This article reframes our understanding of French structural anthropology by considering the work of André Leroi-Gourhan alongside that of Claude Lévi-Strauss. These two anthropologists worked at opposite poles of the discipline, Lévi-Strauss studying cultural objects, like myths and kinship relations; Leroi-Gourhan looking at material artifacts, such as stone tools, bones, arrowheads, and cave paintings. In spite of their difference in focus, these thinkers shared a similar approach to the interpretation of their sources: Each individual object was meaningful only as part (...) of a larger whole. For Lévi-Strauss, structuralism was designed to unlock features of the human mind; for Leroi-Gourhan, to uncover the material processes that underlay human life. Again, in spite of their difference in orientation, both structuralisms produced similar theories of human society. Whether ‘primitive’ or ‘advanced’, all societies functioned the same way: Their institutions worked harmoniously, beyond the intentions of any individual actors, to preserve the stability of the group. This eliminated the basis for thinking one society was superior to another. Finally, the article argues that both Lévi-Strauss and Leroi-Gourhan believed that structural anthropology could found a ‘new humanism’, and thereby rescue modernity from moral degeneration. This ‘new humanism’ could not only produce a universal description of human nature, but also help rethink French colonialism, broker new geopolitical alliances, and prevent the erasure of world cultures. Structural anthropology thus imagined a tight relationship between its social-scientific work and its political-moral mission. (shrink)
