  Quine treats knowledge as embodied in language. Apart from other considerations, language-use is observable and thus subject to scientific inquiry. Quine’s concern with how we might acquire knowledge thus takes the form of a concern with how we might acquire cognitive language. But his interest here is in epistemology, rather than in language for its own sake: “I am interested in the flow of evidence from the triggering of the senses to the pronouncements of science…. It is these epistemological concerns, and not my incidental interest in linguistics, that motivate my speculations.” (1990b, 3).
