#571: Laissez-Faire

In this book, Damasio argues that emotions are essential to rational thinking and normal social behavior. He challenges René Descartes' mind-body dualism by presenting case studies, particularly the famous case of Phineas Gage, to demonstrate how brain damage can affect decision-making and personality. Damasio introduces the 'somatic marker hypothesis,' which posits that emotions guide behavior and decision-making, and that rationality requires emotional input. The book is divided into three parts, exploring case studies, explanations for the effects of brain injuries, and testing the somatic marker hypothesis.
