  Starting from (and, Bvii, taking for granted the adequacy of) Aristotelian logic (the syllogisms and the formal concepts that Aristotle called categories), Kant proceeds by analysis to draw out the implications of these concepts and syllogisms for the conceptual structure (the “function of thought in judgment” (A70=B95)) within which all thought and experience must take place. The result is what Kant called the   Categories. That is to say, Kant tries to deduce the conceptual structure of experience from the components of Aristotelian logic.
