MOST of us feel an aversion to lying and believe that it always stands in need of justification. One expression of this is to say that there is a prima facie duty not to lie. Another is Sissela Bok's "Principle of Veracity" which holds that lying has an "initial negative weight" so that there is always a presumption against telling a particular lie. Still a third variation can be found in Arnold Isenberg's "constancy principle" which holds that what is inherently (...) bad in any lie is the same for all, constant from one lie to the next. While these sorts of view are plausible, the literature on lying provides little in the way of a specific account for the negative weight inherent in all lies--their common disvalue. What follows is proposed as such an account, one which should also help clarify why some lies are worse than others, why some are excusable and others justifiable. Without presuming to be exhaustive, the view offered maintains that there are at least two inherent negative components of all lies; further, each of these inherent disvalues disposes the liar toward a particular, contingent harm. The inherent disvalues and the harms they threaten collectively constitute sufficient grounds for the presumption against lying. (shrink)

Self-deception raises complex questions about the nature of belief and the structure of the human mind. In this book, Alfred Mele addresses four of the most critical of these questions: What is it to deceive oneself? How do we deceive ourselves? Why do we deceive ourselves? Is self-deception really possible? -/- Drawing on cutting-edge empirical research on everyday reasoning and biases, Mele takes issue with commonplace attempts to equate the processes of self-deception with those of stereotypical interpersonal deception. Such attempts, (...) he demonstrates, are fundamentally misguided, particularly in the assumption that self-deception is intentional. In their place, Mele proposes a compelling, empirically informed account of the motivational causes of biased beliefs. At the heart of this theory is an appreciation of how emotion and motivation may, without our knowing it, bias our assessment of evidence for beliefs. Highlighting motivation and emotion, Mele develops a pair of approaches for explaining the two forms of self-deception: the "straight" form, in which we believe what we want to be true, and the "twisted" form, in which we believe what we wish to be false. -/- Underlying Mele's work is an abiding interest in understanding and explaining the behavior of real human beings. The result is a comprehensive, elegant, empirically grounded theory of everyday self-deception that should engage philosophers and social scientists alike. (shrink)
