Kantian defenders of suicide for the soon-to-be demented claim that killing oneself would protect rather than violate a person’s inherent worth. The loss of cognitive functions reduces someone to a lower moral status, so they believe that suicide is a way of preserving or preventing the loss of dignity. I argue that they misinterpret Kant’s examples and fail to appreciate the reasons behind his absolute prohibition on suicide. Although Kant says that one may have to sacrifice one’s life to fulfill (...) a moral duty, suicide is not morally equivalent to self-sacrifice because it involves treating oneself merely as a means. Furthermore, people facing the onset of dementia would not protect their dignity by killing themselves while they are still rational and would not avoid a demeaning existence. (shrink)

Kant’s argument against suicide is widely dismissed by scholars and often avoided by teachers because it is deemed inconsistent with Kant’s moral philosophy. This paper attempts to show a way to make sense of Kant’s injunction against suicide that is consistent with his moral system. One of the strategies adopted in order to accomplish my goal is a de-secularization of Kant’s ethics. I argue that all actions of self-killing (or suicide) are morally impermissible because they are inconsistent with God’s established (...) nature and order. It is argued that the existence of God as the locus of moral value and duty in Kant’s moral system, and not belief in God, can explain the consistency of Kant’s injunction against suicide. A synergistic view is offered, which rests on three arguments: First, suicide goes against God’s authority. Second, suicide is inconsistent with our self-perpetuating nature. Third, suicide goes against the rational will. (shrink)
