Assertion (SEP)
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.[1]
By an account of assertion is here meant a theory of what a speaker does (e.g., expresses a belief) in making an assertion. According to such accounts, there are deep properties of assertion: specifying those properties is specifying what asserting consists in. There must also be surface properties, which are the properties by which a competent speaker can tell whether an utterance is an assertion, for instance that it is made by means of uttering a sentence in the indicative mood.
We shall classify accounts according to two parameters. Firstly, we distinguish between normative and descriptive accounts. Normative accounts rely on the existence of norms or normative relations that are essential to assertoric practice. Descriptive accounts don’t. Secondly, we distinguish between content-directed and hearer-directed accounts. Content-directed accounts focus on the relation between the speaker and the content of the proposition asserted, while hearer-directed accounts focus on the relations between speaker and hearer. Some theories have both normative and descriptive components.
