The paper is an interpretation and defense of Kant's conception of things in themselves as noumena, along the following lines. Noumena are transempirical realities. As such they have several important roles in Kant's critical philosophy (Section 1). Our theoretical faculties cannot obtain enough content for a conception of noumena that would assure their real possibility as objects, but can establish their merely formal logical possibility (Sections 2-3). Our practical reason, however, grounds belief in the real possibility of some noumena, and (...) even knowledge of the noumenal reality of a free will (Section 4). Section 5 defends Kant's conception of noumena as a good piece of philosophy, particularly with respect to its distinction between logical and real possibility. Are noumena numerically identical with experienced (phenomenal) objects? Kantian principles yield the answers that human selves are, God isn't, and it's harder to say about bodies (Section 6).

In the Metaphysical Foundations of Natural Science, Kant presents an argument for the centrality of <motion> to our concept <matter>. This argument has long been considered either irredeemably obscure or otherwise defective. In this paper I provide an interpretation which defends the argument’s validity and clarifies the sense in which it aims to show that <motion> is fundamental to our conception of matter.

This paper addresses the question of what we can legitimately say about things in themselves in Kant's critical doctrine. Many Kant scholars believe that Kant allows that things in themselves can be characterized through the unschematized or ‘pure’ concepts of our understanding such as ‘substance’ or ‘causality’. However, I show that on Kant's view things in themselves do not conform to the unschematized categories : the pure categories, like space and time, are merely subjective forms of finite, discursive cognition. I (...) then examine what this interpretation might entail for central aspects of Kant's system such as his doctrine of noumenal freedom. (shrink)

Kant’s published arguments for the non-spatiotemporality of things in themselves have not been well received. I argue that Kant has available to himself an argument for the non-spatiotemporality of things in themselves that is premised upon a disparity between the compositional structure of the intelligible world and the structure of space and time. I argue that Kant was unwaveringly committed to the premises of this argument throughout his career and that he was aware of their idealistic implications. I also argue (...) that this argument is consistent with Kant’s restrictive mature epistemology. If my argument is successful, then even if Kant’s published arguments for transcendental idealism fail, we need not regard his ambitious metaphysical project as a failure. (shrink)

ABSTRACTIf it seems unquestionable that C. I. Lewis is a Kantian in important respects, it is more difficult to determine what, if anything, is original about his Kantianism. For it might be argued that Lewis’ Kantianism simply reflects an approach to the a priori which was very common in the first half of the twentieth century, namely, the effort to make the a priori relative. In this paper, I will argue that Lewis’ Kantianism does present original features. The latter can (...) be detected by focusing on Lewis’ account of the method of philosophy in the first chapter of Mind and the World Order. In that context, Lewis argues that the method of philosophy should be reflective and critical. It will be my contention that this understanding of philosophy involves a therapeutic perspective, which bears important resemblances to Kant’s account of transcendental reflection in the Amphiboly of the Critique of Pure Reason. I will illustrate how this therapeutic application of reflection works in Lewis’ metaphysics. In... (shrink)
