For the first time, Ray Monk goes behind the public face and reveals how the genius and the lover empowered each other. Russell's inner life was torn between the poles of rigorous principle and romantic desire. Monk's superb narrative portrays how this conflict shaped and drove Russell's highest intellectual achievements. This volume concludes with the end of his pursuit of philosophy and the start of a life, at 49, devoted to journalism and fatherhood. Four eight-page photo inserts.
