Willard Van Orman Quine

Willard Van Orman Quine (June 25, 1908 – December 25, 2000) (known to intimates as "Van") was an American philosopher and logician in the analytic tradition. From 1930 until his death 70 years later, Quine was continually affiliated with Harvard University in one way or another, first as a student, then as a professor of philosophy and a teacher of logic and set theory, and finally as a professor emeritus who published or revised several books in retirement. He filled the Edgar Pierce Chair of Philosophy at Harvard from 1956 to 1978. A recent poll conducted among analytic philosophers named Quine as the fifth most important philosopher of the past two centuries. He won the first Schock Prize in Logic and Philosophy in 1993, for "his systematical and penetrating discussions of how learning of language and communication are based on socially available evidence and of the consequences of this for theories on knowledge and linguistic meaning."

Quine falls squarely into the analytic philosophy tradition while also being the main proponent of the view that philosophy is not merely conceptual analysis. His major writings include "Two Dogmas of Empiricism" (1951), which attacked the distinction between analytic and synthetic propositions and advocated a form of semantic holism, and Word and Object (1960), which further developed these positions and introduced Quine's famous indeterminacy of translation thesis, advocating a behaviorist theory of meaning. He also developed an influential naturalized epistemology that tried to provide "an improved scientific explanation of how we have developed elaborate scientific theories on the basis of meager sensory input." He is also important in philosophy of science for his "systematic attempt to understand science from within the resources of science itself" and for his conception of philosophy as continuous with science. This led to his famous quip that "philosophy of science is philosophy enough." In philosophy of mathematics, he and his Harvard colleague Hilary Putnam developed the "Quine-Putnam indispensability thesis," an argument for the reality of mathematical entities.

Famous quotes containing the words van orman quine, willard van orman, orman quine, willard van, van, orman and/or quine:

    To call a posit a posit is not to patronize it. A posit can be unavoidable except at the cost of other no less artificial expedients. Everything to which we concede existence is a posit from the standpoint of a description of the theory-building process, and simultaneously real from the standpoint of the theory that is being built.
    —Willard Van Orman Quine (b. 1908)

    One man’s observation is another man’s closed book or flight of fancy.
    Willard Van Orman Quine (b. 1908)

    We do not learn first what to talk about and then what to say about it.
    —Willard Van Orman Quine (b. 1908)

    The lore of our fathers is a fabric of sentences. In our hands it develops and changes, through more or less arbitrary and deliberate revisions and additions of our own, more or less directly occasioned by the continuing stimulation of our sense organs. It is a pale gray lore, black with fact and white with convention. But I have found no substantial reasons for concluding that there are any quite black threads in it, or any white ones.
    Willard Van Orman Quine (b. 1908)

    Mrs. Van Hopper: Most girls would give their eyes for a chance to see Monte.
    Maxim de Winter: Wouldn’t that rather defeat the purpose?
    Robert E. Sherwood (1896–1955)

    Everything to which we concede existence is a posit from the standpoint of a description of the theory-building process, and simultaneously real from the standpoint of the theory that is being built. Nor let us look down on the standpoint of the theory as make-believe; for we can never do better than occupy the standpoint of some theory or other, the best we can muster at the time.
    —Willard Van Orman Quine (b. 1908)

    The mastery of one’s phonemes may be compared to the violinist’s mastery of fingering. The violin string lends itself to a continuous gradation of tones, but the musician learns the discrete intervals at which to stop the string in order to play the conventional notes. We sound our phonemes like poor violinists, approximating each time to a fancied norm, and we receive our neighbor’s renderings indulgently, mentally rectifying the more glaring inaccuracies.
    —W.V. Quine (b. 1908)
