More quotes by Willard Van Orman 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

Implication is thus the very texture of our web of belief, and logic is the theory that traces it.
Willard Van Orman Quine
Image
The scientist is indistinguishable from the common man in his sense of evidence, except that the scientist is more careful.

Different persons growing up in the same language are like different bushes trimmed and trained to take the shape of identical elephants. The anatomical details of twigs and branches will fulfill the elephantine form differently from bush to bush, but the overall outward results are alike.

Physics investigates the essential nature of the world, and biology describes a local bump. Psychology, human psychology, describes a bump on the bump.

How are we to adjudicate among rival ontologies? Certainly the answer is not provided by the semantical formula To be is to be the value of a variable this formula serves rather, conversely, in testing the conformity of a given remark or doctrine to a prior ontological standard.

If there is a case for mental events and mental states, it must be that the positing of them, like the positing of molecules, hassome indirect systematic efficacy in the development of theory.
Willard Van Orman Quine

The variables of quantification, 'something,' 'nothing,' 'everything,' range over our whole ontology, whatever it may be and we are convicted of a particular ontological presupposition if, and only if, the alleged presuppositum has to be reckoned among the entities over which our variables range in order to render one of our affirmations true.

Students of the heavens are separable into astronomers and astrologers as readily as the minor domestic ruminants into sheep and goats, but the separation of philosophers into sages and cranks seems to be more sensitive to frames of reference.

The three main medieval points of view regarding universals are designated by historians as realism, conceptualism, and nominalism. Essentially these same three doctrines reappear in twentieth-century surveys of the philosophy of mathematics under the new names logicism, intuitionism, and formalism.

Linguistically, and hence conceptually, the things in sharpest focus are the things that are public enough to be talked of publicly, common and conspicuous enough to be talked of often, and near enough to sense to be quickly identified and learned by name it is to these that words apply first and foremost.

Unscientific man is beset by a deplorable desire to have been right. The scientist is distinguished by a desire to be right.

The familiar material objects may not be all that is real, but they are admirable examples.

Some may find comfort in reflecting that the distinction between an eliminative and an explicative physicalism is unreal.
Willard Van Orman Quine
Image
It is within science itself, and not in some prior philosophy, that reality is to be identified and described.

The lore of our fathers is a fabric of sentences. A pale gray lore, black with fact and white with convention.

We can applaud the state lottery as a public subsidy of intelligence, for it yields public income that is calculated to lighten the tax burden of us prudent abstainers at the expense of the benighted masses of wishful thinkers.

... two men could be just alike in all their dispositions to verbal behavior under all possible sensory stimulations, and yet themeanings or ideas expressed in their identically triggered and identically sounding utterances could diverge radically, for the two men, in a wide range of cases.

Our acceptance of an ontology is, I think, similar in principle to our acceptance of a scientific theory, say a system of physicswe adopt, at least insofar as we are reasonable, the simplest conceptual scheme into which the disordered fragments of raw experience can be fitted and arranged.

Logic is an old subject, and since 1879 it has been a great one.
