Abstract

In this paper, I examine the place of the principles “ought implies can” (OIC) and “you can because you ought” (CBO) in Kant’s moral philosophy. Contrary to an often tacit assumption in the relevant literature, according to which CBO is simply a version of OIC, I argue that it is a separate principle, which has a central role in Kant’s attempt to justify morality and freedom on the basis of the consciousness of the moral law as a “fact of reason”. Crucial to my main argument is the somewhat neglected distinction between actuality and reality of freedom, which leads me to a differentiation within CBO itself. This differentiation is of particular importance for understanding in what the deduction of freedom in the second _Critique_ consists.
