<strong>A fascinating examination of delusional thinking and how it might benefit health, relationships, and wellbeing</strong>.Although reason and rationality are our friends in almost all contexts, in some cases people are better off putting reason aside. In a number of very important situations, we benefit by not seeing the world as it is, and by not behaving like logic-driven machines. Sometimes we know we aren't making sense, and yet we are compelled to act against reason; in other cases, our delusions are so much a part of normal human experience that we are unaware of them. As intelligent as we are, much of what has helped humans succeed as a species is not our prodigious brain power but something much more basic. <em>The Uses of Delusion </em>is about aspects of human nature that are not altogether rational but, nonetheless, help us achieve our social and personal goals. Psychologist Stuart Vyse presents a lively, accessible exploration of the psychological concepts behind "useful delusions", fleshing out how delusional thinking may play a role in love and relationships, illness and loss, and personality and behavior. Along the way Vyse draws on the work of William James, Daniel Kahneman, and Joan Didion - who wrote about her compelling belief that her husband, though deceased, would soon return to her. Throughout, Vyse strives to answer the question: why would some of our most illogical beliefs be as helpful as they are? The concluding chapter offers an explanation grounded in natural selection - the ability to fool ourselves, Vyse argues, has actually helped us to survive. In the final pages of <em>The Uses of Delusion</em>, Vyse offers suggestions for determining when reason should rule and when intuition and emotion should be allowed to take over.
