 Whether this argument succeeds depends on whether it can be shown that the role of meaning in motivating action is equivalent to that of prescriptions. Thus, the fact that “green” means green may of course guide the speaker’s actions in the sense that any facts do so—i.e., if \(S\) believes that “green” means green. To show that meaning facts play a normatively guiding role, therefore, it does not suffice to appeal to the idea that meaning facts play a role in motivating action; it also has to be shown that the motivating role is that of a prescription rather than a belief (see  section 2.2  below).[26]
