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).

Kant once wrote, “Many historians of philosophy... let the philosophers speak mere nonsense.... They cannot see beyond what the philosophers actually said to what they really meant to say.’ Rae Langton begins her book with this quotation. She concludes it, after a final pithy summary of the position that she attributes to Kant, with the comment, “That, it seems to me, is what Kant said, and meant to say”. In between are some two hundred pages of admirably clear, tightly argued (...) exegesis, supplemented by detailed references, in which she offers what the dust jacket blurb fairly describes as “a new interpretation and defence of Kant’s doctrine of things in themselves.” This is an extremely engaging and thought-provoking book. I am pleased to recommend it. (shrink)

I provide a sympathetic reconstruction of Kant’s motivation for endorsing incompatibilism about human freedom. On my interpretation, Kant holds that if all the determining grounds of our actions were subject to natural necessity, we would never be free to respect or defy laws of practical reason, and for Kant such freedom is a condition for the possibility that our actions are governed by categorical imperatives. I argue that his view rests on a gripping construal of the rational imperfection that afflicts (...) the human will. (shrink)

It is standardly assumed that, in Kant, “free agency” is identical to moral agency and requires the will or practical reason. Likewise, it is often held that the concept of “spontaneity” that Kant uses in his theoretical philosophy is very different from, and much thinner than, his idea of practical spontaneity. In this paper I argue for the contrary view: Kant has a rich theory of doxastic free agency, and the spontaneity in empirical thought (which culminates in judgments of experience) (...) is essentially the same sort of spontaneity found in the practical use of reason. Accordingly, the faculties of understanding and practical reason both possess genuine autonomy. (shrink)

I propose a new way of understanding Kant’s doctrine of freedom. My reading seeks to combine features of two popular opposed lines of interpretation, namely, of metaphysical and anti-metaphysical readings. I defend the view that Kant’s idealist attempt to ‘save’ human freedom involves substantive metaphysical commitments. However, I show that this interpretation can fruitfully integrate important insights that are standardly associated with deflationary readings: first, the idea that for Kant freedom and natural necessity can be ascribed to one and the (...) same human being; and second, the idea that for Kant the belief in freedom and the belief in natural necessity belong to two different standpoints.

In the transcendental aesthetic of the Critique of Pure Reason, Kant claims that space and time are neither things in themselves nor properties of things in themselves but mere subjective forms of our sensible experience. Call this the Subjectivity Thesis. The striking conclusion follows an analysis of the representations of space and time. Kant argues that the two representations function as a priori conditions of experience, and are singular "intuitions" rather than general concepts. He also contends that the representations underwrite (...) some non-trivial a priori cognition of the objects of sensible experience. The Subjectivity Thesis is then presented as an immediate consequence: Space represents no property at all of any things in themselves nor any relation of them to each other. . . . For neither absolute nor relative determinations can be intuited prior to the existence of the things to which they pertain, thus [neither] can be intuited a priori. Time is not something which exists of itself, or which inheres in things as an objective determination. . . . [Were it] a determination or order inhering in things themselves, it could not precede the objects as their condition, and be known and intuited a priori by means of synthetic propositions. Kant's argument for the Subjectivity Thesis seems to have the following structure: * No absolute or relational features of things in themselves can be cognized a priori. (shrink)
