 We have here an analogy with my meaning something by a linguistic expression. Say that I mean blue by ‘blue’. Then, ‘blue’ is correctly applicable to, for example, a US postbox but not to a ripe (Roma) tomato. We can express this point by saying that the former application accords with the predicate’s meaning while the latter application fails to do so. Given this analogy, arguments about rule-following have consequences for our conception of linguistic meaning: if an argument shows that there are no facts about which rule an agent is following, it may also show that there are no facts about what a speaker means by a linguistic expression.
