This book is a study of the second-edition version of the ‘, Transcendental Deduction’, (the so-called ‘, B-Deduction’, ), which is one of the most important and obscure sections of Kant’, s Critique of Pure Reason. By way of a close analysis of the B-Deduction, Adam Dickerson makes the distinctive claim that the Deduction is crucially concerned with the problem of making intelligible the unity possessed by complex representations - a problem that is the representationalist parallel of the semantic problem of the unity of the proposition. Along the way he discusses most of the key themes in Kant’, s theory of knowledge, including the nature of thought and representation, the notion of objectivity, and the way in which the mind structures our experience of the world.
