tradition, meaning that he thought of his study of society as dispassionate and scientific. He was deeply interested in the problem of what held complex modern societies together. Religion, he argued, was an expression of social cohesion. In the field work that led to his famous Elementary Forms of Religious Life, Durkheim, a secular Frenchman, looked at anthropological data of Indigenous Australians. His underlying interest was to understand the basic forms of religious life for all societies. In Elementary Forms, Durkheim argues that the totems the Aborigines venerate are actually expressions of their own conceptions of society itself. This is true not only for the Aborigines, he argues, but for all societies. Religion, for Durkheim, is not "imaginary", although he does deprive it of what many believers find essential. Religion is very real; it is an expression of society itself, and indeed, there is no society that does not have religion. We perceive as individuals a force greater than ourselves, which is our social life, and give that perception a supernatural face. We then express ourselves religiously in groups, which for Durkheim makes the symbolic power greater. Religion is an expression of our collective consciousness, which is the fusion of all of our individual consciousnesses, which then creates a reality of its own. It follows, then, that less complex societies, such as the Australian Aborigines, have less complex religious systems, involving totems associated with particular clans. The more complex a particular society, the more complex the religious system is. As societies come in contact with other societies, there is a tendency for religious systems to emphasize universalism to a greater and greater extent. However, as the division of labour makes the individual seem more important (a subject that Durkheim treats extensively in his famous The Division of Labour in Society), religious systems increasingly focus on individual salvation and conscience. Durkheim's definition of religion, from Elementary Forms, is as follows: "A religion is a unified system of beliefs and practices relative to sacred things, that is to say, things set apart and forbidden – beliefs and practices which unite into one single moral community called a Church, all those who adhere to them." This is a functional definition of religion, meaning that it explains what religion does in social life: essentially, it unites societies. Durkheim defined religion as a clear distinction between the sacred and the profane, in effect this can
