The problems dealt with in The Idea of a Social Science are philosophical. It is an attempt to place the social science, considered as a single group, on the intellectual map, with special attention to the relations of the discipline to philosophy on the one hand and the natural sciences on the other. The author holds that the relation between the social sciences and philosophy is commonly misunderstood because of certain fashionable misconceptions about the nature of philosophy, and because of an incorrect assessment of the significance of some of Wittgenstein's contributions. He discusses the influence of the natural sciences on our conception of the social sciences and examines some of the most influential ideas of J.S. Mill, Pareto and Max Weber.
