A World Of Pure Experience William James
William James a psychologist and philosopher:
Along with Charles Sanders Peirce and John Dewey, James is considered to be one of the major figures associated with the philosophical school known as pragmatism, and is also cited as one of the founders of functional psychology. A Review of General Psychology survey, published in 2002, ranked James as the 14th most cited psychologist of the 20th century. He also developed the philosophical perspective known as radical empiricism. James' work has influenced intellectuals such as Émile Durkheim, W. E. B. Du Bois, Edmund Husserl, Bertrand Russell, Ludwig Wittgenstein, Hilary Putnam, and Richard Rorty, and has even influenced Presidents, such as Jimmy Carter.
Born into a wealthy family, James was the son of the Swedenborgian theologian Henry James Sr. and the brother of both the prominent novelist Henry James, and the diarist Alice James. James wrote widely on many topics, including epistemology, education, metaphysics, psychology, religion, and mysticism. Among his most influential books are The Principles of Psychology, which was a groundbreaking text in the field of psychology, Essays in Radical Empiricism, an important text in philosophy, and The Varieties of Religious Experience, which investigated different forms of religious experience, which also included the then theories on mind-cure
I remember when I study my bachelor degree in psychology that William James was a "must-read" philosopher, since he founded one of the psychology schools, the functional psychology, which later developed as the behaviorist school. The roots of such philosophy schools can be traced back to Greece in the philosophy of Epicurus and Aristotle.
Thanks for the comments. I'm just starting to look at James' stuff as well as some of the Greeks, fascinating!
Also, I suggest you to take a look over the works of Edward Thorndike, a James' disciple, regarding educational psychology and the Law of Effect.
