Scientism is the belief that science, especially natural science, is the most valuable part of our culture. Although not confined to philosophers, it is from Bacon and Descartes up to the naturalized epistemology of Quine that the clearest statements of the scientistic attitude are to be found. This book shows how Western philosophy has been dominated by an identification with the aims of science and the rationality of its methods. This has resulted in attempts to either dismiss the unscientific or to put it on a scientific footing. The author criticizes this scientific view of philosophy, wishing not to devalue science but to increase the value placed on the arts and humanities. He insists that philosophy is not a science and condemns recent attempts "in the name of naturalism" to revive the project of a scientific philosophy.
