Kant criticizes the so-called ‘preformation’ hypothesis – a nativist account of the origin of the categories – at the end of the B-Deduction on the ground that it entails scepticism. I examine the historical context of Kant's criticism, and identify the targets as both Crusius and Leibniz. There are two claims argued for in this paper: first, that attending to the context of the opposition to certain forms of nativism affords a way of understanding Kant's commitment to the so-called ‘discursivity thesis’, by contrasting the possession conditions for the categories with those for innate ideas; secondly, it provides an insight with regard to Kant's understanding of the dialectic with scepticism. Kant's claim is that a certain explanatory lacuna that attaches to Humean empiricism can be seen to apply equally to any nativist theory. The lacuna concerns the explanation of the modal purport of a priori necessity, i.e. how it is that our consciousness can even distinguish contents that are represented as necessary features of objects.

This paper argues that, although no resistance or revolution is permitted in the Kantian state, very tyrannical regimes must not be obeyed because they do not qualify as states. The essay shows how a state ceases to be a state, argues that persons have a moral responsibility to judge about it and defends the compatibility of this with Kantian authority. The reconstructed Kantian view has implications for how we conceive authority and obligation. It calls for a morally demanding definition of the state and asserts that the primary personal responsibility is not to evaluate the morality of every single law but to evaluate the moral standing of the polity.

The notion of radical evil plays a more important role in Kant's moral theory than is typically recognized. In Religion Within the Limits of Mere Reason, radical evil is both an innate propensity and a morally imputable act – a paradoxical status that has prompted commentators to reject it as inconsistent with the rest of Kant's moral theory. In contrast, I argue that the notion of radical evil accounts for the beginning of moral responsibility in Kant's theory, since the act of attributing radical evil to one's freedom is an inauguration into the autonomous stance.

In the second edition Preface of Religion Within the Bounds of Bare Reason Kant responds to an anonymous review of the first edition. We present the first English translation of this obscure book review. Following our translation, we summarize the reviewer's main points and evaluate the adequacy of Kant's replies to five criticisms, including two replies that Kant provides in footnotes added in the second edition. A key issue is the reviewer's claim that Religion adopts an implied standpoint, described using transcendental terminology. Kant could have avoided much confusion surrounding Religion, had he taken this review more seriously. We therefore respond to three objections that Kant failed to address: how the Wille–Willkür distinction enables the propensity to evil to be viewed as coexisting with freedom of choice; how moral improvement is possible, even though the propensity to evil is necessary and universal; and how a ‘deed’ can be regarded as ‘noumenal’.

In a recent paper, Desmond Hogan aims to explain how Kant could have consistently held that noumenal affection is not only compatible with noumenal ignorance (the doctrine that we have no knowledge of things in themselves) but also with the claim that experience requires causal affection of human cognitive agents by things in themselves. Hogan's argument includes the premise that human cognitive agents have empirical knowledge of one another's actions. Hogan's argument fails because the premise that we have empirical knowledge of one another's actions is ambiguous. On one reading, the argument is valid but its conclusion trivial. On the other, it is unsound on Kant's own view.

There has been considerable recent debate about whether Kant's account of intuitions implies that their content is conceptual. This debate, however, has failed to make significant progress because of the absence of discussion, let alone consensus, as to the meaning of ‘content’ in this context. Here I try to move things forward by focusing on the kind of content associated with Frege's notion of ‘sense (Sinn)’, understood as a mode of presentation of some object or property. I argue, first, that Kant takes intuitions to have a content in this sense, and, secondly, that Kant clearly takes the content of intuitions, so understood, to be distinct in kind from that possessed by concepts. I then show how my account can respond to the most serious objections to previous non-conceptualist interpretations.
