Pierre Simon Laplace (1814)
We may regard the present state of the universe as the effect
of its past and the cause of its future.
An intellect which at a certain moment would know all forces that set
nature in motion, and all positions of all items of which nature is
if this intellect were also vast enough to submit these data to analysis
, it would embrace
in a single formula
the movements of the greatest bodies of the universe and
those of the tiniest atom;
for such an intellect nothing would be uncertain and the future just like the past would be present before its eyes.
... This ``intellect'' has been called Laplace's Demon
