This article provides a critical discussion of the problems raised by Kant’s characterization of reason as having ‘needs’ and ‘interests’. The first part presents two examples of arguments in which this conative characterization of reason plays a crucial role. The rest of the article consists of a discussion of four different interpretations of Kant's talk of reason as having needs and interests. Having identified a number of problems with literal interpretations of the conative characterization of reason, I examine whether a (...) metaphorical reading, suggested by several commentators, can solve these problems. I argue that it is impossible to regard the conative terms in which Kant describes reason as merely decorative metaphors, and that they are better understood as cases of ‛symbolic exhibition' in Kant's own sense.

Kant claims that the concept of the highest good, the idea of happiness in proportion to virtue, is grounded in the moral law. But this claim has often been challenged. How can Kant justify including happiness in the highest good? Why should only the virtuous be worthy of happiness? This paper argues that when the moral law is interpreted as the criterion for valid application of the concept of the good, the concept of the highest good does indeed follow from (...) the moral law. It also argues that the duty to promote the highest good harmonizes with other duties. (shrink)

In his critical works of the 1780's, Kant claims, seemingly inconsistently, that (1) theoretical and practical reason are one and the same reason, applied differently, (2) that he still needs to show that they are, and (3) that theoretical and practical reason are united. I first argue that current interpretations of Kant's doctrine of the unity of reason are insufficient. But rather than concluding that Kant’s doctrine becomes coherent only in the Critique of Judgment, I show that the three statements (...) are compatible, providing a new and more coherent account of Kant's 1780's doctrine of the unity of reason.

This paper explains a way of understanding Kant's proof of God's existence in the Critique of Practical Reason that has hitherto gone unnoticed and argues that this interpretation possesses several advantages over its rivals. By first looking at examples where Kant indicates the role that faith plays in moral life and then reconstructing the proof of the second Critique with this in view, I argue that, for Kant, we must adopt a certain conception of the highest good, and so also (...) must choose to believe in the kind of God that can make it possible, because this is essentially a way of actively striving for virtue. One advantage of this interpretation, I argue, is that it is able to make sense of the strong link Kant draws between morality and religion. (shrink)
