This article aims to help to break the academic impasse which still stifles the possibilities for an informed debate between feminist psychologists, anthropologists, archaeologists and biologists on one side and evolutionary psychologists, anthropologists, archaeologists, neuroscientists and biologists on the other. Arguing that mainstream feinist theory inherited a theory of knowledge in which the body is divided into an under-theorized biological body/brain and a free-floating cultural grid that structures collective respresentations, the author seeks to show why Cartesian dualism remains unsolved, in spite of its contested ontological status in feminist research.
