PRACTICAL REASON

[Bx] In the Preface to B, Kant speaks of theoretical reason as "determining" a given concept and of practical reason as "making it actual". In addition to distinguishing the practical employment of reason from its speculative employment, Kant opposes practical and transcendental freedom. [Bxxv] He suggests that in practical reason we may pass beyond the limits of possible experience, and characterizes the Critique's limitation of speculative reason as essential for clearing the way for practical reason, "the necessary practical employment of pure reason--the moral--in which it inevitably goes beyond the limits of sensibility. Without the negative aspect of the Critique, the practical employment of reason is in jeopardy because reason is "brought into conflict with itself".
