This book is intended as an introduction to Bertrand Russell and his views in a variety of fields. From a long list of possibilities, nine areas have been selected for discussion. Pride of place goes to his work on the foundations of mathematics and to the philosophical method which he developed as a consequence of his successes in that field. There are also examples of the more popular side of his work, with discussions of positions he defended in the philosophy of religion, political philosophy, history and education, and one of the dominant themes of his life -- his political activism.
