Asserting is the act of claiming that something is the case—for instance, that oranges are citruses, or that there is a traffic congestion on Brooklyn Bridge (at some time). We make assertions to share information, coordinate our actions, defend arguments, and communicate our beliefs and desires. Because of its central role in communication, assertion has been investigated in several disciplines. Linguists, philosophers of language, and logicians rely heavily on the notion of assertion in theorizing about meaning, truth and inference. -/- (...) The nature of assertion and its relation to other speech acts and linguistic phenomena (implicatures, presuppositions, etc.) have been subject to much controversy. This entry will situate assertion within speech act theory and pragmatics more generally, and then go on to present the current main accounts of assertion. (shrink)

This paper develops a “Cliffordian” argument for a common epistemic norm governing belief, action, and assertion. The idea is that beliefs are the sorts of things that lead to actions and assertions. What each of us believes influences what we act on and assert, and in turn influences what those around us believe, act on, and assert. Belief, action, and assertion should be held to a common epistemic norm because, otherwise, this system will become contaminated. The paper finishes by drawing (...) out the relativistic implications of the Cliffordian argument. (shrink)
