June 25, 1908 - December 25, 2000
Perhaps the most important American philosopher of the twentieth century.

Intellectual Legacy
Quine was a logician by training. His arguments were devastating to some of the most central dogmas of analytic philosophy, shaking up logic, metaphysics, epistemology, philosophy of science, and philosophy of language.

For the most part, he spent his career at Harvard. Early in his academic career, Quine came under the influence of members of the Vienna Circle, especially Rudolf Carnap. Although his work would expose serious flaws in the foundations of Carnap's (logical positivist, empiricist) view, Quine struggled to remain true to the spirit of positivism. He remained empiricist and physicalist, and was a great proponent of naturalism -- the view that philosophy is like a natural science, investigating phenomena in the real world, and should borrow its methods from science.

He was also a great prose stylist, delightful to read. This doesn't mean, however, that his ideas are laid bare in his papers; they go down easy but are very tough to fully digest. Part of the difficulty in understanding him is that he has divided loyalties -- as I said above, he wanted to stay true to elements of Carnap's positivist program, while at the same time, he was doing work that was devastating to that program. He was a huge figure in the transition from logical positivism (and its dismissal of metaphysics) to later 20th century analytic philosophy (and its devoted examination of metaphysics) -- the tensions of the transition are evident in his work, and sometimes make him say confusing or apparently contradictory stuff (IMHO).

His famous/influential doctrines include:

He published 22 books, was awarded honorary degrees from 18 universities, and was the recipient of numerous other honors. He travelled and lectured widely throughout his life and was the mentor and advisor of a great many of today's famous philosophers, including Donald Davidson. (He also taught songwriter Tom Lehrer and Unabomber Theodore Kaczynski.) His political views were notoriously right-wing.

All his books were typed on the 1927 Remington typewriter, on which he wrote his doctoral thesis, which he had modified by including some mathematical symbols instead of characters such as !, ?, and 1. When once he was asked how he managed without a question mark he replied:

Well, you see, I deal in certainties.
