In The Sources of Normativity Korsgaard introduces her conception of practical identities understood as the source of moral obligations. This conception forms a point of transition from Korsgaard’s theory of action to her solution to the problem of the authority of moral norms. In order to describe how universal categorical reasoning is compatible with the moral content of particular practical decisions, Korsgaard needs to show how our contingent practical identities can be reconciled with what she defines as the universally shared (...) identity that expresses our humanity. To make this reconciliation work, she devises an argument for the public shareability of reasons amended by her reinterpretation of the Kantian as if principle. I suggest that, in doing so, Korsgaard steps too far away from Kant’s architectonic approach to the question of why moral norms bind us, and that, consequently, the Korsgaardian reconciliation between the two kinds of identities, as it stands, cannot be accomplished.

According to the standard reading of Kant's formula of universal law (FUL), positive duties can be derived from FUL. In this article, I argue that the standard reading does not work. In the first section, I articulate FUL and what I mean by a positive duty. In the second section, I set out an intuitive version of the standard reading of FUL and argue that it does not work. In the third section, I set out a more rigorous version of (...) the standard reading of FUL and argue that even this more rigorous version does not work. (shrink)

The article defends three claims regarding the relation between the different formulas of the categorical imperative. On its prevailing reading, FUL gives different moral guidance than FH; left answered, this problem is an argument for adopting a competing perspective on FUL. The prohibitions and commands of the formulas should be taken to be extensionally the same; but FKE adds a dimension missing from the others, gained by uniting their perspectives, namely, bringing the variety of moral laws into systematic unity. The (...) grammatically ambiguous phrase inGMS, 4: 436.9–10 claims that FA alone unites the other formulas in itself. (shrink)

We can distinguish two kinds of moral universalization tests for practical principles. One requires that the universal practice of the principle, i.e., universal conformity to it by all agents in a given world, satisfies some condition. The other requires that conformity to the principle by any possible agent, in any situation and at any time, satisfies some condition. We can call these universal practice and universal applicability tests respectively. The logical distinction between these tests is rarely appreciated, and many philosophers (...) systematically confuse them with each other. In practice, UP tests are more frequently used to defend deontological norms, while UA tests are used to defend consequentialist norms. Both conceptual argument and practical examples of their applications will show that UA tests are decisively superior to UP tests for grounding moral norms, casting greater doubt upon deontological theories which rely upon the latter unless they can reformulate their arguments using some version of a UA test.

There has long been a suspicion that Kant's test for the universalizability of maxims can be easily subverted: instead of risking failing the test, design your maxim for any action whatsoever in a manner guaranteed to pass. This is the problem of maxim-fiddling. The present discussion of this problem has two theses: 1] That extant approaches to maxim-fiddling are not satisfactory;2] That a satisfactory response to maxim-fiddling can be articulated using Kantian resources, especially the first two formulations of the categorical (...) imperative. This approach to maxim-fiddling draws our attention to a Kantian notion of an offence against morality itself that has largely been overlooked. (shrink)

The conception of two kinds of practical identities, which Korsgaard introduces in the Sources of Normativity, helps her explain how universal categorical reasoning is compatible with the moral content of individual practical decisions. Based on this conception, she devises an interpretation of the Kantian as if principle amended by her argument for the public shareability of reasons. I suggest that, in doing so, Korsgaard steps too far away from Kant’s architectonic approach to the question of why moral norms bind us, (...) and that, as a result, the Korsgaardian explanation, as it stands, cannot be accomplished.

Given Kant's exceptionless moral prohibition on lying, one might suspect that he is committed to a similar prohibition on withholding diagnostic and prognostic information from patients. I confirm this suspicion by adapting arguments against therapeutic privilege from his arguments against lying. However, I show that all these arguments are importantly flawed and submit that they should be rejected. A more compelling Kantian take on informed consent and therapeutic privilege is achievable, I argue, by focusing on Kant's duty of beneficence, which (...) requires us to aim at furthering others’ ends. But I show that there are some cases in which furthering a patient's ends requires withholding material medical information from her. Although I concede that these cases are probably quite rare, I conclude that the best Kantian thinking agrees with that of therapeutic privilege's advocates. (shrink)
