Peter Caws was born in 1931 in Southall, Middlesex, now part of west London, in a house that can still be seen from the train between Heathrow and Paddington. He was brought up in a repressive fundamentalist sect, the Exclusive Brethren. After a B.Sc. (hons.) in physics from the University of London he escaped to the United States in 1953, where a one-year fellowship at Yale grew into a Ph.D. in philosophy in 1956. There followed teaching stints at Michigan State University and the University of Kansas, and then a brief interlude as an officer of a major foundation, Carnegie Corporation of New York. Back in the academic world he taught at the City University of New York (Hunter College and the Graduate School), and in 1982 became University Professor of Philosophy, and eventually also Professor of Human Sciences, at The George Washington University in Washington, DC. He is now University Professor of Philosophy Emeritus, in residence with the University Honors Program. He has been married twice and has three children, Hilary Caws-Elwitt, Matthew Rorison Caws, and Elisabeth Breslin Caws. His wife, Nancy Breslin, M.D., M.F.A., is a psychiatrist turned fine art photographer.
