Brother of novelist Henry James, William James held views embodied in the tendency to subordinate logical proof to intuitive conviction. He was a vigorous antagonist of the idealistic school of Kant and Hegel, and an empiricist who made empiricism more radical by treating pure experience as the very substance of the world. Taking writings from The Principles of Psychology, Essays in Radical Empiricism and The Meaning of Truth amongst other publications, this edition offers a comprehensive selection of James's writings.
