Like several prominent moral philosophers before him, such as St Augustine and St Thomas Aquinas, Kant held that it is never morally permissible to tell a lie. Although a great deal has been written on why and how he argued for this conclusion, comparatively little has been written on what, precisely, Kant considered a lie to be, and on how he differentiated between being truthful and being candid, between telling a lie and being reticent, and between telling a lie and (...) other forms of linguistic deception. That is to say, very little has been written on the scope of Kant's prohibition against lying. In this article I will argue that the scope of the prohibition against lying is narrower than it is commonly supposed to be. (shrink)

Kant’s essay ‘On a Supposed Right to Lie from Philanthropy’ claims that everyone has an unconditional duty of right not to lie under any circumstances. This claim creates a conflict within the doctrine of right because Kant also claims that each of us is under an unconditional duty of right to obey the positive law in force in the civil condition in all circumstances. In Kant’s specific example, truthfulness would violate the positive law because it would make the speaker an (...) accomplice to a crime. Since both duties flow from the requirement that we not act inconsistently with the possibility of rightful relations among humans, a juridical solution to the conflict must be possible. That solution is to recognize that lying in appropriate circumstances is akin to the use of force in self-defence or defence of a third party. (shrink)

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)

Critics often charge that Kantian ethics is implausibly rigoristic: that Kantianism recognizes a set of perfect duties, encapsulated in rules such as ‘don’t lie,’ ‘keep one’s promises,’ etc., and that these rules apply without exception. Though a number of Kantians have plausibly argued that Kantianism can acknowledge exceptions to perfect duties, this acknowledgment alone does not indicate how and when such exceptions ought to be made. This article critiques a recent attempt to motivate how such exceptions are to be made, (...) namely, the constitutive approach developed by Tamar Schapiro. I argue that the constitutive approach is vulnerable to the objection that it is too permissive, justifying many morally dubious exceptions to perfect duties. I conclude by briefly outlining an alternative ‘fine print’ approach to the rigorism objection that appears to avoid the objection leveled at Schapiro’s approach, focusing on how modifying the constituents of agents’ maxims can change the deontic status of an act of a generally impermissible kind.

Kant has traditionally been read as an excessively moralistic critic of lying in his ethics and politics. In response, recent scholars have noted that for Kant we have an ethical duty not to be com...
