William James (1842–1910) authored some of America's most original and evocative philosophy and psychology. Until recently, however, his work in ethics attracted little interest, despite suggestions from such distinguished peers as John Dewey that ethical themes suffused his writings. Taking those suggestions seriously, Clifford S. Stagoll provides an original and rigorous interpretation of James's ethics as a response to the socio-economic circumstances of his day, derived from key themes in his metaphysics, philosophical psychology, philosophy of religion, and pedagogical theory. By considering these apparently disparate projects together, Stagoll shows how James's recommendations for pursuing a richer, more rewarding life—an ethics in the classical sense—are justified by intricate and sophisticated analyses of how we think, act, and conceive of ourselves. For James, making a habit of experimenting with life's myriad opportunities is not just a way to counter thinking that has grown too rigid, but a crucial precondition for making the most of one's life and self.
