Abstract

My aim in this work is to consider Kant's ethical theory against the background of the main traditions in ethics which Kant opposed, especially ethical empiricism. I argue that the central issue that divided Kant and the opposed traditions concerns moral motivation. As Kant characterized ethical empiricism, and in general all opposed ethical theories, such theories adopted an Aristotelian view of human motivation according to which all action is based on desires. Kant argued that such ethical theories did not allow for the possibility of moral action--action based on purely rational motives, independent of desires. Kant thus rejected the Aristotelian view as adequate to explain the possibility of moral motivation and constructed an alternative view. I maintain that Kant wanted to construct a view according to which motivation is "internal to" moral reasons, as the empiricists maintained, yet such reasons are independent of human desire, i.e., "objective," as the rationalists maintained. I call this view of motivation, Kant's 'rational internalism.' ;My work is comprised of an introduction, eight chapters and a conclusion. Chapter 1 concerns the central question of Kant's ethical works: "How is morality possible?" which I claim should be read as a question about the possibility of moral motivation. In Chapters 2 and 3, I investigate empiricism in ethics, and in particular, the ethical views of Hobbes, Hutcheson and Hume. Chapters 4 through 7 contain my analysis of Kant's central criticism of ethical empiricism , and in Chapter 8 I present Kant's theory of moral motivation.
