Part of the material contained in the present book was presented in the form of a lecture course given by me at the University of Oxford in I962 as a Fulbright Senior Lecturer. Scripps College and the Claremont Graduate School contributed to the cost of research and publication. The staff of the Honnold Library, Claremont, California, was extremely obliging in matters concerning inter-library loans. The page proofs were read in part by Professor Richard Walzer, the University of Oxford. Mr. Salih Alich, Blaisdell Institute, Claremont, California, corrected many errors occurring in the transliteration from Arabic in Section V. To all these institutions and persons I express my most sincere thanks. The manuscript was essentially completed early in I960. Scripps College, Claremont, California.
