Abstract In this essay, which was his presidential address to the Philosophy of Science Association, Ernan McMullin argued that the watershed between “classic” philosophy of science (by this meaning, not just logical positivism but the logicist tradition in theory of science stretching back through Kant and Descartes to Aristotle) and the “new” philosophy of science can best be understood by analyzing the change in our perception of the role played by values in science. He begins with some general remarks about the nature of value, goes on to explore some of the historical sources for the claim that judgement in science is value-laden, and concludes by reflecting on the implications of this claim for traditional views of the objectivity of scientific knowledge-claims.
