The Critique of Practical Reason
Kant · en
independence on everything empirical, and, consequently, on nature
generally, whether it is an object of the internal sense considered in
time only, or of the external in time and space. Without this
freedom (in the latter and true sense), which alone is practical a
priori, no moral law and no moral imputation are possible. Just for
this reason the necessity of events in time, according to the physical
law of causality, may be called the mechanism of nature, although we
do not mean by this that things which are subject to it must be really
material machines. We look here only to the necessity of the
connection of events in a time-series as it is developed according
to the physical law, whether the subject in which this development
takes place is called automaton materiale when the mechanical being is
moved by matter, or with Leibnitz spirituale when it is impelled by
ideas; and if the freedom of our will were no other than the latter
(say the psychological and comparative, not also transcendental,
that is, absolute), then it would at bottom be nothing better than the
freedom of a turnspit, which, when once it is wound up, accomplishes
its motions of itself.
Now, in order to remove in the supposed case the apparent
contradiction between freedom and the mechanism of nature in one and
the same action, we must remember what was said in the Critique of
Pure Reason, or what follows therefrom; viz., that the necessity of
nature, which cannot co-exist with the freedom of the subject,
appertains only to the attributes of the thing that is subject to
time-conditions, consequently only to those of the acting subject as a
phenomenon; that therefore in this respect the determining
principles of every action of the same reside in what belongs to
past time and is no longer in his power (in which must be included his
own past actions and the character that these may determine for him in
his own eyes as a phenomenon). But the very same subject, being on the
other side conscious of himself as a thing in himself, considers his
existence also in so far as it is not subject to time-conditions,
and regards himself as only determinable by laws which he gives
himself through reason; and in this his existence nothing is
antecedent to the determination of his will, but every action, and
in general every modification of his existence, varying according to
his internal sense, even the whole series of his existence as a
sensible being is in the consciousness of his supersensible
existence nothing but the result, and never to be regarded as the
determining principle, of his causality as a noumenon. In this view
now the rational being can justly say of every unlawful action that he
performs, that he could very well have left it undone; although as
appearance it is sufficiently determined in the past, and in this
respect is absolutely necessary; for it, with all the past which
determines it, belongs to the one single phenomenon of his character
