With his customary incisiveness, W. V. Quine presents logic as the product of two factors, truth and grammar—but argues against the doctrine that the logical truths are true because of grammar or language. Rather, in presenting a general theory of grammar and discussing the boundaries and possible extensions of logic, Quine argues that logic is not a mere matter of words.
Quine has few if any equals as an expositor of logic… The field in which he has made himself preeminent is that of the philosophy of logic, to which…Philosophy of Logic is a short but brilliant introduction.
By virtue of intellectual power, range and fertility of ideas and brilliance of presentation, Quine is the most distinguished and influential of living philosophers.
Quine pursues his philosophical vision with an uncompromising consistency of purpose that makes his doctrines impossible to ignore. You either go with him or define your position in reaction to his. And this is one mark of a great philosopher.
