Quine, Willard Van Orman

"Meaning is constituted through use in a shared language."

"The empirical content of any statement depends on systematic connections."

"Language is not transparent to reality but opaque."

"We revise our beliefs to maintain overall coherence."

"Thought is constrained by the possibilities of expression."

"Observation is always interpreted through conceptual schemes."

"The analytic-synthetic boundary is a pragmatic convenience, nothing more."

"We project our cognitive structures onto a neutral reality."

"Truth emerges from the fit between belief and experience."

"Identity is multiply realizable and framework-dependent."

"Meaning supervenes on use and intersubjective practice."

"Rationality requires adjusting all beliefs together, never one at a time."

"Language contains the assumptions that structure our thought."

"We know the world only through our interpretive schemes."

"Clarity in thought requires precision in language."

"The web of belief is resilient but ultimately revisable."

"Synonymy is an illusion created by pragmatic equivalence."
