Meaning Holism

Meaning holism is the thesis that the meaning of an expression is determined by its place in the entire network of beliefs and inferences within a language or conceptual system — no term has meaning in isolation, and any change in belief anywhere in the network potentially affects the meaning of every term. The position is most associated with W.V.O. Quine's attack on the analytic-synthetic distinction and with Donald Davidson's truth-conditional semantics, both of which reject the idea that meanings are discrete mental entities assignable to words one by one.

Holism explains why translation is indeterminate — why no amount of behavioral evidence uniquely determines what a foreign speaker means — and why scientific theory change involves meaning change as well as belief change. But it faces the charge of making communication impossible: if your entire network differs from mine, how do we ever mean the same thing by the same word? The answer — that meaning is stabilized by shared practice and partial overlap rather than identity — connects holism to the pragmatic turn and to the social construction of linguistic norms. The debate between holists and molecularists — those who hold that meaning is determined by a smaller subset of associated beliefs — drives much of contemporary philosophy of language.
