This paper responds to an argument against a kind of anthropology. According to the argument, if the aim of anthropology is to describe the different worldviews of different groups, then anthropologists should only refer to material artefacts in order to illustrate a worldview; but the interest of artefacts to anthropology goes beyond mere illustration. This argument has been endorsed by key members of the ontological movement in anthropology, who found at least one of its premises in Marilyn Strathern’s writing.
