W. V. O. Quine

Analytic · North America · 1908 to 2000

American logician who denied a sharp line between truths of meaning and truths of fact. He said knowledge should be seen as part of science.

What it is

Willard Van Orman Quine (1908 to 2000) was one of the most influential American logicians and philosophers of the twentieth century, and he spent nearly his whole academic career at Harvard. He worked in logic and theoretical philosophy, and his contributions to ethics and political philosophy are slight.

He is best known for his arguments against logical empiricism, in particular against its use of the distinction between analytic truths (true by meaning) and synthetic truths (true by how the world is). These arguments belong to a wider view in which philosophy is not a separate discipline above science but one part of the same inquiry.

The main ideas

  • Against the analytic-synthetic divide. In Two Dogmas of Empiricism he argued that there is no sharp, defensible line between truths of meaning and truths of fact.
  • Holism. Our beliefs face experience together, as a connected whole, not one by one, so no single belief is tested in isolation.
  • Naturalism. Philosophy and empirical science are continuous. There is no first philosophy standing above science to judge it.
  • Indeterminacy of translation. There can be more than one correct way to translate a language, with no further fact to decide between them.
  • Ontological commitment. What a theory commits us to is shown by what it says must exist for its statements to be true.

What it looks like in practice

Picture a scientist whose experiment gives an unexpected result, and who has to decide whether to give up a law of physics, doubt the instrument, or change a basic assumption of logic. Quine's point is that nothing marks one of these choices as automatically off limits, so that revising a belief is always a question of weighing the whole web. This is an illustration of the idea, not a quotation.

Books and moments

  • Two Dogmas of Empiricism is the essay that attacks the analytic-synthetic distinction.
  • Word and Object is his book on language, meaning and the indeterminacy of translation.

Questions and criticism

  • Is there really no analytic truth? Defenders of the distinction answer that his argument shows it is hard to draw, not that it is empty.
  • Is naturalism circular? If philosophy is part of science, it is asked what grounds the standards of science itself.
  • Does indeterminacy undermine meaning? If translation has no single right answer, it is debated whether meaning is real at all.

Close neighbours

He argued with Carnap and the logical empiricists. The pages on Russell, Frege and Wittgenstein show the logic and language tradition around him.

Influenced

  • David Lewis · He studied under Quine and began from his clear, exact way of arguing.
  • Donald Davidson · He was Quine's student and carried on his work on meaning and translation.
  • Richard Rorty · Rorty used Quine's rejection of a sharp line between meaning and fact.

Influenced by

  • Bertrand Russell · Quine took Russell's theory of descriptions and his logic as a foundation.
  • David Hume · Quine treats Hume's puzzle about evidence as the starting point of his own view that the study of knowledge is part of science.
  • Gottlob Frege · Quine's logic and his talk of what a theory commits us to grew from Frege. (scholars disagree about this link)
  • Rudolf Carnap · Quine was his friend and student in the 1930s and began from his formal methods.

Reacted against

  • Rudolf Carnap · Quine attacked the sharp line between truths of meaning and truths of fact on which Carnap relied.
