July 19, 1970. Running time: 26:36. In this address given at the Colonial Church of Edina in Minneapolis, Minnesota, Thurman explores the sense in which human beings belong to the world of nature and are genetically close to some animals. The one difference is that humans are self-conscious, and it is this self-consciousness of our minds that causes us to regard ourselves as having power over nature, time, space, and the lives of other human beings.
