Significance and influence

In psychology, James's work is of course dated, but it is dated as is Galileo's in physics or Charles Darwin's in biology because it is the originative matrix of the great variety of new developments that are the current vogue. In philosophy, his positive work is still prophetic. The world he argued for was soon reflected in the new physics, as diversely interpreted, with its resonances from Charles Peirce, particularly by Albert Einstein, Bertrand Russell, and the Danish quantum physicist Niels Bohr—a world of events connected with one another by kinds of next-to-next relations, a world various, manifold, changeful, originating in chance, perpetuated by habits (that the scientist calls laws), and transformed by breaks, spontaneities, and freedoms. In human nature, James believed, these visible traits of the world are equally manifest. The real specific event is the individual, whose intervention in history gives it in each case a new and unexpected turn. But in history, as in nature, the continuous flux of change and chance transforms every being, invalidates every law, and alters every ideal.

James lived his philosophy. It entered into the texture and rhythms of his rich and vivid literary style. It determined his attitude toward scientifically unaccepted therapies, such as Christian Science or mind cure, and repugnant ideals, such as militarism. It made him an anti-imperialist, a defender of the small, the variant, the unprecedented, the weak, wherever and whenever they appeared. His philosophy is too viable and subtle, too hedged, experiential, and tentative to have become the dogma of a school. It has functioned rather to implant the germs of new thought in others than to serve as a standard old system for others to repeat.
