Abstract
This paper re-examines a key feature of Emile Durkheim’s sociology of knowledge from a critical realist perspective. It is argued that Durkheim’s attempt to establish a social basis for the categories in The Elementary Forms of Religious Life should be understood along ontological rather than epistemological lines. This brings to light new problems with the argument which, however, can be brought fruitfully into contact with the more recent social psychological literature on collective intentionality. This yields insights into future lines of inquiry into social cognition and theories of human conceptualizing capacities.
