Abstract

In the Postulates of Empirical Thinking, a section of the Critique of Pure Reason, Kant presents an account of the content and role of our concept of real possibility in terms of formal conditions of experience. However, much later in the Critique he introduces the idea of a material condition of possibility. What is this material condition of possibility, and how does it fit with the conception of possibility in terms of formal conditions? This essay argues that the key to answering these questions—as well as to understanding Kant’s criticism of rational theology, in which the discussion of the material condition of possibility appears—is Kant’s account of how we can individuate objects.
