the importance of feelings


TechnologyReview | For decades, biologists spurned emotion and feeling as uninteresting. But Antonio Damasio demonstrated that they were central to the life-regulating processes of almost all living creatures.

Damasio’s essential insight is that feelings are “mental experiences of body states,” which arise as the brain interprets emotions, themselves physical states arising from the body’s responses to external stimuli. (The order of such events is: I am threatened, experience fear, and feel horror.) He has suggested that consciousness, whether the primitive “core consciousness” of animals or the “extended” self-conception of humans, requiring autobiographical memory, emerges from emotions and feelings.

His insight, dating back to the early 1990s, stemmed from the clinical study of brain lesions in patients unable to make good decisions because their emotions were impaired, but whose reason was otherwise unaffected—research made possible by the neuroanatomical studies of his wife and frequent coauthor, Hanna Damasio. Their work has always depended on advances in technology. More recently, tools such as functional neuroimaging, which measures the relationship between mental processes and activity in parts of the brain, have complemented the Damasios’ use of neuroanatomy.

A professor of neuroscience at the University of Southern California, Damasio has written four artful books that explain his research to a broader audience and relate its discoveries to the abiding concerns of philosophy. He believes that neurobiological research has a distinctly philosophical purpose: “The scientist’s voice need not be the mere record of life as it is,” he wrote in a book on ­Descartes. “If only we want it, deeper knowledge of brain and mind will help achieve … happiness.”
Antonio Damasio talked with Jason Pontin, the editor in chief of MIT Technology Review.
