This chapter of the book turns to the ‘when?’ question of mindreading: when and how often we need to attribute psychological states to others. Although it sounds sensible at the outset, this question turns out to be difficult to pin down. In the light of the previous chapters, it should be clear that there are at least two questions hidden here: when do we attribute propositional attitudes to others, and when do we make do with attributing non-propositional attitudes? And are there instances when both occur?
