Is practical reason a cognitive faculty? Do practical judgments make claims about a subject matter that are appropriately assessed in terms of their agreement with that subject matter? According to Kantians like Christine Korsgaard, the answer is no. To think otherwise is to conflate the theoretical and the practical, the epistemic and the ethical. I am not convinced. In this paper, I motivate my skepticism through examination of the very figure who inspires Korsgaard’s rejection of cognitivism: Kant. For as I (...) read him, Kant does not construe the distinction between theoretical and practical reason in terms of a distinction between cognitive and non-cognitive faculties but in terms of two distinct applications of a single faculty of reason, which is through-and-through cognitive. Thus, practical, no less than theoretical, reason cognizes a subject matter, and so practical, no less than theoretical, reason is straightforwardly subject to familiar epistemic standards of truth, warrant, and knowledge. Of course, even if I am right about Kant, this does not show that Korsgaard is wrong about reason; and I will offer no direct argument against her position here. Nonetheless, I believe that reflection on Kant’s true view, with its careful treatment of and respect for both the practicality and rationality of reason, should perhaps lead us to rethink what it means to be a rationalist in ethics.

Ask most philosophers for an example of a moral rationalist, and they will probably answer “Kant.” And no wonder. Kant’s first great work of moral philosophy, Groundwork of the Metaphysics of Morals, opens with a clarion call for rationalism, proclaiming the need to work out for once a pure moral philosophy, a metaphysics of morals. That this metaphysics includes the first principle of ethics, the moral law, is obvious. But what about the second principles, particular moral laws, such as duties (...) of truthfulness, beneficence, etc.? Are these principles metaphysical too? Many have thought not, since they make essential use of empirical and anthropological considerations. I argue otherwise; the second principles are metaphysical and this matters. I do this by taking seriously the metaphysics of the metaphysics of morals—more specifically, by understanding the metaphysics of morals alongside the metaphysics of nature. For, qua metaphysics, both employ a common two-stage methodology, the first stage of which is wholly a priori but the second stage of which is partly empirical. As I explain, appreciating this common methodology sheds new light on how the second principles are to be established, as well as on the reach of Kant’s rationalism. (shrink)

Traditionally, Kantian ethics has been thought hostile to agents' well-being. Recent commentators have rightly called this view into question, but they do not push their challenge far enough. For they leave in place a fundamental assumption on which the traditional view rests, viz., that happiness is all there is to well-being. This assumption is important, since, combined with Kant’s rationalism about morality and empiricism about happiness, it implies that morality and well-being are at best extrinsically related. Since morality can only (...) make our lives go well by making us happy, and since morality can only make us happy by influencing our sensibility, morality is not its own reward--not really. It is simply the condition for some separate benefit. Drawing on Kant’s underappreciated discussion of self-contentment, an intellectual analog of happiness, I reconstruct an alternative account of morality’s relation to well-being. Morality does make our lives go well--and so is its own reward--not because it makes us happy but because it makes us self-contented. (shrink)

According to rationalist conceptions of moral agency, the constitutive capacities of moral agency are rational capacities. So understood, rationalists are often thought to have a problem with feeling. For example, many believe that rationalists must reject the attractive Aristotelian thought that moral activity is by nature pleasant. I disagree. It is easy to go wrong here because it is easy to assume that pleasure is empirical rather than rational and so extrinsic rather than intrinsic to moral agency, rationalistically conceived. Drawing (...) on underappreciated elements of Kant’s moral psychology, I sketch an alternative form of rationalism, according to which moral activity is by nature pleasant because at least some pleasures are by nature rational.

According to many of its advocates, one of the main attractions of Kantian moral philosophy is its metaethical innocence. The most interesting argument for such innocence appeals to Kantians' rationalism. Roughly, if moral action is simply rational action, then we do not need to appeal to anything beyond rationality to certify moral judgment. I assess this argument by reflecting on (dis)analogies between moral and logical forms of rationalism. I conclude that the Kantian claim to metaethical innocence is overstated. Kantians cannot (...) avoid substantial metaethical commitments. Or if they can, it is not their rationalism that explains why this is so. (shrink)

I offer a qualified defence of Kant’s natural teleological argument, that is, his inference from the (un)naturalness of an act to its (im)morality. Though I reject many of Kant’s conclusions, I think the form of argument he uses to support these conclusions is not as wrong-headed as it might at first appear. I consider and answer two objections: first, that the argument is inconsistent with Kant’s moral rationalism; and second, that the argument is inconsistent with post-Kantian developments in science. I (...) argue that both objections rest on a common mistake, namely, the assumption that the account of (human) nature on which Kant’s argument relies is theoretical. On the contrary, the relevant account is practical: informed by science, but not determined by it. Once we appreciate the practical character of Kant’s naturalism, we can see not only that Kant can be a naturalist and a rationalist, but contemporary Kantians can be as well. (shrink)

My aim in this essay is to reorient our understanding of the Kantian ethical project, especially in relation to its assumed rivals. I do this by considering Kant's relation to eudaimonism, especially in its Aristotelian form. I argue for two points. First, once we understand what Kant and Aristotle mean by happiness, we can see that not only is it the case that, by Kant's lights, Aristotle is not a eudaimonist. We can also see that, by Aristotle's lights, Kant is (...) a eudaimonist. Second, we can see that this agreement on eudaimonism actually reflects a deeper, more fundamental agreement on the nature of ethics as a distinctively practical philosophy. This is an important result, not just for the history of moral philosophy but for moral philosophy as well. For it suggests that both Kantians and Aristotelians may well have more argumentative resources available to them than is commonly thought. (shrink)
