Abstract
This paper defends the thesis of the analyticity of the principle of apperception, as developed in the first part of the B-Deduction, against recent criticisms by Paul Guyer and Patricia Kitchen The first part presents these criticisms, the most important of which being that the analyticity thesis is incompatible with both the avowed goal of which being that the Deduction of establishing the validity of the categories and Üie account of apperception in the A-Deduction. The second part argues that Kant's procedure in the B-Deduction of beginning with an abstract analysis of a discursive understanding, independentiy of its relation to the specifically human forms of sensibility, requires him to regard the principle as analytic and that this explains the difference from the A-Deduction. By appealing to the model of a deduction in Kant's moral theory and the two step in one proof structure of the B-Deduction, the third part argues that the analyticity thesis is in fact compatible with the goal of the Deduction.
