We lie to ourselves every day: about how well we drive, how much we're enjoying ourselves - even how good looking we are. In this ground-breaking book, Robert Trivers examines not only how we self-deceive, but also why, taking fascinating examples from aviation disasters, con artists, sexual betrayals and conflicts within families. Revealing, provocative and witty, Deceit and Self-Deception is one of the most vital books written this century, and will make you rethink everything that you think you know. 'Original and important . . . remarkable, thick with ideas.' Financial Times 'One of the great thinkers in the history of Western thought.' Steven Pinker 'A swift tour of links between deception and evolutionary progress . . . fascinating.' Economist 'I devoured it from cover to cover . . . exhilarating.' Guardian 'A powerful book . . . essential for anyone who wants to try to counter their own unconscious biases.' Independent

Explores the author's theorized evolutionary basis for self-deception, which he says is tied to group conflict, courtship, neurophysiology, and immunology, but can be negated by awareness of it and its results.

This book systematically explores the moral issues surrounding self-deception. While many articles and books have been written on the concept of self-deception in recent years, Martin's gives much greater emphasis to self-deception as a significant topic for both ethical theory and applied ethics. "Self-deception is . . . perplexing from a moral point of view. It seems tailor-made to camouflage and foster immorality. . . . Does all self-deception involve some guilt, and is it among the most abhorrent evils. as some moralists and theologians have charged? Or is it only wrong sometimes, such as when it has bad consequences? Could it on occasion be permissible or even desirable to deceive ourselves, just as we are sometimes justified in deceiving other people? Are self-deceivers perhaps more like innocent victims than perpetrators of deceit, and as such deserving of compassion and help? Or, paradoxically, are they best viewed with ambivalence: culpable as deceivers and simultaneously innocent as victims of deception?" (from the introduction) Martin develops a conception of self-deception as the purposeful evasion of acknowledging to oneself truths or one's view of truth. He details a systematic framework for understanding the main moral perspectives and traditions concerning self-deception that have emerged in western philosophy. In so doing, he clarifies related concepts like sincerity, authenticity, honesty, hypocrisy, weakness of will, and self-understanding. Ranging across traditions both philosophical (Kant, Kierkegaard, and Sartre) and non-philosophical (Freud, Eugene O'Neill, and Henrik Ibsen), Martin shows why self-deception is as morally complex as any other major form of behavior. The appeal of this book is broad. The volume will challenge professional philosophers and psychologists, yet it is organized and written to be accessible to students in courses on ethics, philosophy of mind, and philosophy of literature. Martin's numerous literary examples should also interest literary critics.

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 nonintentional. In this study, Annette Barnes offers a challenge to both the standard characterization of the deception of others 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 of self-deception.

Defining lies as statements that are intended to deceive, this book considers the contexts in which people tell lies, how they are detected and sometimes exposed, and the consequences for the liars themselves, their dupes, and the wider society. The author provides examples from a number of cultures with distinctive religious and ethical traditions, and delineates domains where lying is the norm, domains that are ambiguous and the one domain (science) that requires truthtelling. He refers to experimental studies on children that show how, at an early age, they acquire the capactiy to lie and learn when it is appropriate to do so. He reviews how lying has been evaluated by moralists, examines why we do not regard novels as lies and relates the human capacity to lie to deceit among other animal species. He concludes that although there are, in all societies, good pragmatic reasons for not lying all the time, there are also strong reasons for lying some of the time.

Whether it's in a cockpit at takeoff or the planning of an offensive war, a romantic relationship or a dispute at the office, there are many opportunities to lie and self-deceive -- but deceit and self-deception carry the costs of being alienated from reality and can lead to disaster. So why does deception play such a prominent role in our everyday lives? In short, why do we deceive? In his bold new work, prominent biological theorist Robert Trivers unflinchingly argues that self-deception evolved in the service of deceit -- the better to fool others. We do it for biological reasons -- in order to help us survive and procreate. From viruses mimicking host behavior to humans misremembering (sometimes intentionally) the details of a quarrel, science has proven that the deceptive one can always outwit the masses. But we undertake this deception at our own peril. Trivers has written an ambitious investigation into the evolutionary logic of lying and the costs of leaving it unchecked.
