could become scientific only when they were stripped of their metaphysical abstractions. Realism A second influence on Durkheim's view of society beyond Comte's positivism was the epistemological outlook called social realism. Although he never explicitly espoused it, Durkheim adopted a realist perspective in order to demonstrate the existence of social realities outside the individual and to show that these realities existed in the form of the objective relations of society. As an epistemology of science, realism can be defined as a perspective that takes as its central point of departure the view that external social realities exist in the outer world and that these realities are independent of the individual's perception of them. This view opposes other predominant philosophical perspectives such as empiricism and positivism. Empiricists, like David Hume, had argued that all realities in the outside world are products of human sense perception, thus all realities are merely perceived: they do not exist independently of our perceptions, and have no causal power in themselves. Comte's positivism went a step further by claiming that scientific laws could be deduced from empirical observations. Going beyond this, Durkheim claimed that sociology would not only discover "apparent" laws, but would be able to discover the inherent nature of society. Judaism Scholars also debate the exact influence of Jewish thought on Durkheim's work. The answer remains uncertain; some scholars have argued that Durkheim's thought is a form of secularized Jewish thought, while others argue that proving the existence of a direct influence of Jewish thought on Durkheim's achievements is difficult or impossible. Durkheim and theory Throughout his career, Durkheim was concerned primarily with three goals. First, to establish sociology as a new academic discipline. Second, to analyse how societies could maintain their integrity and coherence in the modern era, when things such as shared religious and ethnic background could no longer be assumed. To that end he wrote much about the effect of laws, religion, education and similar forces on society and social integration. Lastly, Durkheim was concerned with the practical implications of scientific knowledge. The importance of social integration is expressed throughout Durkheim's work: Establishing sociology Durkheim authored some of the most programmatic statements on what sociology is and how it should be practiced. His concern was to establish sociology as a science. Arguing for a place for sociology among other sciences, he wrote, "sociology is, then, not an auxiliary of any other
