A student of Lévi-Strauss, Descola conducted ethnographic research among the Achuar of the upper Amazon in the late 1970s, focusing on how native societies relate to their environment. In this book he sheds fresh light on the evolution of his thinking from structuralism to an anthropology beyond the human, on the critique of the modern separation between nature and society, and above all on the genesis and scope of his major work . This synthesis of the ways in which humans view their relationships with non-humans proposes four schemas for the ‘composition of worlds’ (animism, naturalism, totemism, analogism) that characterize our ways of inhabiting the earth.
