Apperception and Self-Knowledge in Kant

In several places of his work, Kant distinguishes between two senses of self-consciousness: a pure one and an empirical one. The aim of this work is to analyze these two senses of consciousness and show that, for Kant, self-consciousness does not occur unrestrictedly: a relation with something other than consciousness is needed for it to become conscious of itself. I carry out these objectives throughout six sections. In the first one I lay out the Kantian principle of pure apperception. In the second one, I present the limits of pure apperception through Kant’s critique of rational psychology. Then, in the third section, I set the basis to understand the relationship that Kant establishes between the I think and the I exist. In the fourth one I show that pure apperception, despite being pure, is not possible without the opportunity of perception. Next, in the fifth one, I introduce the notion of empirical apperception, establish its relationship with pure apperception, and elucidate its meaning. Finally, in the last section, I explain the way in which empirical self-consciousness is determined, in relation to the knowledge of objects of the external sense.
