  In the Preface and Introduction to the Critique of the Power of Judgment, Kant announces that his goal in the work is to “bring [his] entire critical enterprise to an end” by bridging the “gulf” or “chasm” that separates the domain of his theoretical philosophy (discussed mainly in the Critique of Pure Reason) from the domain of his practical philosophy (discussed mainly in the Critique of Practical Reason) (5:170, 176, 195). In his words: “The understanding legislates a priori for nature, as object of the senses, for a theoretical cognition of it in a possible experience. Reason legislates a priori for freedom and its own causality, as the supersensible in the subject, for an unconditioned practical cognition. The domain of the concept of nature under the one legislation and that of the concept of freedom under the other are entirely barred from any mutual influence that they could have on each other by themselves (each in accordance with its fundamental laws) by the great chasm that separates the supersensible from the appearances” (5:195).
