Abstract
This paper defends a social functionalist interpretation, modeled on psychological functionalism, of the meanings of social facts. Social functionalism provides a better explanation of the possibility of interpreting other cultures than approaches that identify the meanings of social facts with either mental states or behavior. I support this claim through a functionalist reinterpretation of sociological accounts of the categories that identify them with their collective representations. Taking the category of causality as my example, I show that if we define it instead in terms of its functional relations to moral rules, it becomes easier to recognize in other cultures
