What is wisdom? It seems easier to recognize than to define--a question for the realm of philosophers. But in recent decades, psychologists and neuroscientists have undertaken the empirical study of wisdom, locating brain activity that corresponds to traits like moral judgment, emotional regulation, and compassion. In his new book, Stephen Hall looks at the science behind wisdom and how it pertains to traditional interpretations. He finds associations between wisdom and adversity, and that in some cases, wisdom does come with age.
