To advance a successful reading of Kant's theory of motivation, his interpreter must have a carefully developed position on the relation between our rational and sensible capacities of mind. Unfortunately, many of Kant's commentators hold an untenably dualistic conception, understanding reason and sensibility to be necessarily conflicting aspects of human nature that saddle Kant with a rigoristic and fundamentally divided moral psychology. Against these interpreters, I argue for a reading that maintains a unified conception, claiming that we must think of (...) reason and sensibility as interdependent capacities, which stand to one another as form to matter. Our sensible nature thus does not stand opposed to reason; its fundamental character is determined by reason's activity. I take Kant's account of moral motivation and the feeling of respect to represent the lynchpin of this unified account. Against interpreters who would emphasize either the intellectual or affective nature of respect, I claim that it should be understood as the formal element of moral sensibility, the result of practical reason determining the capacity to feel and fundamentally transforming its character. To make this argument, I draw on Kant's account of sensibility in the Critique of Pure Reason, claiming that space, time, and respect for the moral law are analogous formal elements of sensibility.

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. (shrink)

Despite Kant’s lasting influence on philosophical accounts of moral motivation, many details of his own position remain elusive. In the Critique of Practical Reason, for example, Kant argues that our recognition of the moral law’s authority must elicit both painful and pleasurable feelings in us. On reflection, however, it is unclear how these effects could motivate us to act from duty. As a result, Kant’s theory of moral sensibility comes under a skeptical threat: the possibility of a morally motivating feeling (...) seems incoherent. My aim in this paper is to reconstruct Kant’s theory in a way that overcomes this threat. By way of conclusion, I show how my reconstruction brings a new perspective to a long-standing dispute over intellectualist and affectivist views of moral motivation. (shrink)

In the Critique of Practical Reason, Kant grounds his postulate for the immortality of the soul on the presupposed practical necessity of the will’s endless progress toward complete conformity with the moral law. Given the important role that this postulate plays in Kant’s ethical and political philosophy, it is hard to understand why it has received relatively little attention. It is even more surprising considering the attention given to his other postulates of practical reason: the existence of God and freedom. (...) The project of this paper is to examine Kant’s postulate of the immortality of the soul, examine critiques of this argument, and show why the argument succeeds in showing that belief in the moral law also obligates one to believe in the soul’s immortality.

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)

This paper develops an interpretation of what is essential to kant's doctrine of the highest good, Which defends it while also explaining why it is often rejected. While it is commonly viewed as a theological ideal in which happiness is proportioned to virtue, The paper gives an account in which neither feature appears. The highest good is best understood as a state of affairs to be achieved through human agency, Containing the moral perfection of all individuals and the satisfaction of (...) their permissible ends-I.E., One in which all act from the moral law and in doing so achieve their intended ends. The paper shows that the texts contain two distinct conceptions not distinguished by kant-Both a theological and a secular (political) notion. The standard objections apply to the theological, But the secular conception is consistent with kant's conception of moral conduct. Moreover, That the highest good is introduced as an end to be constructed out of the moral law indicates that the secular version is the essential notion. (shrink)

Kant’s postulate of the immortality of the soul has received strikingly little attention among Kant scholars, and only very few have regarded it positively. This is not surprising given the numerous problems associated with his argument. However, it is not the only argument for immortality that Kant offers in his critical philosophy. There is also a second argument that differs from the one furnished in the Second Critique and can be found both in the Critique of Pure Reason and later (...) texts from the 1790s. Kant also addresses here many of the problems that interpreters have found with his postulate of immortality in both earlier and later texts. This paper considers the main difficulties associated with the postulate and proposes a coherent interpretation of Kant’s argument. I show that despite the apparent change in his approach to immortality Kant did not in fact substantially alter his position during his critical period. (shrink)

Kant is clear that the concept of the 'highest good' involves both a demand, that we follow the moral law, as well as a promise, that happiness will be the outcome of being moral. The latter element of the highest good has troubled commentators, who tend to find it metaphysically extravagant, involving, as it does, belief in God and an afterlife. Furthermore, it seems to threaten the moral purity that Kant demands: that we obey the moral law for its own (...) sake, not out of interest in the consequences. Those commentators brave enough to tackle the issue look to the concept of the highest good either to add content to the moral law (Silber), or to provide rational motivation, in a way that does not violate moral purity (Beiser and Wood). I argue that such interpretations, although they may be plausible reconstructions, are unable to account for certain conceptual and textual problems. By placing Kant's thought against the background of medieval theology, I argue that the hope for the summum bonum is irreducibly important for Kant, even where its function is not that of providing the content or motivational force of the moral law. Kant is not only concerned with the shape of our duties and motivations, but the shape of the universe within which these emerge. (shrink)

Kant’s ethics conceives of rational beings as autonomous–capable of legislating the moral law, and of motivating themselves to act out of respect for that law. Kant’s ethics also includes a notion of the highest good, the union of virtue with happiness proportional to, and consequent on, virtue. According to Kant, morality sets forth the highest good as an object of the totality of all things good as ends. Much about Kant’s conception of the highest good is controversial. This paper focuses (...) on the apparent conflict between Kant’s claim that we are autonomous, and passages in which he seems to suggest that we require belief in the possibility of the highest good to motivate moral action. I distinguish three distinct versions of these problematic claims that seem to be present in Kant’s texts: that the highest good serves as (1) a motivational supplement to respect for the moral law, (2) a fundamental spring of right action, and (3) a condition of the bindingness of moral requirements. I argue that the texts are better interpreted to yield alternatives to (2) and (3) that do not conflict with our autonomy. I also argue that, properly understood, (1) does not conflict with our autonomy. In arguing for the last claim, I explore Kant’s notion of radical evil and its implications for human agency and virtue. (shrink)
