Intellectual rebel, romantic pragmatist, aristocratic pluralist, William James was both a towering figure of the nineteenth century and a harbinger of the twentieth. Drawing on a wide range of sources, including 1,500 letters between James and his wife, acclaimed biographer Linda Simon creates an intimate portrait of this multifaceted and contradictory man. Exploring James's irrepressible family, his diverse friends, and the cultural and political forces to which he so energetically responded, Simon weaves the many threads of William James's life into a genuine, and vibrant, reality.
