The idea for this book emerged from my reading of a biography of Albert Einstein (Folsing, 1997), which noted that the only autobiography written by Einstein was in the form of a chapter in a book edited by Paul Arthur Schilpp (1949) as part of his Library of Living Philosophers (LLP). The plan of the LLP was to approach a leading philosopher and request an “intellectual autobiography,” or authorized biography, of his or her publications. In the resulting book, this autobiographical work would be followed by a series of expository chapters and critical essays written by noted exponents and opponents of the philosopher’s perspective. The LLP autobiographies often illuminated how these ideas grew into significant philosophical movements. Of special interest is how they reflected their originators’ own special and personal experiences.
