  The gist of these examples is not the requirement that words be uttered in every speech act—we have already observed that speech acts can be performed silently. Rather, their gist is that speech acts involve intentional undertaking of a publicly accessible commitment; further, that commitment is not undertaken simply by virtue of my intending to undertake it, even when it is common knowledge that this is what I am trying to do. Can we, however, give a more illuminating characterization of the relevant intentions than merely saying that, for instance, to assert P one must intentionally put forth P as an assertion? Strawson (1964) proposes that we can do so with aid of the notion of speaker meaning—to which we now turn.
