Abstract

As philosophical topics go, self-deception has something for everyone. It raises basic questions about the nature of belief and the relation of belief to thought, desire, and the will. It provokes further questions on such topics as reasoning, attention, self-knowledge, the unity of the self, intentional action, motivation, self-esteem, psychic defenses, the unconscious, personal character, and interpersonal relations. There are two basic questions about self-deception itself, which each take a familiar philosophical form: What is it? How is it possible? These questions have both an analytic and a psychological side. Is self-deception, as its name suggests, literally a case of lying to oneself? If not, how different can it be from other-deception and still deserve its name? Psychologically, what processes does self-deception involve and how is it motivated?
