Two of the most basic questions regarding self-deception remain unsettled: What do self-deceivers want? What do self-deceivers get? I argue that self-deceivers are motivated by a desire to believe. However, in significant contrast with Alfred Mele’s account of self-deception, I argue that self-deceivers do not satisfy this desire. Instead, the end-state of self-deception is a false higher-order belief. This shows all self-deception to be a failure of self-knowledge.

From an evolutionary standpoint, a default presumption is that true beliefs are adaptive and misbeliefs maladaptive. But if humans are biologically engineered to appraise the world accurately and to form true beliefs, how are we to explain the routine exceptions to this rule? How can we account for mistaken beliefs, bizarre delusions, and instances of self-deception? We explore this question in some detail. We begin by articulating a distinction between two general types of misbelief: those resulting from a breakdown in (...) the normal functioning of the belief formation system (e.g., delusions) and those arising in the normal course of that system's operations (e.g., beliefs based on incomplete or inaccurate information). The former are instances of biological dysfunction or pathology, reflecting “culpable” limitations of evolutionary design. Although the latter category includes undesirable (but tolerable) by-products of “forgivably” limited design, our quarry is a contentious subclass of this category: misbeliefs best conceived as design features. Such misbeliefs, unlike occasional lucky falsehoods, would have been systematically adaptive in the evolutionary past. Such misbeliefs, furthermore, would not be reducible to judicious – but doxastically1noncommittal – action policies. Finally, such misbeliefs would have been adaptive in themselves, constituting more than mere by-products of adaptively biased misbelief-producing systems. We explore a range of potential candidates for evolved misbelief, and conclude that, of those surveyed, onlypositive illusionsmeet our criteria. (shrink)

Jon Elster has written a comprehensive, wide-ranging book on the emotions in which he considers the full range of theoretical approaches. Drawing on history, literature, philosophy and psychology, Elster presents a complete account of the role of the emotions in human behaviour. While acknowledging the importance of neurophysiology and laboratory experiment for the study of emotions, Elster argues that the serious student of the emotions can learn more from the great thinkers and writers of the past, from Aristotle to Jane (...) Austen. He attaches particular importance to the work of the French moralists, notably La Rochefoucauld, who demonstrated the way esteem and self-esteem shape human motivation. The book also maintains a running dialogue with economists and rational-choice theorists. Combining methodological and theoretical arguments with empirical case-studies and written with Elster's customary verve and economy, this book has great cross-disciplinary appeal. (shrink)
