The Logic of Relevance The French sociologist Dan
Sperber and the British linguist Deirdre Wilson have shown that
"relevance" constrains the coherence of a discourse and enables its
understanding. Relevance is a relation
between a proposition and a set of contextual assumptions: a proposition is
relevant in a context if and only if it has at least one contextual implication
in that context. The contextual
implications of a proposition in a context are all the propositions that can be
deduced from the union of the proposition with the context. A universal goal in
communication is that the hearer is out to acquire relevant information. Another universal goal is that the speaker
tries to make his utterance as relevant as possible. Understanding an utterance
then consists in finding an interpretation that is consistent with the
principle of relevance. The principle of relevance holds that any act of
ostensive communication also includes a guarantee of its own optimal relevance.
This principle is proven to subsume Grice's maxims. Relevance can arise in three
ways: an interaction with assumptions that yields new assumptions; the
contradiction of an assumption which removes it; additional evidence for an
assumption that strengthens the confidence in it. Implicatures are either
contextual assumptions or contextual implications that the hearer must grasp to
recognize the speaker as observing the principle of relevance. The process of
comprehending an utterance is thus reduced to a process of hypothesis formation
and confirmation: the best hypothesis about the speaker's intentions and
expectations is the one that best satisfies the principle of relevance. Language can make sense only
if speaker and listener cooperate. The US philosopher Donald Davidson points out that language
transmits information. The speaker and the listener share a fundamental
principle to make such transmission as efficient as possible. Such "principle of charity"
(originally introduced by the US philosopher Neil Wilson) asserts that the interpretation to be chosen is the one in which the
speaker is saying the highest number of true statements. During the conversation the listener tries
to build an interpretation in which each sentence of the speaker is coupled
with a truth-equivalent sentence. Language, far from being a
mechanical process of constructing sentences and absorbing sentences, is a
subtle process of cooperating with the other to achieve the goal of
communicating. Back to the beginning of the chapter "Pragmatics" | Back to the index of all chapters |
