My topic in this paper is social understanding. By this I mean the cognitive skills underlying social behaviour and social coordination. Normal, encultured, non-autistic and non-brain-damaged human beings are capable of an impressive degree of social coordination. We navigate the social world with a level of skill and dexterity fully comparable to that which we manifest in navigating the physical world. In neither sphere, one might think, would it be a trivial matter to identify the various competences which underly this impressive level of performance. Nonetheless, at least as far as interpersonal interactions are concerned, philosophers show a rare degree of unanimity. What grounds our success in these interactions is supposed to be our common mastery of (more or less similar versions of) folk psychology.

Most philosophers would, I think, be inclined to agree on something like the following minimal characterization of folk psychology.
