Claude Lévi-Strauss was a French anthropologist and ethnologist, "father of modern anthropology". He argued that the "savage" mind had the same structures as the "civilized" mind and that human characteristics are the same everywhere. His book Tristes Tropiques, positioned him as a central figures in the structuralist school of thought. Structuralism has been defined as "the search for the underlying patterns of thought in all forms of human activity."
Claude Lévi-Strauss, La pensée sauvage (1962), a classic of structuralist anthropology. The cover image is of wild pansies, which makes a nice pun in French with the alternate meaning of "savage thought." Edmund Leach, in his little book on Lévi-Strauss, made a connection also with Shakespeare's Hamlet, where Ophelia observes, "And there is pansies; that's for thoughts."
