This book began as a series of intercollegiate lectures given at Bikbeck College, University of London, in 1963, and, although little of the original material remains unchanged, some of the book's general characteristics derive from its origin. The lecture audience consisted for the most part of interested readers rather than specialist; the book is primarily addressed to a similar audience and views and interpretations of interest to the specialist.
