he learned to appreciate the value of empiricism and its language of concrete, complex things, in sharp contrast to the more abstract, clear and simple ideas of the Cartesian method. By 1886, as part of his doctoral dissertation, he had completed the draft of his The Division of Labour in Society, and was working towards establishing the new science of sociology. Academic career Durkheim's period in Germany resulted in the publication of numerous articles on German social science and philosophy; Durkheim was particularly impressed by the work of Wilhelm Wundt. Durkheim's articles gained recognition in France, and he received a teaching appointment in the University of Bordeaux in 1887, where he was to teach the university's first social science course. His official title was , thus he taught both pedagogy and sociology (the latter having never been taught in France before). The appointment of the social scientist to the mostly humanistic faculty was an important sign of changing times and the growing importance and recognition of the social sciences. From this position Durkheim helped reform the French school system, introducing the study of social science in its curriculum. However, his controversial beliefs that religion and morality could be explained in terms purely of social interaction earned him many critics. Also in 1887, Durkheim married Louise Dreyfus. They had two children, Marie and André. The 1890s were a period of remarkable creative output for Durkheim. In 1893, he published The Division of Labour in Society, his doctoral dissertation and fundamental statement of the nature of human society and its development. Durkheim's interest in social phenomena was spurred on by politics. France's defeat in the Franco-Prussian War led to the fall of the regime of Napoleon III, which was then replaced by the Third Republic. This in turn resulted in a backlash against the new secular and republican rule, as many people considered a vigorously nationalistic approach necessary to rejuvenate France's fading power. Durkheim, a Jew and a staunch supporter of the Third Republic with a sympathy towards socialism, was thus in the political minority, a situation that galvanized him politically. The Dreyfus affair of 1894 only strengthened his activist stance. In 1895, he published The Rules of Sociological Method, a manifesto stating what sociology is and how it ought to be done, and founded the first European department of sociology at the University of Bordeaux. In 1898, he founded L'Année Sociologique,
