The book addresses two main areas of Kant’s theoretical philosophy: the doctrine of transcendental idealism and various central aspects of the arguments from the Metaphysical and Transcendental Deductions, as well as the relation between the deduction argument and idealism. -/- Among the topics covered are the nature of objective validity, the role and function of transcendental logic in relation to general or formal logic, the possibility of contradictory thoughts, the meaning of the Leitfaden at A79 and the unity of cognition, (...) the two-steps-in-one-proof interpretation and categorial instantiation, categorial illusion, Strawson’s transcendental argument, the persistently perplexing question of the derivation of the categories, and the relation between apperception, objectivity, judgement, and idealism. -/- With regard to idealism in particular, the focus is on the metaphysical two-aspect interpretation and its problems, on the merits and demerits of the controversial phenomenalist reading of Kant’s idealism, and on the topic of subjectivism and epistemic humility. -/- In all of the aforementioned topics, the book presents wholly novel interpretations compared to the standard or mainstream interpretations.

review of Béatrice Longuenesse latest book on Kant and self-consciousness I, Me, Mine (Oxford 2017).

In the context of a critique of James Conant’s (2016) important new reading of the main argument of the Deduction, I present my current, most detailed interpretation of the well-known Leitfaden passage at A79, which in my view has been misinterpreted by a host of prominent readers. The Leitfaden passage is crucial to understanding the argument of, not just the so-called Metaphysical Deduction, but also the Transcendental Deduction. This new account expands and improves upon the account of the Leitfaden I (...) gave in Chap. 5 of Kant’s Deduction From Apperception. While I agree with the core of Conant’s critique of what he calls the ‘layer-cake’ reading of the Deduction argument, in this new account I make clearer my position on why the unity of judgement, in which concepts and intuitions are a priori synthetically unified, is wholly determined in virtue of the unity of apperception as the unitary function of the understanding, without this leading to a strong form of conceptualism such as that of Conant and others.
