 In The Philosophy of the Present—a compilation based on the Carus Lectures delivered in late 1930 in Berkeley—Mead outlines his thoughts on nature and time. Mead did not have the opportunity to develop his ideas into a book. (He passed away early in 1931.) In spite of the fact that these lectures were hurriedly written due to obligations that he had as chair of the University of Chicago’s philosophy department, they contain ideas that illuminate his earlier work and indicate the direction of his thought. On the first page of the lectures we are told that “reality exists in a present” and that we do not live in a Parmenidean cosmos (PP, 1). “For a Parmenidean reality does not exist. Existence involves non-existence: it does take place. The world is a world of events” (PP, 1). Our world is one in which change is real and not merely a subjective, perceptual, phenomenon.
