Abstract

Utilitarian and deontological moral theories are often accused of failing to develop a convincing account of an agent's moral psychology, and so failing to provide an adequate theory of moral motivation that sustains their conception of morality as involving generally overriding moral duties. As a result of this apparent conflict between an agent's psychology and the demands of morality, many suggest making dramatic revisions to our conception of morality. I argue here that a more promising response is to examine where it is that morality fits into human psychology, and then build a theory of moral motivation that sustains ordinary conceptions of morality from this foundation. To do this, I start by looking at Hume's account of moral motivation, which is grounded in a rich and full moral psychology. In an attempt to show that his theory provides a promising foundation for a contemporary theory of moral motivation, I explore his account of acting from duty and develop a new interpretation of his theory of moral motivation that fits most consistently with both his criticism of other accounts and his more general claims about the virtue of justice. I argue that Hume offers an account of justice as being always valuable in virtue of being a necessary condition to the enjoyment of one's good character. I go on to suggest that pride in one's character, what we might now call personal integrity, commits each agent to acting with a sense of duty, and enables her to attain a level of social interaction that is necessary for her psychological development, yet not possible without a commitment to justice. After defending this interpretation of Hume, I extend this basic notion of personal integrity and demonstrate how this idea, combined with the workings of empathy and the psychological need for positive social interaction, generates a viable theory of moral motivation that maintains the common conception of morality as involving generally overriding moral duties while avoiding threats of alienation
