 Note that the notion of accord in play in the case of following a rule is also in play in our conception of mental states with intentional content generally. Say that one intends to attend the performance of Sartre’s play No Exit at the Hopewell Theatre on Wednesday. Then, one’s attending the performance at the Hopewell on Wednesday accords with one’s intention (in the sense that it fulfils it), while one’s staying at home to grade logic exams fails to accord with it. Say that one believes that the cat is on the mat. Then, the state of affairs in which the cat is on the mat accords with one’s belief (in the sense that it renders it true), while the state of affairs in which the cat is on the roof does not. Say that one desires to smoke a Bolivar Number 3. Then, one’s smoking a Bolivar Number 3 accords with one’s desire (in the sense that it satisfies it), while one’s smoking a Café Crème does not accord with it. Given this, arguments about rule-following have consequences for our conception of mental content: if an argument shows that there are no facts about what rule an agent is following, it may also show that there are no facts about the contents of a thinker’s mental states.
