Rudolf Carnap vs W. V. O. Quine

Carnap and Quine were the two most important figures of mid-twentieth-century analytic philosophy. Quine studied with Carnap in Prague in the 1930s and the two engaged in extended philosophical correspondence; their dispute over the analytic-synthetic distinction is one of the canonical episodes of analytic philosophy.

Where they agree

Both held that philosophy should be continuous with the natural sciences and that empiricism is the right starting point in epistemology, both took modern logic as the central tool of philosophical analysis, and both rejected metaphysics as it had been traditionally practiced. Carnap shaped Quine's framework decisively, and Quine acknowledged the debt throughout his career.

Where they disagree

Carnap held that statements divide cleanly into the analytic — true by virtue of meaning alone — and the synthetic, true or false by virtue of how the world is. Different philosophical questions could then be treated as internal to a chosen linguistic framework, with no further metaphysical dispute available. Quine, in Two Dogmas of Empiricism, denied the analytic-synthetic distinction: there is no principled way to distinguish meaning-truths from world-truths, and our beliefs face the tribunal of experience as a single web rather than as analytic and synthetic strata. The dispute reframed mid-century empiricism and shaped subsequent analytic philosophy decisively.

  • “To be is to be the value of a variable.”

    On What There Is

  • “Nonbeing must in some sense be, otherwise what is it that there is not? This tangled doctrine might be nicknamed Plato's beard ; historically it has proved tough, frequently dulling the edge of Occam's razor .”

    On What There Is

  • “Wyman's overpopulated universe is in many ways unlovely. It offends the aesthetic sense of us who have a taste for desert landscapes.”

    On What There Is", p. 4. a humorous comment on the idea "unactualized possible".
