It is commonly thought that the distinction between subjectively valid judgements of perception and objectively valid judgements of experience in the Prolegomena is not consistent with the account of judgement Kant offers in the B Deduction, according to which a judgement is ‘nothing other than the way to bring given cognitions to the objective unity of apperception’. Contrary to this view, I argue that the Prolegomena distinction maps closely onto that drawn between the mathematical and dynamical principles in the System of Principles: Kant’s account of the Prolegomena distinction strongly suggests that it is the Analogies of Experience that make it possible for judgements of perception to give rise to judgements of experience. This means that judgements of perception are objectively valid with regard to the quantity and quality of objects, and subjectively valid with regard to the relation they posit between objects. If that is the case, then the notion of a judgement of perception is consistent with the B Deduction account of judgement.

For Kant, ‘wish’ is a technical term denoting a strange species of desire. It is an instance in which someone wills something that she simultaneously knows she cannot bring about. As a result, it is, in one sense, antithetical to morality, which deals with ‘ought implies can’. I will argue that Kant re-evaluated wishing as (to some extent) causally efficacious and, further, of moral relevance. This re-evaluation has not been discussed in the literature, yet has been lurking in plain sight in a subtle shift in two versions of a footnote from the Critique of the Power of Judgement.

In this article, I assess three contemporary criticisms levelled at Kant’s theory of evil in order to evaluate whether his theory can be saved. Critics argue that Kant does not adequately distinguish between evil and mundane wrongdoing, making his use of the term ‘evil’ emotional hyperbole; by defining evil as the subordination of the moral law to self-love his analysis is seemingly overly simplistic and empirically false; and by focusing solely on the moral character of the perpetrator of evil, Kant’s theory apparently ignores the most salient aspect of evil – the suffering of victims. While I will not claim that Kant provides us with a fully adequate theory of evil, I respond to each of these criticisms and conclude that Kant’s theory can still provide significant insight into both the nature of evil and the moral psychology of perpetrators of evil.

Kant’s accounts of moral education, appraisal respect and gratitude each depend on the assumption that human beings see and judge each other’s actions to be morally good. This assumption appears to stand in tension with the Opacity Thesis, Kant’s claim that we can never know if an action is morally good. This paper examines Kant’s discussion of moral illusion to relieve this tension. It is argued that we are required to uphold moral illusion, i.e. to represent others’ actions to be morally good (while knowing that we may be mistaken), due to the duty of beneficence for others’ moral well-being.

One way of understanding Kant’s views about moral emotions is the cultivation view. On this view, emotions play a role in Kantian morality provided they are properly cultivated. I evince a sceptical position about the cultivation view. First, I show that the textual evidence in support of cultivation is ambiguous. I then provide an account of emotions in Kant’s theory that explains both his positive and negative views about them. Emotions capture our attention such that they both disrupt the mind’s composure and serve as a surrogate for reason. As such, Kant cannot recommend that we cultivate our emotions.
