"Rationality: Contexts and Constraints" is an interdisciplinary reappraisal of the nature of rationality. In method, it is pluralistic, drawing upon the analytic approaches of philosophy, linguistics, neuroscience, and more. These methods guide exploration of the intersection between traditional scholarship and cutting-edge philosophical or scientific research. In this way, the book contributes to development of a suitably revised, comprehensive understanding of rationality, one that befits the 21st century, one that is adequately informed by recent investigations of science, pathology, non-human thought, emotion, (...) and even enigmatic Chinese texts that might previously have seemed to be expressions of irrationalism. Addresses recent challenges and Identifies a direction for future research on rationalityInvestigates the relationship between rationality and mental disorders, such as delusion and depressionAssesses reasoning in artificial intelligence and nonhuman animalsReflects on ancient Chinese Philosophy and possible cultural differences in human psychology Employs philosophical reflection, along with linguistic, probabilistic, and logical techniques.

In this paper I discuss the scientific respectability of delusion as a psychiatric category. First, I present the essentialist objection to the natural kindhood of psychiatric categories, as well as non-essentialism about natural kinds as a response to that objection. Second, I present a nuanced classification of kinds of kinds. Third, drawing on the claim that the attribution of delusion relies on a folk psychological underpinning, I present the mind-dependence objection to the natural kind status of delusion. Finally, I argue (...) that even if delusion as a generic kind stands little chance of being vindicated as a non-essentialist natural kind, we stand to gain from a natural kind methodology regarding subtypes of delusion for which there is evidence of genuine causal signatures and mechanisms.

Jennifer Radden argues that delusions play an important role in modernist epistemology, which is preoccupied with the justification and evaluation of beliefs. Another theme running through the book is the importance of culture for attribution of delusion. Beliefs that look delusional will not be treated as pathological if they are expressions of religious views or other culturally acceptable forms of life. It is hard to see why cultural acceptability should play a role in the modernist project of justification. I suggest (...) that we think less about a philosophical project of justification and turn our attention instead to commonsense judgements of the circumstances in which we see a belief as evidence of underlying pathology. I discuss cases in which unjustified beliefs are nonetheless treated as phenomena that are consistent with our views of how healthy human beings act, and suggest that alongside folk psychology we should acknowledge a folk epistemology that embraces such instances. I suggest that delusions are beliefs that folk epistemology treats as inexplicable, and that this approach solves some of the puzzles that Radden identifies as growing out of the modernist epistemic project.

At the core of the sense of agency for self-produced action is the sense that I, and not some other agent, am producing and directing those actions. While there is an ever-expanding body of empirical research investigating the sense of agency for bodily action, there has, to date, been little empirical investigation of the sense of agency for thought. The present study uses the novel Mind-to-Mind paradigm, in which the agentive source of a target thought is ambiguous, to measure misattributions (...) of agency. Seventy-two percent of participants made at least one misattribution of agency during a 5-min trial. Misattributions were significantly more frequent when the target thought was an arousing negative thought as compared to a neutral control. The findings establish a novel protocol for measuring the sense of agency for thought, and suggest that both contextual factors and emotional experience play a role in its generation. (shrink)

My aim in this paper is to consider the question ‘Why is belief in God not a delusion?’. In the first half of the paper, I distinguish two kinds of religious belief: institutional and personal religious belief. I then review how cognitive science accounts for cultural processes in the acquisition and transmission of institutional religious beliefs. In the second half of the paper, I present the clinical definition of delusion and underline the fact that it exempts cultural beliefs from clinical (...) diagnosis. Finally, I review cognitive models of the intuitive attribution of mental disorders and how they support cultural exemption. Through the comparison of the models of cultural acquisition of religious beliefs and of cultural exemption in the attribution of delusion I intend to make it clear that we can provide an answer to our motivating question: even though some institutional religious beliefs may seem as strange as the most florid delusions, humans can readily recognize that they are not the product of mental dysfunction due to the fact that their acquisition and transmission is embedded within a cultural context.
