This paper explores three important interrelated themes in Putnam’s philosophy: language, meaning, and the context-sensitivity of “truth-evaluable content.” It shows how Putnam’s own version of semantic externalism is able to steer a middle course between an internalism about meaning that requires a “language of thought” (or “mentalese”) and a mind-independent realism about meaning that requires Platonic objects (or other such “abstract entities”), while doing justice to how ascriptions of meaning are causally related to the objective world. The following account is (...) able to allow for the primacy of language over thought while ensuring that the content of thought is partially fixed by the external world. The emphasis in Putnam’s later writings on the “context sensitivity” of meaning are often construed as marking a major departure from his earlier thought. It is here argued that such an interpretation involves a misunderstanding both of the commitments of Putnam’s original form of semantic externalism and of the implications of the version of context sensitivity he embraces.
