FeyerabendThis book is the first comprehensive critical study of the work of Paul Feyerabend, one of the foremost twentieth century philosophers of science. The book traces the evolution of Feyerabend's thought, beginning with his early attempt to graft insights from Wittgenstein's conception of meaning onto Popper's falsificationist philosophy. The key elements of Feyerabend's model of the acquisition of knowledge are identified and critically evaluated.
