Although a common clinical phenomenon, delusions are difficult to explain and have a problematic conceptual status. Advances in understanding delusions have come from studies which involve detailed investigation of particular types of delusion. Some of this work is summarised, with the Capgras and Cotard delusions as specific examples. These are used to high-highlight questions for which there is the potential for fruitful dialogue with philosophers. Such questions include the criteria for deciding that a statement represents a belief, the extent to (...) which we integrate our beliefs into a coherent web, and the nature and limits of human rationality.

Circumscribed delusional beliefs can follow brain injury. We suggest that these involve anomalous perceptual experiences created by a deficit to the person's perceptual system, and misinterpretation of these experiences due to biased reasoning. We use the Capgras delusion (the claim that one or more of one's close relatives has been replaced by an exact replica or impostor) to illustrate this argument. Our account maintains that people voicing this delusion suffer an impairment that leads to faces being perceived as drained of (...) their normal affective significance, and an additional reasoning bias that leads them to put greater weight on forming beliefs that are observationally adequate rather than beliefs that are a conservative extension of their existing stock. We show how this position can integrate issues involved in the philosophy and psychology of belief, and examine the scope for mutually beneficial interaction. (shrink)

In instances of "twisted" self-deception, people deceive themselves into believing things that they do not want to be true. In this, twisted self-deception differs markedly from the "straight" variety that has dominated the philosophical and psychological literature on self-deception. Drawing partly upon empirical literature, I develop a trio of approaches to explaining twisted self-deception: a motivation-centered approach; an emotion-centered approach; and a hybrid approach featuring both motivation and emotion. My aim is to display our resources for exploring and explaining twisted (...) self-deception and to show that promising approaches are consistent with a plausible position on straight self-deception.

According to a traditional view of self-deception, the phenomenon is an intrapersonal analogue of stereotypical interpersonal deception. In the latter case, deceivers intentionally deceive others into believing something, p , and there is a time at which the deceivers believe that p is false while their victims falsely believe that p is true. If self-deception is properly understood on this model, self-deceivers intentionally deceive themselves into believing something, p , and there is a time at which they believe that p (...) is false while also believing that p is true.

This major volume of original essays maps the place of emotion in human nature, through a discussion of the relation between consciousness and body; by analysing the importance of emotion for human agency by pointing to the ways in which practical rationality may be enhanced, as well as hindered, by emotions; and by exploring questions of value in making sense of emotions at a political, ethical and personal level. Leading researchers in the field reflect on the nature of human feelings, (...) how and why we understand what other people feel, and the way in which our values become involved in specific emotional phenomena, such as guilt, fear, shame, amusement, or love. This collection addresses important questions in the philosophy of mind and comments on the implications of research in biology, cognitive psychology, psychoanalysis, and narrative theory for the philosophical understanding of emotions.
