 Sociology has a double status. It is not just one science among the others, as though there is the science of society just as there is a science of living beings. Rather, sociology is the science that comes after all the others; and as the final science, it must assume the task of coordinating the development of the whole of knowledge. With sociology, positivity takes possession of the last domain that had heretofore escaped it and had been considered forever inaccessible to it. Many people thought that social phenomena are so complex that there can be no science of them. Dilthey’s idea of Geisteswissenschaft, for instance, is explicitly directed against positivism and maintains the difference between natural philosophy and moral philosophy. On the contrary, according to Comte, this distinction, introduced by the Greeks, is abolished by the existence of sociology, and the unity that was lost with the birth of metaphysics restored (1830 (58), v. 2, 713–715).
