher
faculty of desire can be explained causally in a way similar to that for the
lower faculty of desire. The causal
account of the higher faculty of desire begins with higher cognitions. One gets these principles of the
understanding either through a process of comparison, reflection, and abstraction
that begins with sensory experience, or through education, including such
informal education as conversation in which someone introduces another to a
new concept or principle. Some of these
principles of the understanding are practical, in that they give rise to
desires in accordance with ones character.
And that character is itself the result of various empirical influences
acting in the context of a natural predisposition, a propensity for character.
7)
Conclusion
Whether actions proceed from the
higher or the lower faculty of desire, Kants empirical account of these
actions is determinist.[214] It is based on his classification of the
human faculties into the faculties of cognition, feeling, and desire. Every action follows immediately from a
desire. Desires themselves are the
result of particular kinds of pleasures following from particular kinds of
cognition. And desires can be caused by
a variety of types of cognition, from raw sense-perceptions as when a
delicious smell draws us to eat food to principles of reason. The causal origin of all of these
cognitions, however, can be traced back to sensory experiences, either
immediately (for sensory cognitions) or indirectly through laws of association
(for the imagination), rules governing comparison, reflection, and abstraction
(for the understanding), or
principles of linguistic communication and instruction (also for the
understanding). Whether a particular
cognition will give rise to a desire (and thereby an action) depends on ones
natural predispositions and the ways that these have been cultivated to
generate the inclinations and character that one has. The biological structures in human beings provide the foundation
for any particular explanation of behavior in empirical psychology. And every such explanation will be
thoroughly deterministic, accounting for action on the basis of desires that
are caused by ones nature, background, and circumstances.
There is more detail that could be added to this
account. I have not, for instance,
shown how some of the familiar terms of Kantian psychology such as interests,
maxims, choices, or the will fit into the account I have presented here. There is also considerably more that could
be said about the specific laws governing instincts, inclinations, and
particular features of character. One
might explore what preconditions are necessary to develop each particular
inclination that one finds in human beings, what limits there are to the scope
of principles that can form the basis of character, or what causes various
mental illnesses. Kants detailed
pedagogical insights could be expanded into a fuller account of the ways in
which both cognitive and character development take place in human beings. Kants accounts of inclination, instinct,
character, feeling, and desire could be compared with recent psychological and
philosophical work on the emotions.
Kants account of feeling in particular was not analyzed in detail, and
there are subtleties in that account that I have not discussed.
Finally, it would be well worth applying the
psychology laid out here specifically to the context of actions motivated by
respect for the moral law. Respect
functions as the intellectual (higher) feeling that causes one to act morally,
and it is in turn caused by a cognition of the moral law itself. But there are notorious difficulties with
making sense of this account, and the psychology that I have presented provides
a framework within which to make sense of respect. In the context of discussing moral action in particular, there
may seem to be specific obstacles to giving a complete causal account, and some
specific discussion of Kants causal accounts of moral action would be valuable
further fruit of this study of his psychology.
My goal in this paper, however, was
simply to lay out Kants overall empirical psychology. I argued that this psychology is thoroughly
determinist, at least as much as any other causal accounts in biology. I have shown that in his empirical
psychology, Kants account of human beings is precisely the opposite of the
popular interpretation of Kant that Blackburn captures well with his account of
a Kantian Captain who is immune in all important respects from the gifts or
burdens of our internal animal natures, or of our temperaments as they are
formed by contingent nature, socialization, and external surrounds[,] . . . .
free of his or her natural and acquired dispositions.[215]
In this paper, I have given at least some sense of how Kants empirical
psychology describes those features in our animal natures that, combined with
socialization and external surrounds of particular kinds, give rise to the
natural and acquired dispositions that explain human action. This empirical dimension of Kants account
of human action provides a needed and under-appreciated complement to the
accounts of human action from the standpoint of practical reasoning, accounts which
properly emphasize human freedom. By
adding this dimension, important interpretive problems in Kant can be discussed
in more psychologically astute ways, and Kants philosophy as a whole cannot be
as easily dismissed on the grounds of its supposed psychological naiveté.[216]
[1] The first
passage is from A549/B577. The example
is from A554-55/B 582-83, with emphasis added.
Kant reiterates this point with a very similar example in a set of lectures in 1794-5 (29:1019-20), suggesting that the point is not limited to Kants early Critical writings.
(Throughout this paper, reference to Kant are to the Academy Edition of Kants works or to the standard A and B editions of the Critique of Pure Reason. For English translations, I have made extensive use of the Cambridge Edition of the Works of Immanuel Kant, where available, and of translation of the Anthropology by Victor Lyle Dowdell (Southern Illinois University Press: 1978) and Mary Gregor (Martinus Nijhoff: 1974).)
[2] 4:455.
[3] 5:99. Despite these apparently clear statements, some
have recently claimed that there is no Kantian basis for maintaining causal
determinism in the psychological realm (Westphal 1995: 362, Gouax 1972):
Kant
himself held it to be one of the cardinal achievements of the Critical
philosophy, forever to foreclose on both materialist and spiritualist
explanations of the mind
. Those are
the only two kinds of causal explanations countenanced in the Modern
period. To foreclose on such explanations
in psychology is (for . . . Kant) to foreclose on the scientific status
of psychology. (Westphal 1995: 358)
There are two sorts of
criticism generally raised against the notion of a Kantian account of causal
laws governing mental states. The first
and most radical claim, articulated here by Westphal, is that for Kant there
simply are no causal laws governing human psychology. The second claim, which is often connected (e.g., by Westphal)
with the first, is that psychology can never rise to the level of a science.
In general, there are also two lines of argument to
establish each of these claims. The
first argument is based on the requirements for human freedom. Briefly, the argument is that because of
Kants emphasis on human freedom, he cannot allow for a science that explains
human actions in terms of causal laws.
Westphal thus claims that Kant needs Critically justified theoretical
reasons for denying [determinism in psychology] in order to permit himself to
describe the human will as . . . liberum (357-8). I discuss this argument with respect to
Reath and Baron in the body of the paper, so I will not take it up here. The second kind of argument, primarily used
to establish the impossibility of psychology as a science, is based on Kants
disparaging of psychology in the Metaphysical Foundations of Natural Science. There Kant says,
The
empirical doctrine of the soul must always remain even further removed than
chemistry from the rank of what may be called a natural science proper . .
.. It can . . . never become anything
more than a historical (and as such, as much as possible) systematic natural
doctrine of the internal sense, i.e., a natural description of the soul, but
not a science of the soul, nor even a psychological experimental doctrine. This is the reason why . . . the general
name of natural science . . . belongs to the doctrine of body alone. (4:471, see too 28:679)
Many (e.g. Gouax 1972) have
taken this passage to imply that Kant opposes any kind of serious empirical
study of the causal principles underlying mental life, and some have gone as
far as to use this to argue against causal necessity in human actions.
However, Kants argument against
psychology as a science employs very specific objections to psychology
as a science, and Kant allows that psychology can be a historical
systematic natural doctrine of the inner sense (4:471) and even a natural
science . . . improperly so called, . . . [which] would treat its object . . .
according to laws of experience (4:468).
As Hatfield (1990, 1992), Sturm (2001), and others argue, Kant objects
to applying to psychology a very particular conception of science, as a study
whose certainty is apodictic, which must thus consist in a priori
principles (4:468) and in particular in the application of mathematics to
its subject matter (4:470). Hatfield
rightly points out,
While
we must give these remarks [in MFNS] their due, they should not be allowed to
obscure Kants basic position that the phenomena of empirical psychology are
strictly bound by the law of cause just as are the phenomena of physics. (Hatfield
1992: 217)
Neither Kants concern with freedom, nor his prohibition of a science of psychology show that human beings are not governed by causal laws, nor even that we cannot discern (some of) those causal laws.
[4] 5:98.
[5] Wood 1984:74. Woods phrase here gives a nice way to distinguish different accounts of Kants moral psychology. Some, such as Henry Allison, basically endorse Woods view (see Allison 1990:28). Others, such as Hud Hudson (and arguably Christine Korsgaard), defend Kantian compatibilism at the cost of Kantian incompatibilism. And still others, such as Reath and Baron, implicitly defend Kantian incompatibilism without sufficient attention to Kants compatibilism.
[6] Wood 1984:74.
[7] This defense of freedom might not be fully satisfying, but it is Kantian. Wood 1984, Allison 1989, and Frierson 2003 have offered more detailed arguments for this view. For the purposes of this paper, I simply take this general account of Kants theory of freedom for granted, with the little support I have already offered here. I generally agree with Woods account of Kants theory of freedom, as developed in Wood 1984. The one issue on which Wood and I disagree is that I see Kant as claiming that actions that follow from reason are just as causally determined as actions that proceed from purely sensuous influences. Occasionally (e.g. pp. 78, 83, 87) Wood seems to suggest that nature only determines action through sensuous influences. As we will see in the course of this paper, reason is just as natural as the senses, from within the perspective of empirical psychology.
[8] 28:773, cf. 28:682, A535/B563.
[9] Of course,
this determinism is only empirical determinism, not determinism all the
way down. Human actions are
empirically determined in the sense that these actions follow from prior causes
in accordance with laws of nature. But
these actions are still ultimately ascribed to transcendentally free agents,
where this freedom consists in those agents not being determined at a
noumenal level by empirical causes.
This is discussed in detail in Wood 1984 and Frierson 2003: 13-30.
It is also worth noting that at this point, there is room for Kant to tell some causal story about human action, but his transcendental idealism does not imply any particular story. Given Kants transcendental philosophy, freedom of the intelligible character can be preserved regardless of the picture at the empirical level. Paul Guyer has even suggested, on these grounds, that the subjective state of ones feelings can, perhaps even directly, reflect the moral choices of ones will (Guyer 1993: 367). In fact, Kant develops a very particular conception of human action at the empirical level, one that is influenced by and related to his contemporaries accounts, but not identical with them, but his overall transcendental philosophy could support a variety of different empirical psychologies. {part of footnote deleted for the sake of anonymity}

[13] Thus even Gouax, who argues that the First Analogy is not applicable to objects of inner sense (1972: 240) is forced to admit that it is possible to apply causality [the Second Analogy] to inner alterations. And while Gouax insists that surely causality applied to inner alterations is a weak notion (1972: 240), he offers no textual basis for this claim.
[14] Baron 1995, p. 189.
[15] Baron 1995, p. 189.
[16] Baron 1995, p. 189. Baron does not quote the whole passage here, and thus gives the impression that Kants argument for freedom is based on a kind of introspection of a felt power to choose otherwise. She cites Kants suggestion that if someone claims that his lust is irrestible, ask him whether he would not control his passion if, in front of his house where he has this opportunity, a gallows were erected on which he would be hanged immediately after gratifying his lust (PrR 30) (Baron 1995: 189). Kant goes on to argue,
But ask him whether, if his prince demanded, on pain of the same immediate execution, that he give false testimony against an honorable man . . ., he would consider it possible to overcome his love of life . . .. He would perhaps not venture to assert whether he would do it or not, but he must admit without hesitation that it would be possible for him. He judges, therefore, that he can do something because he is aware that he ought to do it. (5:30, emphasis added)
On the basis of conjectural introspection, one would perhaps not venture to speculate about ones capacities, but one can infer that one is able to do something from the moral (and thus not psychological) fact that one ought to do it.
[17] Even Jeanine Grenberg, who is much more sensitive than most Kant commentators to the details of Kants psychology, admits that Kants language of impulsion certainly does suggest that . . . he is . . . advocating a more mechanistic theory of action but argues that this is not in fact the case, that in fact human actions do not follow the laws of nature. (Grenberg 2001. The first quotation is from p. 151, the second from p. 175.)
Grenberg seems to locate the freedom of action in our capacity to control the representations that give rise to desires (and thereby actions). She asks How does an appeal to representation distinguish feeling from mere physical force? That which evokes feelings is not, strictly speaking, a force completely external to an agent, but rather any state of affairs in so far as it has been taken up by an agents capacity to represent it to herself (161). But of course, this contrast between internal and external causes is one with which any empiricist would agree, and one that Kant specifically argues is not sufficient for the kind of freedom that is needed for moral responsibility (see 5: 97f.). And one would not expect this merely empirical freedom to be particularly important to distinguish Kants accounts from his more determinist contemporaries, since Kant saw his contribution to freedom of action to lie not in a novel psychological account of empirical freedom but in a new transcendental freedom compatible with thoroughgoing natural determinism.
At times, Grenberg seems sensitive to this point. She is much clearer than other commentators about the specifically first-personal nature of freedom in Kants psychology, saying for example that when [an agent] judges her feeling of pleasure to be good . . . she attributes it to her own faculty of desire, not from a third person perspective, but from a first person perspective, and she distinguishes this practical task from theoretical . . . knowledge of herself as object (171). But this distinction does not sufficiently inform her overall treatment of Kants account of action, such that she still seems to think that there is a conflict between Kantian freedom and a thoroughgoing natural necessity in psychological explanations of human action.

[21] The primary resources here are hints within Kants three Critiques but especially his Anthropology from a Pragmatic Point of View, as well as Reflexionen and lecture notes on anthropology and metaphysics. The lectures on metaphysics, in particular, give Kants most systematic treatment of empirical psychology. While there has been some question about the veracity of these lectures, they have increasingly been taken to be reliable, largely because of their overlap with each other and with Kants published writings. (See the introduction to the Cambridge Edition of the Lectures on Metaphysics for more details on their reliability.) I generally take these lectures to be reliable, while making some effort to back up key interpretative claims with references to published works.
[22] The recent publications of these lectures in English, as part of the Cambridge Edition of the Works of Immanuel Kant, will make the study of Kants empirical psychology much easier within the English-speaking world. The forthcoming publication of Kants works and lectures on anthropology in the same series will hopefully have a similar result.
[23] For details on the relationship of these three strands to Kant, see Beck 1969; Hatfield 1990: 21-77; Henrich 1957/58 and 1994: 20-7, 70-2; Hilgard 1980; and Schneewind 1998. For a close study of the reception of Scottish philosophy in 18th century Germany, see Kuehn 1987. Other figures are relevant to Kants psychology, including Tetens, Eberhard, Mendelssohn, and Lossius, but a full discussion of the historical background of Kants psychology is beyond the scope of this essay. Baumgarten and Mendelssohn are particularly important in that both articulated similar three-fold divisions to Kants own (cf. Hilgard 1980).
[24] cf. 29:877.
[25] 28:564.
[26] Kant explains that he groups the essentially distinct powers into 3 classes in order to treat empirical psychology all the more systematically (28:262).

[29] Kant would have known of Humes philosophy, at least through Sulzers translation of Humes Inquiry. For more on the connections between Kant and Hume, see especially Henrich 1957/58 and 1994, Kuehn 1987, and Hatfield 1990.
[30] For the law of association governing the imagination, see 7:174ff. and corresponding sections in his lectures on anthropology (e.g. 25: 883) and empirical psychology (e.g. 28:585, 674). Baumgarten too draw attention to laws of association governing the imagination (see Baumgartens Metaphysica, §561), but this law was particularly prominent among British empiricists (see e.g. Hume 1740: I.iii.vi.4, pp. 88-9 and I.iii.vii.6, p. 97: we are not determined by reason, but by . . . a principle of association). I argue in section 6 that the comparison of Kant and Hume can also help one see the ways in which some of Kants apparently logical claims about the understanding can be read as causal ones.
[31] 25:1514, cf. 29:1024. For Kant, all action proceeds from a prior determination of the faculty of desire. Thus within Kants empirical account, at least, it is not the case, as Simon Blackburn has suggested, that motivation by means of desire was one thing, motivation by apprehension of the Moral Law a different thing (Blackburn 1998: 214). Desire, as the faculty giving rise to action, is necessarily involved in any human action. (That said, Kant distinguishes between different sorts of desire, including a desire in the narrow sense (6:212) that is not necessarily involved in every action.)
[32] 29:1012, cf. 6: 211, 399; 7:251.
[33] One caveat must be added here. For Kant, the tendency of a representation to maintain that representation itself without bringing about a change in the world does not count as a desire. This is how Kant accounts for aesthetic pleasure, where one seeks to maintain a representation but without any desire for an object of that representation, and Kant is particularly interested in these cases of disinterested pleasure (cf. 28:674-5.) The fuller context of the passage quoted at this footnote reads,
We have pleasure or displeasure without desiring or abhorring, e.g. if we see a beautiful area, then it enchants us, be we will not on that account wish at once to possess it. Pleasure or displeasure is thus something entirely different from the faculty of desire. But on the other hand we can desire or abhor nothing which is not based on pleasure or displeasure. For that which give me no pleasure, I also do not want. Thus pleasure or displeasure precedes desire or abhorrence. But still I must first cognize what I desire, likewise what give me pleasure or displeasure; accordingly, both are based on the cognitive faculty. There are also many representations which are connected with neither pleasure nor displeasure, and thus the cognitive faculty is wholly distinct from the feeling of pleasure or displeasure. (29:877-8)
Kants aesthetics is largely foreshadowed in his empirical psychological discussions of feelings that do not give rise to any desire. This is a rich and complex part of Kants empirical psychology that I forego here, but for more, see Kants accounts of feeling in his lectures on metaphysics and anthropology, and his account of the beautiful in the Critique of Judgment and in Observations on the Feeling of the Beautiful and the Sublime. The nature of aesthetic pleasure has been discussed at length in secondary literature. For some examples, see Allison 2001, Ameriks 2003, and Guyer 1979, 1993.
[34] 29:877-8. This account of human action is identical for animal action. Like humans, other animals have cognitions, feelings, and desires. Kant even describes animals as having choice [Willkühr] (cf. 6:213, 28:588, 29:1015). The difference between humans and animals is that humans have a higher faculty of cognition, and hence of desire, and this gives humans a kind of empirical freedom than animals lack. This shows that at least Kants general picture of human action does not imply any transcendental freedom. Kant nowhere suggests that animals have transcendental freedom, so insofar as they are motivated by similar structures as human beings, there is nothing free about these structures in themselves.
[35] There is one complication to this picture that I will not discuss here. When discussing the higher faculty of desire (see below), Kant sometimes suggests that pleasure does not precede desire. Some of the strongest language here is from the second Critique, where Kant says,
What is essential to any moral worth of actions is that the moral law determine the will immediately. If the determination of the will takes place conformably with the law but only by means of a feeling, of whatever kind, that has to be presupposed in order for the law to become a sufficient determining ground of the will, so that the action is not done for the sake of the law, then the action will contain legality indeed but not morality. (5:71-2)
This passage could be read merely to refer to first personal grounds of choice rather than to empirical causes of choice, but it might also be read psychologically. The former interpretation, which fits better with the account of pleasure offered in this paper, is supported in part by Kants appeal later in this discussion to a positive feeling of respect for the moral law (5:73), a moral feeling . . . produced solely by reason that serves as an incentive to make this [moral] law its [the wills] maxim (5:76). For detailed studies of these passages, see Allison 1989, McCarty 1993 and 1994, and Reath 1989. A similar tension between an intellectual feeling that causes choice and an insistence that feeling must play no role occurs throughout Kants lectures and other writings. Thus in the Metaphysics of Morals, Kant distinguishes between an interest of inclination where a pleasure necessarily precedes a desire and an intellectual pleasure that can only follow upon an antecedent determination of the faculty of desire (6:212, cf. 29:1024).
But in a lecture of the same period (1794-5), Kant deals with the issue of pleasure differently. He first distinguishes between pleasure (Lust) and satisfaction (Wohlgefallen), the latter of which is more general (29:1013) and includes both intellectual and sensible satisfaction. (In this context, pleasure describes the subset of satisfaction that is purely sensible.) But Kant then claims that desiring has its ground in satisfaction with respect to the actuality of the object (29:1013). (Even in that set of lectures, however, Kant distinguishes between the higher and lower faculties of desire by saying that the impelling causes of an action lie either in the understanding as the law of action [in which case the cause is a higher desire], or in the sensibility, namely, in the feeling of pleasure and displeasure, in which latter case the cause is a lower desire (29:1014). Here Kant seems to conflate sensibility with feeling and to associate both exclusively with the lower faculty of desire.)
In an earlier lecture (1782-3), Kant is even more explicit about the fact that pleasure must precede desire: we can desire or abhor nothing which is not based on pleasure or displeasure. For that which gives me no pleasure, I also do not want. Thus pleasure or displeasure precedes desire or abhorrence (29:878). Later in that lecture he reiterates that representations cannot be the cause of an object where we have no pleasure or displeasure in it, adding that the faculty of desire rests on the principle: I desire nothing but what pleases (29:894). In this context he distinguishes higher and lower faculty of desire based on whether they are caused by sensibility or the understanding (see 29:895, 28:254).
Overall, Kant seems to have two basic models for human action. On one model, Cognition ā Pleasure ā Desire ā Action. Here the difference between respect for the moral law and action from sensuous incentives is that the relevant pleasure in the case of respect is a pure intellectual pleasure. This strand in Kant confirms those like McCarty who endorse an affectivist reading of Kant. On the alternative model, Cognition ā Desire ā Action and Pleasure, where again the relevant pleasure here is purely intellectual, but now it plays no motivational role at all and is simply an co-effect (with action) of the desire. At least in the account in the second Critique, this second picture also seems to involve a direct negative action of pure practical reason on sensuous feelings, by which it derives self-love of its influence (5:75) to make room for the direct action of pure cognitions on the faculty of desire.
[36] Kant suggests that smell and taste are paradigm cases here, and their connection is particularly important in this regard. See 8:111.
[37] Grenberg 2001: 160-3. For another very helpful account of Kants theory of pleasure in action, which makes some important distinctions that Grenberg ignores, see Morrison (forthcoming).
[38] Grenberg 2001: 163. Grenbergs account of the connection between pleasure and desire is supported in the passages in Kants Metaphysics of Morals from which she draws her account. There, as Grenberg points out, Kant simply defines practical pleasure as that pleasure which is necessarily connected with a desire (for an object . . .) (6: 212). In his Anthropology, Kant similarly explains that
[P]leasure . . . and displeasure through the senses . . . can [be] describe[d] . . . in terms of the effect that the sensation of our state leaves on the mind. What directly . . . prompts me to leave my state (to go out of it) is disagreeable to me it pains me. What directly prompts me to maintain this state (to remain in it) is agreeable to me it gratifies me. (7:230-1)
Admittedly, this passage focuses on sensuous pleasures in particular, and thus need not apply to aesthetic or intellectual pleasures. For issues surrounding the nature of intellectual pleasures, see footnote 35.
As I indicated in footnote 33, I follow Grenberg in largely bracketing the issue of aesthetic pleasure. Aesthetic pleasure is not prominent in Kants account of action, and though it raises important issues for his overall empirical psychology, these issues go beyond the scope of both Grenbergs paper and mine.
[39] There is more that could be done with respect to Kants theory of the role of pleasure in action. Two issues in particular merit further attention. First, Kants empirical psychology is unique in sharply distinguishing between feeling and desire, and his basis for this distinction is his account of aesthetic pleasure. I am inclined to agree with Iain Morrison, who argues that it is the nature of all pleasure to want to maintain itself, and that the difference between aesthetic and practical pleasure is simply that in the case of the former, the way that the state of mind can preserve itself is . . . by simply maintaining contemplation . . ., [while] in practical matters the pleasurable state of mind maintains itself by bringing forth the contemplated object (Morrison (forthcoming)). But this account of the relationship between aesthetic pleasure and practical pleasure in the context of Kants empirical psychology needs to be further developed.
Second, with respect to the higher faculties of cognition, feeling, and desire, Kants account seems to shift throughout his lectures and published writings. I discussed this to some extent in footnote 35, but more work needs to be done making use of Kants empirical psychology to develop an overall picture of Kants views on the nature of intellectual pleasure.
[40] 28:228, 29:880, 28:584.
[41] In some cases, Kant associates the spontaneity of the higher faculty with that transcendental freedom that is a condition of possibility of moral responsibility. Strictly speaking, describing the higher faculty of desire as free in that sense is inconsistent with empirical psychology. Insofar as one studies human action empirically, such action is, as Kant insists in his first Critique, causally necessitated in accordance with nature laws. But Kant does hold that the present of a higher faculty of desire is an indication of moral responsibility and hence transcendental freedom. (See {part of footnote deleted for the sake of anonymity}) Thus he sometimes slips into these properly transcendental discussions in lectures on empirical psychology. This effort to discuss the Critical philosophy in lectures on empirical psychology is not particularly surprising, of course. As a teacher, Kant found an opportunity within the syllabus prescribed by Baumgartens text for explaining some of Kants own more important philosophical ideas, a temptation to which he can hardly be blamed for succumbing.
[42] See Beck 1987, pp. 35-6 for a helpful account of this sort of freedom. This comparative freedom is the freedom that Kant refers to in the second Critique as the freedom of a turnspit (5:97). Brian Jacobs puts the point well in the context of discussion the nature of freedom of the higher faculty of desire (the will) in Kants anthropology: the arbitrium liberum that Kant posits against the animalistic arbirtium brutum . . . is a practical empirical concept and one that is observable when a human being resists acting solely according to the pathological necessity that characterizes animal will (Jacobs 2003: 120).
[43] Cf. 7:140-1, 153ff.; 25:29f., 269f.; 28:59f., 230f., 585, 672f., 869f., 737f.; and 29: 882f.
[44] Cf. e.g. 7:196, and related sections of lectures in empirical psychology (28:73-5, 242-3, 863-5; 29: 888-90) and anthropology (25: 537, 773-4, 1032f., 1296, 1476) Kants placement of the power of judgment (Urteilskraft) in the higher cognitive faculty is a notable departure from Baumgarten, who places it in the lower cognitive faculty (see Metaphysica §§ 606-9). A detailed comparison of Baumgarten and Kant on the nature of judgment would reward further study but it beyond the scope of the present paper.
[45] 29:877.
[46] For complications related to bracketing the issue of freedom here, see footnotes 34 (above) and 47 (below).
[47] 29:894.
[48] Kant makes the same claim in the context of pleasure, but there Kant is careful to insist that on the one hand all pleasure is sensitive in itself (hence lower) but there is still a lower and higher faculty of pleasure. See too footnote 35 for Kants shifting views on the nature of higher pleasure.
[49] 28: 674-5.
[50] Kant actually says act of the faculty of choice here, but he has just explained that the faculty of choice is simply the faculty of desire insofar as it operates in a context where its activity can bring about its object (28:254).
[51] 28:254, cf. 29:895.

[54] 29:1014.
[55] 29:1015.
[56] 28:589, emphasis added.
[57] One way of putting this is that higher desires are those for which Allisons incorporation thesis holds. For Kant, contra Allison, human beings can, sometimes, act purely from instinct or inclination, without incorporating such instincts or inclinations into any principle of the understanding. Kants language to describe such actions fits the lack of true agency implied by their failure to fits Allisons account of incorporation. He refers to them as actions proceeding from stimuli or impulse. Most actions, even those that are not guided by morality, are free in the sense that they are associated with the higher faculty of desire, where one acts on principles or maxims, even if these maxims take the satisfaction of inclination as their end. But one can also act directly from lower desires. (This may help explain both the role of affects in Kants philosophy and Kants treatment of weakness of will.)
[58] This distinction is somewhat different than the discussion of higher and lower faculties in the Critique of Practical Reason. There Kant discusses the distinction in the context of arguing against heteronomous ethical theories, and he downplays the difference between pure and affected higher desires. In the account in the second Critique, he argues against those who describe the higher faculty of desire as one within which intellectual cognitions cause pleasure and thereby move the will. By contrast, he insists upon a higher faculty of desire as the ability for pure reason . . . to determine the will without some feeling being presupposed (5:24). These passages can be thought of from two perspectives. If interpreted as empirical psychology, this passage could be part of Kants more general shift away from the Cognition ā Pleasure ā Desire ā Action model of motivation in the context of the higher faculty of desire. For more on Kants shifting views in this respect, see footnote 35. More likely, however, Kant is here arguing from within the practical perspective. From that perspective, choosing to act to pursue the pleasure acquired from intellectual activity is just as sensuous because based on pleasure as choosing to pursue any other pleasure.
[59] 28: 254.
[60] 28:564.
[61] Feelings that do not give rise to desire or aversion are particularly important for Kants aesthetics (cf. footnote 33).
[62] A natural predisposition indicate[s] what can be
made of a man by nature, as opposed to what man is prepared to make of
himself (7:285). The concept is closely
related, for Kant, to the notion of a germ (Keime). (For more on Kants account of Anlagen,
as well as the relationship between Anlagen and Keime, see Munzel
1999 and Sloan 2002.) Kant discusses Anlagen
throughout his philosophy. In his
lectures on metaphysics, Kant most commonly uses claims about natural
predispositions to argue for the immortality of the human soul. As he puts it in a lecture from the early
1790s,
The
proof of the immortality of the soul is grounded on the principle of the analogy
of nature. Nature has placed in all
living organic beings no more predispositions than what they can make use of .
. .. We find in us a [moral] summons to
sacrifice the greatest advantages, without receiving in life the slightest
advantage for it. Here is a
predisposition in human nature, and this is just as purposive, according to the
analogy of nature, as all predispositions of nature. We thus infer a future life where the use of these
predispositions and their end first can be attained. (28:765-6, cf. 29: 916-7, 1040)
Here the notion of a predisposition is quite broad including all end-directed faculties in animals, and even their organs, which are not given any larger than they can make use of (28:765). In the Religion, Kant makes use of the notion of a predisposition to good to explain the nature of radical evil. And in his Critique of Judgment, Kant discusses the natural predispositions of human beings in the context of his general argument that human beings are the ultimate end of nature (cf. 5:340-1).
[63] 8:110.
[64] This modesty is epistemic. Kant elsewhere argues that as a metaphysical matter, it is obvious that there is only one basic power in the soul . . . But this is a wholly other question: whether we are capable of deriving all the actions of the soul, and its various powers and faculties, from one basic power. This we are in no way in the position to do (28:262). Although Kant does not emphasize this point in other lectures, there is nothing in his later claims that precludes the possibility of all human powers in fact being reducible to a single one. But when it comes to empirical psychology, we are not justified in trying to effect this reduction. For more on the important difference between limits on human explanation and limits on metaphysical possibility, see Ameriks 2003.
[65] 29:935-6.
[66] 29:773, 822. Here again (recall footnote 64)., Kant leaves open the metaphysical possibility that the unity of each substance requires that there be only one basic power (29:822).
[67] 2:434
[68] 5:400
[69] It is also worth noting here that this limitation on mechanist explanation puts Kant in good company with other naturalist explanations of human beings. Hume, for example, argues,
When we see, that we have arrived at the utmost extent of human reason, we sit down contented . . .. But if this impossibility of explaining ultimate principle should be esteemed a defect in the science of man, I will venture to affirm, that tis a defect common to it with all the sciences . . .. (Hume 1740, Introduction ļ9, p. xviii)
If Kants dependence on stipulated principles of human action without further explanation rules him out of the ranks of determinist empirical psychologists, then Hume must also be ruled out of those ranks.
[70] Sloan 2002: 232
[71] Sloan 2002: 233
[72] Sloan (2002) has detailed the role of Keime in Kants biology. He also argues persuasively for the introduction of Anlage as a technical term that provides Kant a middle way (238) between strict preformationism and vitalist epigenesis. For the purposes of this paper, the details of that account are not needed.
[73] For more detail, see Sloan 2002.

[86] Kant even seems to think that mechanist explanations are available in principle for any event in the world. Unlike Kants claims in the first Critique that it is impossible to know things in themselves, his claim that there will never be a Newton of a blade a grass does not seem to be a claim about what is in principle possible for human beings. Rather, he seems to think that mechanist explanations of biological phenomena are simply too complex for exhaustive comprehension for human beings.

[104] 25:1514.
[105] 25:1111-2. Kant adds here, One can put instinct between propensity and inclination. Like propensities, instincts are innate in human beings. Like inclinations, instincts provide direct explanations for various desires. (Kant is not entirely consistent about the relationship between inclinations and instincts. Generally (e.g. 25:111-2 and 7:265) he distinguishes between them as two different sorts of explanation for desire. But elsewhere he draws lines a bit differently. In a metaphysics lecture from 1782-3, Kant reportedly says, If the stimuli <stimuli> have become habitual, then they are inclinations and their source is instinct or habit (29:895), suggesting that the source of some inclinations is instinct. And elsewhere (25:1518) Kant says that the inclination [Neigung] of parents towards their children is also instinct. The account that I give here of the relationship between instinct, inclination, and propensity is the dominant one in Kants published works and lectures, but occasionally, at least according to his students, Kant relates instinct and inclination in different ways.)
[106] 7:265, cf. 25:1517.
[107] 25:1339.
[108] 25:1339.
[109] In fact, Kant periodically changes the relevant people-group in discussing this example. His overall view seems best captured by his claim that Human beings across the whole world have a propensity to drink [alcohol] (25:1112), as an example of which he sometimes uses northern peoples (25:1339), sometimes the wildest peoples (25:1112), sometimes nations that have wine (25:1518), and once even the people in Kamtschatka, [who] have a certain cabbage, which when they eat it, works in them a kind of madness, for which they love to have it (25:1518). The point of these examples is not to pick out any particular group, but to show that this propensity is universal. Thus the passage in the Religion, often taken as an offensive way of distinguishing savages from Europeans, actually reflects the fact that the propensity to drink was undeniable in the case of Europeans, but some might claim that this propensity itself is acquired, against which Kant cites the case of savage, or raw (rohe), people.
[110] 6:29.
[111] We can make the pictures a bit more complicated by inserting the distinction between feeling and desire. Then the account for instinct will look as follows (and the account for inclination will be altered in just the same way):
Sensory cognition ā Anticipatory Pleasure ā Desire
↑ ↑
Instinct* Nature of pleasure
The notion of anticipatory pleasure refers to the pleasure that causally effects the desire, in contrast to any expected future pleasure or past pleasures that may have cultivated ones inclinations. For more on the nature of anticipatory pleasure, see Morrison 2004. Because the nature of pleasure will always explain the connection between anticipatory pleasure and desire, I have simplified the diagrams in the rest of my discussion by conflating pleasure and desire.
[112] What it means here to say that instinct explains the desire to suck is just that the natural scientist is leaving the desire to suck unexplained, allowing the positing of a new causal law Humans desire to suck. Likewise the propensity to drink alcohol is a simply a new causal law northern peoples or savages will desire alcohol if they experience it.

[119] For more on the nature of character, and especially how ones character can be evil and still admirable, see Frierson (forthcoming JHP).
[120] 7:285.
[121] Kant even suggests that those who do not act consistently on the basis of principles have a kind of bad character (schlechte Character, cf. 25:650, 1172). This character is not a character in the strict sense, because it does not involve acting consistently on principles of the understanding, but it is a state of character in that it provides a basis for explaining why the connection between principles and desires is not constant. Thus it plays an explanatory role in an unstable causal account.

[135] 25: 635, cf. 7:325; 5:154; 25:599, 722ff., 1386. Kant even gives recommendations about different ways to teach boys and girls (25:1392), suggesting that the influences on character can get quite fine-grained.
[136] 5:156.
[137] 5:156.
[138] Kant emphasizes the empirical nature of this potential for motivation by moral reason in the second Critique. He introduces his account of educating the ten-year-old boy by claiming that We will . . . show, by observations anyone can make, . . . this property of our mind, this receptivity to a pure moral interest and hence the moving force of the pure representation of virtue (5:152, my emphasis). Just as one presents empirical reasons for believing in various human instincts, propensities, and inclinations, so one can show by observation that human beings have an innate possibility for moral motivation. And the receptivity that one finds in human beings for such motivation is precisely a receptivity to empirical influences, such as the telling of a vivid story of moral virtue. And this receptivity is itself the result of empirical causes, though human science may never be able to discern precisely how it arose from them.
[139] 5:155.
[140] 6:479f.
[141] Elsewhere Kant points out that even in adults, one can directly influence whether another acts on the basis of the moral law. As he explains,
This happens when the other . . . confronts the
subject with . . . the moral law by which he ought to act. If this confrontation makes an impression on
the agent, he determines his will by an Idea of reason, creates through his reason
that conception of his duty which already lay previously within him, and is
only quickened by the other, and determines himself accordingly to the moral
law. (27:521)
Kants emphasis on the role of reason, and even an Idea of reason, should not distract from what is actually going on here. One person is able, through conversation, to cause another to have a new higher cognition, an Idea of reason, and this higher cognition in turn causes a new determination of the faculty of desire, according to which the person acts morally. This is, for Kant, an example of how a person may be compelled to duty by others (27:521).
[142] For more on the role of politeness in cultivating character, see Brender 1997, 1998, and Frierson (forthcoming Kantian Review).
[143] 8:375. Brian Jacobs has pointed out that as he makes clear from his Idea essay of 1784, Kant thinks that precisely these aspects of human life [social, cultural, political, and historico-teleological characteristics] are as determined as natural events (Jacobs 2003: 112).
[144] 7:329.
[145] Kants account of the origin of character is not limited to external influences on character. He claims, for instance, that the cultivation of ones propensity to character comes through understanding and reason (25:1172). (Immediately after saying this, however, Kant reiterates that the acquisition of . . . character . . . happens through education. For Kant, cultivating character through reason and understanding is a pedagogical task, not a solely individual accomplishment.) In that context, Kant discusses several specific rules that one can follow in cultivating character in oneself and others:
a) Not to speak an untruth intentionally .
. ..
b) not to dissemble . . ..
c) not to break ones legitimate promise .
. ..
d) not to join the company of evil-minded
people . . ..
e) not to pay attention to slander . .
.. (7: 294, cf. 25:1387-88, 1392, LA
1789-90: 130)
These are all practical
principles that support and constitute the development of character as
such. The pursuit of these methods for
developing character depends on already having at least some level of
character. Unless one can act on the
basis of principles, one will be unable even to follow the principles for
developing character. But keeping these
principles even sporadically can have some beneficial effect. The more one avoids duplicity, bad company,
and slander, the easier it will be for one to stick to principles in the
future. Insofar as one has some minimal
level of constancy, these principles can reinforce ones character. They are important aids to self-improvement,
even if they are not sufficient.
It is important to note, however, that these are not simply
maxims for self-improvement but maxims based on causal laws governing the
formation of character. Some of the
maxims conducive to character actually embody what character is (for
more on this, see Frierson (forthcoming JHP)). Thus refraining from untruths and dissembling is crucial to
actually being consistent to who one is, to ones principles. To have character just is, in part, to
follow these rules. But the rules also
depend on certain regular connections of causes and effects. Thus one should not join bad company or pay
attention to slander because bad company and slander can causally
interfere with ones development of character.
And even refraining from speaking untruth is an activity that can have a
negative effect on ones development of character.
The
emphasis on practical rules rather than mere causal explanations is, moreover,
particularly appropriate in the context of a pragmatic anthropology,
which seeks not simply to ponder natural causes but to use our
observations for self-improvement (7:119).
(For more on the nature of pragmatic anthropology, see Frierson 2003:
48-56, Louden 2000: 68-70, Wood 1999: 202-7, Brandt and Stark Einleitung to
Ak. 25, and Stark 2003.) For Kant,
explanations of character in terms of natural causes are possible and helpful,
but only if put to use. Thus it
is natural for him not only to give causal explanation but to formulate these
in terms of rules that one can follow in cultivating ones capacity for
character. Kant appeals to causes of
character that are within a persons control for the same reason that he
focuses on causes that are within the control of educators, because these
causes can be put to pragmatic purpose.
The rules for the cultivation of character suggest that there is the possibility of a causal loop in the cultivation of character. Insofar as one begins to develop a character, one can more easily act on the basis of principles. And some principles are conducive to further cultivation of character, so acting on the basis of those will contribute (causally) to a deeper cultivation of character. A causal circle is possible here where small improvements build on each other to produce a character in a full sense. (Admittedly, there is some tension here between this circle, which suggests a gradual development, and Kants appeal to the importance of an explosion (7:295) that suddenly gives rise to character, but a full exploration of problems arising within Kants account of the development of character is beyond the scope of this paper.)

[148] Hume 1740: I.I.ii.1, p. 8. Hume gives a bit more explanation for refusing to consider the origin of sensory impressions, arguing that the examination of our sensations belongs more to anatomists [here meant in the literal sense] and natural philosophers [i.e. scientists of body] than to moral [i.e. psychologists]; and therefore shall not at present be enterd upon (Hume 1740: I.I.ii.1, p. 8).

[151] The senses include, for Kant, not only the 5 outer senses but also the inner sense, and Kant gives an account of that power in his anthropology and empirical psychology. See 7:161f..

[154] 7:176, cf. Hume 1740: I.iii.vi.4 and I.iii.vii.6, pp. 88-9, 97. Kant goes on here to explain that this principle of association is simply a basic causal law, not something that one should seek to reduce to something else: To try to explain this in physiological terms is futile; we are free to use some principle that will always remain a hypothesis (7:176). This positing of a basic principle is consistent with Kants Newtonian conception of scientific explanation, as discussed above.

[159] Strictly speaking, all I have provided here is the basic framework for Kants account. A fully worked out causal account would need to exhaustively catalog all human instincts and propensities and explain their laws of operation.

[164] Here Kant says,
Humanity is easily distinguished from all other natural beings by his technical predisposition for manipulating things (a mechanical predisposition joined with consciousness), by his pragmatic predisposition (for using other men skillfully for his purpose) and by the moral predisposition in his being (to treat himself and others according to the principle of freedom under laws). (7:322)
This list of predispositions is similar to, but importantly different from, the three forms of the predisposition to good in the Religion. To highlight just one important difference, the predisposition to animality in the Religion is not itself rational and is a predisposition (or set of predispositions) that does not distinguish human beings from other living beings on the earth. By contrast, the predispositions in the Anthropology all distinguish humans from animals. For a different interpretation of the relation between these lists, see Kain 2003.
[165] 6:444-5.
[166] In some lectures (e.g. 25: 780), Kant makes a distinction between two different sorts of natural predispositions, talents and capacities, and he claims that the understanding is a capacity (like the senses and imagination) while reason and judgment are talents. Kant uses this distinction to explain different ways that one can promote each faculty.

[172] B1-2.
[173] Similarly in his lectures on metaphysics, Kant explains that with human beings all representations commence with objects of experience, such that in order to obtain cognitions, even concepts of the understanding, our faculty of cognition must be awakened by objects of experience (29:951). But he again quickly points out that there are nonetheless a priori concepts . . . that cannot be derived from experience (29:952, emphasis added).
[174] Jasche Logic, 9: 14. Hatfield (1990: 73) shows how Kant is here opposing the Wolffian reliance on empirical psychology as a source from which logical principles can be borrowed (cf. Wolffs Psychologica empirica, Prolegomena, §§ 4, 5, and 9). Kant, by contrast, studies logic on its own terms, but then uses the insights of logic as a guide to his empirical psychology. Like Wolff, however, Kant maintains a connection between logic and psychology. The difference between the two is that Wolff starts with empirical psychology and uses its principles in his logic. Kant starts with logic but makes use of logical principles for developing his empirical account of cognition. In this sense, Kants approach to the relation between empirical psychology and logic is the opposite of Wolffs.

[180] For both quotes, see 24:721. Cf. too 9: 54, where Kant says, Every error into which the human understanding can fall is only partial, however . . .. For a total error would be a complete opposition to the laws of the understanding and of reason. But how could that, as such, in any way come from the understanding and . . . be held to be a product of the understanding.
[181] A detailed study of empiricist approaches to the higher faculties of cognition would be well worth studying, both for its own sake and for comparison with Kant, but such a study is beyond the scope of the present essay. One might also usefully compare Kant with Wolff here (cf. Hatfield 1990: 72-5), but Wolff is less clearly empiricist than Hume.
[182] Hume 1740: I.iii.vi.4, pp. 88-9. This passage has been discussed in detail among Hume commentators. Cf. e.g. Baier 1994, Garrett 2002, and Stroud 1981.
[183] But see footnote 9. Kants account is less determinist than Humes in that there is more to the story than determinism. Unlike Hume, Kant does not think that the ultimate ground of human actions can be identified with their empirical causes.
[184] There is a good reason for the greater sophistication in Kants account of the higher faculty of cognition. Hume thinks that most belief is the result of principles of the imagination, so his psychology focuses on the nature of that cognitive power. Kants recognition of the possibility of prejudices and disorders as problems with the understanding itself helps support his expanded account of the role of the understanding, and his sense of this expanded role makes him more interested in and attuned to problems specific to the understanding.
[185] For the rest of this section, I focus on the understanding in the narrow sense, though Kants accounts of judgment and reason are similar. With respect to the power of judgment, Kant claims in his logic that the operative laws are induction and analogy, and Kant discusses various kinds of syllogisms related to reason (9:132, 133f.). In both cases, Kants account is brief. (Perhaps the most extensive detail with regard to the ways in which reason can be unhealthy is in Kants first Critique accounts of the illusions of reason in the transcendental dialectic. In his anthropology, Kant explains that illusions can cause higher cognitive faculties to diverge from the rules that govern healthy reason: to avoid errors . . . one must seek to disclose and to explain their source: illusion (Jasche Logic, 9:56). And the account in the first Critique shows several examples of this divergence. For more on illusions of reason in the first Critique and Kants early theoretical writings, see Grier 2001.)
Again, Kants primary interest in his empirical accounts of the higher cognitive faculties is practical. In this context in particular, he points out that while the understanding can be educated, the faculty of judgment can only be trained (geubt) or cultivated (cultiviert). (For geubt, see 7:199 and 25:777. For cultiviert, see 25:1476. Cf. too 24:722; 25: 774, 1477; 29:890.)
