Quote

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.

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.

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.

An indirect quotation we can usually expect to rate only as better or worse, more or less faithful, and we cannot even hope for astrict standard of more and less what is involved is evaluation, relative to special purposes, of an essentially dramatic act.

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 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.

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.

It is one of the consolations of philosophy that the benefit of showing how to dispense with a concept does not hinge on dispensing with it.

... 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.

To be is to be the value of a variable.

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

Confusion of sign and object is original sin coeval with the word.

The scientist is indistinguishable from the common man in his sense of evidence, except that the scientist is more careful.

To define an expression is, paradoxically speaking, to explain how to get along without it. To define is to eliminate.

No two of us learn our language alike, nor, in a sense, does any finish learning it while he lives.

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.

A curious thing about the ontological problem is its simplicity. It can be put into three Anglo-Saxon monosyllables: 'What is there?' It can be answered, moreover, in a word--'Everything'--and everyone will accept this answer as true.

We do not learn first what to talk about and then what to say about it.

Language is a social art.

For me the problem of induction is a problem about the world: a problem of how we, as we are now (by our present scientific lights), in a world we never made, should stand better than random, or coin-tossing chances changes of coming out right when we predict by inductions. . . .
