Is it possible for me to believe what I know not to be the case? It certainly does not seem possible for me, at the same time, to be aware of the fact that a given proposition is true and yet believe that the proposition is false. Models of self?deception which have the implication that this is possible are usually described as ?paradoxical?. However, many philosophers believe that there are genuine cases of self?deception which non?paradoxical models of self?deception mirror and elucidate. In the present article the author considers what he takes to be the leading contenders among non?paradoxical (or seemingly non?paradoxical) models of self?deception. He concludes from his analysis that it is not clear that any of these models mirror actual cases of self?deception and that it is not even obvious that there are actual cases of self?deception to be mirrored.

Mele's modified definition of self-deception is consistent with evolutionary theory. Self-deception is most likely whenever ignorance confers (reproductive) advantage, namely, in impression management, deception, conformity, social norms, reproductive knowledge, and existential conflicts. Second-order self-deception (unawareness of unawareness) perpetuates self-deception and may be the reason for our misguided definitions.

What is it to deceive someone? And how is it possible to deceive oneself? Does self-deception require that people be taken in by a deceitful strategy that they know is deceitful? The literature is divided between those who argue that self-deception is intentional and those who argue that it is non-intentional. In this study, Annette Barnes offers a challenge to both the standard characterisation of other-deception and current characterizations of self-deception, examining the available explanations and exploring such questions as the self-deceiver's false consciousness, bias, and the irrationality and objectionability of self-deception. She arrives at a non-intentional account of self-deception that is deeper and more complete than alternative non-intentional accounts and avoids the reduction of self-deceptive belief to wishful belief.

The essence of a mental event such as self-deception lies in its function – its place in the life of an animal. But the function of self-deception corresponds to that of interpersonal deception. Therefore self-deception, contrary to Mele's thesis, is essentially isomorphic with interpersonal deception.

This response addresses seven main issues: (1) alleged evidence that in some instances of self-deception an individual simultaneously possesses “contradictory beliefs”; (2) whether garden-variety self-deception is intentional; (3) whether conditions that I claimed to be conceptually sufficient for self-deception are so; (4) significant similarities and differences between self-deception and interpersonal deception; (5) how instances of self-deception are to be explained, and the roles of motivation in explaining them; (6) differences among various kinds of self- deception; (7) whether a proper conception of self-deception implies that definitive ascriptions of self-deception to individuals are impossible.

This title gathers together essays on deception, self-deception, and the intersections of the two phenomena, from the leading thinkers on the subject.

Mele's study of philosophical and psychological theories of self-deception informatively links the conceptual and dynamic aspects of self-deception and explicates it without positing mutually inconsistent beliefs, such as those occurring in two-person deception. It is argued, however, that he does not do full justice to the dissociation characteristic of self-deception and does not sufficiently distinguish self-deception from self-caused deception.
