philosopher named John Dewey. He came up with his own theory of emotion by grafting Darwin’s essentialist views from Expression onto James’s anti-essentialist ideas, even though they are fundamentally incompatible. The result was a Frankenstein’s monster of a theory that inverted James’s meaning by assigning an essence to each emotion category. For the finishing touch, Dewey named his concoction after James, calling it “the James-Lange theory of emotion.”* Today, Dewey’s role in this jumble is forgotten, and countless publications attribute his theory to James.
