Oedipus, for example, consists of the overrating of blood relations and the underrating of blood relations, the autochthonous origin of humans and the denial of their autochthonous origin. Influenced by Hegel, Lévi-Strauss believed that the human mind thinks fundamentally in these binary oppositions and their unification (the thesis, antithesis, synthesis triad), and that these are what makes meaning possible. Furthermore, he considered the job of myth to be a sleight of hand, an association of an irreconcilable binary opposition with a reconcilable binary opposition, creating the illusion, or belief, that the former had been resolved. Lévi-Strauss's theory is set forth in "Structural Anthropology" (1958). Briefly, he considers culture a system of symbolic communication, to be investigated with methods that others have used more narrowly in the discussion of novels, political speeches, sports, and movies. His reasoning makes best sense when contrasted against the background of an earlier generation's social theory. He wrote about this relationship for decades. A preference for "functionalist" explanations dominated the social sciences from the turn of the 20th century through the 1950s, which is to say that anthropologists and sociologists tried to state the purpose of a social act or institution. The existence of a thing was explained, if it fulfilled a function. The only strong alternative to that kind of analysis was historical explanation, accounting for the existence of a social fact by stating how it came to be. The idea of social function developed in two different ways, however. The English anthropologist Alfred Reginald Radcliffe-Brown, who had read and admired the work of the French sociologist Émile Durkheim, argued that the goal of anthropological research was to find the collective function, such as what a religious creed or a set of rules about marriage did for the social order as a whole. Behind this approach was an old idea, the view that civilization developed through a series of phases from the primitive to the modern, everywhere in the same manner. All of the activities in a given kind of society would partake of the same character; some sort of internal logic would cause one level of culture to evolve into the next. On this view, a society can easily be thought of as an organism, the parts functioning together as do the parts of a body. In contrast, the more influential functionalism of Bronisław Malinowski described the satisfaction of individual needs, what a person derived by participating in a custom.
