By taking into account some texts published between the first and the second edition of the Critique of Pure Reason that have been neglected by most of those who have dealt with the deduction of the categories, I argue that the core of the deduction is to be identified as the ‘almost single inference from the precisely determined definition of a judgment in general’, which Kant adumbrates in the Metaphysical Foundations in order to ‘make up for the deficiency’ of the (...) A-deduction. Whereas the first step of the B-deduction is an attempt to show that the manifold of an intuition belongs to the ‘necessary unity of self-consciousness’ by means of the synthesis of the understanding, the second step has the task of showing that the very same synthesis is responsible for the spatio-temporal unity of the manifold. Thus, Kant's ‘answer to Hume’ is that no spatio-temporal objects of experience at all are merely ‘given’, independently of the conceptual activities of the understanding. Against the established view I substantiate the claim that with this ‘almost single inference’ of the second proof step the distinction between judgments of perception and judgments of experience consequently vanished from Kant's thinking.

The Transcendental Deduction in the second edition of Kant’s Critique of Pure Reason is divided in two parts. Nevertheless, the role of the second half is not immediately clear. This article intends to examine the argument presented in the second half after clarifying its purpose. Based on this approach, we sustain an interpretation according to which Kant tries to establish the validity of categories for all intuition given through sensibility. This interpretation seeks to confirm a conceptual articulation among sensible intuitions (...) that is not regarded as a result of objective judgment. (shrink)

This thesis argues that Kant is able to maintain the distinctiveness of his position in opposition to Hume's naturalism (contrary to the arguments of R. A. Mall and L. W. Beck) without invoking premises which are question begging with regard to Hume's scepticism. The argument of Kant's Transcendental Deduction of the Categories, as presented in the second edition of the Critique of Pure Reason, is considered in relation to the two sets of criticism that have been levelled at it from (...) its publication up to the present day, both of which aim to demonstrate that synthetic a priori judgements are subjectively necessary but without objective validity. The first set of criticisms involves problems raised with regard to the status of transcendental arguments. The difficulties identified here (by B. Stroud, M. S. Gram, and others) are that the Deduction can either, at best, show that it is necessary for experience to be regarded in a certain way without demonstrating anything as to the nature of experience as such, or the argument is circular in that it begins by making assumptions regarding the nature of our experience. Alternatively, if the Deduction is taken to establish the objective nature of concepts via an analysis of the conditions under which it is possible for us to have some knowledge of ourselves, then incoherence is said to arise because this requires either an implausible reflective theory of consciousness (according to D. Henrich) or that we have knowledge of the subject-in-itself (as held by J. G. Fichte and other contemporaries of Kant). Through a consideration of both the historical and contemporary manifestations of these criticisms, the thesis advances an interpretation of the Deduction, with special attention paid to the role and nature of the subject, which does not fall prey to the alleged incoherence. As such, the thesis defends both the distinctiveness and legitimacy of transcendental philosophy. (shrink)
