 Different components and phases of Feyerabend’s work have influenced very different groups of thinkers. His early scientific realism, contextual theory of meaning, and the way he proposed to defend materialism were taken up by Paul and Patricia Churchland. Richard Rorty, for a time, also endorsed eliminative materialism. Feyerabend’s critique of reductionism has influenced philosophers of science such as Cliff Hooker, Bas van Fraassen, and John Dupré, and his general point of view influenced books such as Alan Chalmers’ well-known introduction to philosophy of science What Is This Thing Called Science? (1978).
