Abstract

This paper deals with the “Table of the Categories of Freedom” in the second main chapter of Kant’s Critique of Practical Reason. It provides an account of the role these categories are supposed to play and also of their conceptual content. The key to a proper understanding lies in the realisation that they are derived from the so­called table of judgements in the Critique of Pure Reason and the functions of thinking, which it compiles by means of a metaphysical deduction. I therefore interpret the categories of freedom consistently from the table of judgements and reconstruct their conceptual content from the functions of thinking underlying each category. Furthermore, Kant justifies by means of a transcendental deduction the fact that the categories of freedom necessarily relate to all objects of the will. I argue that the categories are concepts constitutive for the object of the will: the role they play is that of the functions of willing an object. Finally, I show that the categories of freedom reach beyond Kant’s foundation of moral philosophy. They point to the later Metaphysics of Morals in that Kant associates an ambitious system­building claim with them. The idea is therefore that the table of the categories organises the system of moral philosophy.
