Eric Schwitzgebel is a professor of philosophy at University of California, Riverside, and a co-operating member of UCR’s program in Speculative Fiction and Cultures of Science. His fiction has appeared in F&SF, Clarkesworld, Nature, The Dark, Unlikely Story, and elsewhere. He has published two books of philosophy with MIT Press, as well as dozens of academic journal articles in both philosophy and psychology. In recent academic work he has argued, among other things, that the external world probably exists. (Whew.) He has not yet accumulated an infinite number of books, but to his wife’s dismay he has made substantial progress in that direction.
