Why can’t we all just get along?  And conversely, why do we sometimes get along so well, building cathedrals, inventing Democracy, symphonies, and stuff that that?  According to my guest today, the answer is as old as life itself. In the behaviors of the most ancient forms of bacteria, single-celled organisms without a nucleus, we can see the seeds of civilization as we know it, for better and for worse. They form collectives. They go to war. The key is homeostasis—the imperative of all life to avoid harm and seek to flourish. I’m delighted to be speaking today with neuroscientist and philosopher Antonio Damasio. He heads the Brain and Creativity Institute at the University of Southern California and is the author of DESCARTES’ ERROR and the new book THE STRANGE ORDER OF THINGS: Life, Feeling, and the Making of Cultures.
