Humans have long struggled to explain the trait that makes us human: self awareness. Ancient Greeks and Christian theologians posited a soul separate from a body. A long line of philosophers have argued that we’re defined by our thinking human minds, distinct and higher than our physical selves. Scientists today see evidence of something like minds and cultures in social animals, but they still seek to explain why human consciousness rises to become knowledge of a self, why we have been able to create such complex identities and cultures. How did we come to be our selves? Neuroscientist Antonio Damasio, director of the USC Brain and Creativity Institute and author of Self Comes to Mind: Constructing the Conscious Brain, visited Zócalo to argue against the long-standing idea that consciousness is somehow separate from the body, presenting compelling new scientific evidence that consciousness is in fact a biological process created by living organisms.
