Summary |
Topics in the philosophy of
language tend to fall into two main branches, pragmatics and semantics. Roughly, semantics deals with
conventional meaning. Theories in formal
semantics for natural language attempt to pair meanings with sentence-context
pairs in some systematic way. A
primary test of correctness for a semantic theory is whether it allows us to
define the logical properties of sentences (such as whether one sentence
logically implies another). The
term “pragmatics” covers both a part of formal semantics, so defined, and also
the study of the ways in which utterances effect communication. The first kind of pragmatic theory
deals with the way in which the extensions of terms and the truth values of
sentences depend on features of the situation in which the sentence is
spoken. The second kind of
pragmatic theory studies the nature of speech acts, such as asserting or asking,
and also the ways in which speakers manage to convey more than the conventional
meaning of the sentence uttered.
It is not always clear where in this taxonomy a given phenomenon should
fall. The topic of presupposition,
for instance, has been located under all of these headings. |
