david hartley

English physician and philosopher credited with the first formulation of the psychological system known as associationism. Attempting to explain how thought processes occur, Hartley's associationism, with later modifications, has endured as an integral part of modern psychological theory. Hartley was also noted for advocating a physiological psychology divorced from metaphysics.
