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

To many readers, it has seemed that Kant's discussion of the relation between practical and transcendental freedom in the Transcendental Dialectic is inconsistent with his discussion of the same relation in the Canon of Pure Reason. In this paper I argue for a novel way of preserving the consistency of Kant's view: in both the Dialectic and the Canon, 'transcendental freedom' requires the absence of determination by all natural causes, whereas 'practical freedom' requires the absence of determination by, specifically, sensuous incentives. However, I argue that the defense of freedom presented in the Canon is abandoned by Kant in the Groundwork when he first develops his conception of the absolute purity of moral motivation.

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.

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.

I attempt to answer the question of what Aristotle's criteria for 'being a substance' are in the Categories. On the basis of close textual analysis, I argue that subjecthood, conceived in a certain way, is the criterion that explains why both concrete objects and substance universals must be regarded as substances. It also explains the substantial primacy of concrete objects. But subjecthood can only function as such a criterion if both the subjecthood of concrete objects and the subjecthood of substance universals can be understood as philosophically significant phenomena. By drawing on Aristotle's essentialism, I argue that such an understanding is possible: the subjecthood of substance universals cannot simply be reduced to that of primary substances. Primary and secondary substances mutually depend on each other for exercising their capacities to function as subjects. Thus, subjecthood can be regarded as a philosophically informative criterion for substancehood in the Categories

Kant's doctrine of the radical evil in human nature invites at least two serious worries: first, it is unclear how Kant could establish the claim that all human beings adopt an evil maxim; second, this claim seems to conflict with central features of Kant's doctrine of freedom. I argue, via criticisms of various charitable interpretations, that these problems are indeed insuperable if we read Kant as trying to establish that all human beings are evil as a matter of fact. I then develop an alternative reading that avoids these problems. On my reading, Kant transforms the complaint that humans are evil into a prescriptive regulative principle. Although we cannot know whether all human beings really are evil, we ought to presuppose “inextirpable” human evil in the context of moral “ascetic”, the practical field that answers to the duty of moral self-perfection and that aims at the development of virtue.

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.

Although Kant is often considered the founding father of the controversial principle ‘Ought Implies Can’ (OIC), it is not at all clear how Kant himself understands and defends this principle. This essay provides a substained interpretation of Kant's views on OIC. I argue that Kant endorses two versions of OIC: a version that is concerned with our physical capacities, and a version that posits a link between moral obligation and a volitional power of choice. I show that although there are important senses in which Kant's conception of OIC differs from the way in which OIC is discussed in recent philosophy, his account raises important issues for contemporary theory: for instance, it highlights the extent to which acceptance or rejection of OIC reflects convictions about the sources of normativity.
