Kant on Lying in Extreme Situations

A crucial issue in normative ethics concerns the morality of lying. Kant defends the view that the duty to not lie does not allow for any exceptions in practical judgments: it never is a person’s right or duty to lie. Many people abhor this view. Kantians have tried to make sense of Kant’s view (and save Kantian moral philosophy) by suggesting Kantian interpretations that are less strict. I reject the attempts to nuance the strictness of Kant’s view. I break new ground by arguing that Kant’s view is best made sense of by taking his strict stance seriously. I focus on his doctrine of virtue account against lying. Kant is not always strict on the interpretation of duties. As regards other duties he does leave (limited) room for exceptions. The strictness of the duty to not lie therefore is a special case intrinsically connected to key aspects of his fundamental philosophy. My explanation of the doctrine of virtue account starts out by focusing on the inner lie. For Kant each and every inner lie is problematic because being truthful is a condition and an integral part of the moral Denkungsart; i. e., way virtue manifests itself in the empirical world. Hence, an inner lie must be interpreted as the destruction of freedom and personhood. Kant’s doctrine of virtue view on the inner lie also implies a strict view on the outer lie. Developing this implication requires the analysis of Kant’s view on human self-knowledge and their propensity to evil.
