can scarcely be serious, and it is probably put forward only as an

Of the Idea of a Critique of Practical Reason.



The theoretical use of reason was concerned with objects of the
cognitive faculty only, and a critical examination of it with
reference to this use applied properly only to the pure faculty of
cognition; because this raised the suspicion, which was afterwards
confirmed, that it might easily pass beyond its limits, and be lost
among unattainable objects, or even contradictory notions. It is quite
different with the practical use of reason. In this, reason is
concerned with the grounds of determination of the will, which is a
faculty either to produce objects corresponding to ideas, or to
determine ourselves to the effecting of such objects (whether the
physical power is sufficient or not); that is, to determine our
causality. For here, reason can at least attain so far as to determine
the will, and has always objective reality in so far as it is the
volition only that is in question. The first question here then is
