Abstract

For a half a century, Claude Lévi-Strauss multiplied statements about the demographic situation of humanity and its anthropological consequences. Those statements, often seen as shocking, were interpreted as a kind of aberration which defied rational understanding. Current opinion held was that the analysis of such idiosyncratic ideas overstepped the competence of anthropologists and historians. In fact, as shown in my text based on newly discovered archival materials, quite the opposite is true. Firstly, Lévi-Strauss became interested in demography very early in his career. Secondly, his conception of demographic trends and their effects was based on scholarly knowledge. Thirdly, far from being an idiosyncratic extravagance, his demography corresponded to widely shared concerns, central to the cultural policies of UNESCO, in which Lévi-Strauss was involved as Secretary general of the International Social Science Council (from 1952 to 1961). These facts are necessary if one is to grasp the cosmological outlook underlying the works of Claude Lévi-Strauss. The principles of Lévi-Straussian cosmology, in which demography plays an important role, are not reducible to the axioms of his structural theory. Without taking this cosmological infrastructure into account we are unable to correctly understand the moral message that Lévi-Strauss endeavoured to deliver, which concerned the extreme dangers humanity could face in the near future.
