W. V. O. Quine 1908 – 2000

Willard Van Orman Quine was a 20th-century American philosopher and logician, one of the most influential analytic philosophers of the post-war era. His landmark 1951 essay Two Dogmas of Empiricism rejected the analytic-synthetic distinction and the doctrine of reductionism, both central to logical positivism, and argued for a holistic conception of knowledge in which our beliefs face experience only as a corporate body. His Word and Object developed the indeterminacy of translation thesis and a behaviourist account of meaning. His ontological motto, that to be is to be the value of a variable, framed decades of subsequent debate over what exists. He spent his entire career at Harvard University, where he held the Edgar Pierce Chair of Philosophy.

Willard Van Orman Quine (1908–2000) was one of the most influential analytic philosophers of the twentieth century and the figure through whom American empiricism was reshaped after World War II. Born in Akron, Ohio, he studied at Oberlin and Harvard, where he received his PhD under Whitehead in 1932, traveled to Vienna and Prague where he studied with Carnap, and held the Edgar Pierce Chair in Philosophy at Harvard from 1956 until his retirement.

Quine's most influential single paper, Two Dogmas of Empiricism (1951), denied the analytic-synthetic distinction that had structured Carnap's logical empiricism. Quine argued that there is no principled way to distinguish meaning-truths from world-truths, and that our beliefs face the tribunal of experience as a single web rather than as analytic and synthetic strata. The paper reframed mid-century empiricism and shaped the subsequent analytic tradition decisively.

Quine's other major contributions include Word and Object (1960), which developed the doctrine of the indeterminacy of translation; the regimentation of natural-language ontology through first-order logic with identity; the slogan no entity without identity; and the naturalization of epistemology, which holds that the proper inheritor of traditional epistemology is empirical psychology. He died in Boston in 2000 at ninety-two, having shaped almost every subsequent debate in analytic philosophy of language, mind, and ontology.
