The Socratic, or dialog, form is central to the history of philosophy and has been the disciplinea s canonical genre ever since. Paul Feyerabenda s Three Dialogues on Knowledge resurrects the form to provide an astonishingly flexible and invigorating analysis of epistemological, ethical and metaphysical problems. He uses literary strategies -- of irony, voice and distance -- to make profoundly philosophical points about the epistemic, existential and political aspects of common sense and scientific knowledge. He writes about ancient and modern relativism; the authority of science; the ignorance of scientists; the nature of being; and true and false enlightenment. Throughout Three Dialogues on Knowledge is provocative, controversial and inspiring. It is, unlike most current philosophical writing, written for readers with a keen sense of what matters and why.
