More quotes by Willard Van Orman Quine

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.

We do not learn first what to talk about and then what to say about it.
Willard Van Orman Quine
Image
The familiar material objects may not be all that is real, but they are admirable examples.

Image
Science is not a substitute for common sense, but an extension of it.
Willard Van Orman Quine

We cannot stem linguistic change, but we can drag our feet. If each of us were to defy Alexander Pope and be the last to lay the old aside, it might not be a better world, but it would be a lovelier language.

Implication is thus the very texture of our web of belief, and logic is the theory that traces it.

Yields falsehood when preceded by its quotation.

I have been accused of denying consciousness but I am not conscious of having done so.

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.

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.

Language is a social art.

It is within science itself, and not in some prior philosophy, that reality is to be identified and described.
Willard Van Orman Quine

Unlike Descartes, we own and use our beliefs of the moment, even in the midst of philosophizing, until by what is vaguely called scientific method we change them here and there for the better. Within our own total evolving doctrine, we can judge truth as earnestly and absolutely as can be, subject to correction, but that goes without saying.

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.

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.

One man's antinomy is another man's falsidical paradox, give or take a couple of thousand years.

Treating 'water' as a name of a single scattered object is not intended to enable us to dispense with general terms and plurality of reference. Scatter is in fact an inconsequential detail.

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

The word 'definition' has come to have a dangerously reassuring sound, owing no doubt to its frequent occurrence in logical and mathematical writings.

Theory may be deliberate, as in a chapter on chemistry, or it may be second nature, as in the immemorial doctrine of ordinary enduring middle-sized physical objects.
