What distinguishes full-on stating a proposition from merely communicating it? For instance, what distinguishes claiming/asserting/saying that one has never smoked crack cocaine from merely implying/conveying/hinting this? The enormous literature on ‘assertion’ provides many approaches to distinguishing stating from, say, asking and commanding: only the former aims at truth; only the former expresses one’s belief; etc. But this leaves my question unanswered, since in merely communicating a proposition one also aims at truth, expresses a belief, etc.

My aim is not to criticize extant accounts of the state-vs.-merely-convey contrast, but rather to draw on clues from Dummett, functional linguistics and moral theory, to offer a novel one. The main idea is that full-on stating is distinctively conventionalized in a way that conversationally implicating, hinting, giving to understand, etc., are not. Specifically, full-on stating is constitutively tied to a particular conventional, linguistic, function-bearing device, the declarative sentence. To full-on state that p is to hit that ‘target speech act’ which owes its existence to that special-purpose device. It is therefore also to make one’s action lie-prone. Nonetheless, once that sui generis target is there to be aimed for, a person may reach it without using the special-purpose tool – e.g., one may full-on state using a mere word or phrase, or coded hand signals, or semaphore.

I end by considering several philosophical implications of this means of capturing the contrast.
