Durkheim was not the first thinker to attempt to make sociology a science. Auguste Comte, who wished to extend the scientific method to the social sciences, and Herbert Spencer, who developed an evolutionary utilitarian approach that he applied to different areas in the social sciences, made notable attempts and their work had a formative influence on Durkheim. In particular, Durkheim appropriated elements of Comte’s positivism as well as elements of his scientific approach to studying societies. Durkheim’s analysis of the ways in which different parts of society operate to create a functioning whole, as well as his use of the organic analogy, was in many ways inspired by Spencer’s own brand of functionalist analysis. However, Durkheim was critical of these attempts at sociology and felt that neither had sufficiently divorced their analyses from metaphysical assumptions. These were to be found particularly in what Durkheim considered Comte and Spencer’s unilinear models of social development, which were based on a priori laws of social evolution. While Durkheim incorporated elements of evolutionary theory into his own, he did so in a critical way, and was not interested in developing a grand theory of society as much as developing a perspective and a method that could be applied in diverse ways. The sociological method that Durkheim devised, thus, sought to be free of the metaphysical positivism of Comte and Spencer and differed greatly from Comte’s mere extension of the scientific method of the natural sciences to society.
