Willard Van Orman Quine słynne cytaty

„Niebyt musi w pewnym sensie być, gdyż inaczej – czym jest to czego nie ma? Tej powikłanej doktrynie można by nadać miano brody Platona. Historycznie rzecz biorąc, okazała się ona bardzo twarda, stępiając często ostrze brzytwy Ockhama.”

Willard Van Orman Quine

„Być uznanym za przedmiot istniejący to po prostu i zwyczajnie tyle co być wartością pewnej zmiennej. W języku tradycyjnej gramatyki sprowadza się to w przybliżeniu do tego, że „być” znaczy tyle co „być przedmiotem do którego odnosi się pewien zaimek.””

Willard Van Orman Quine

„Efektem uporządkowania języka jest redukcja struktury gramatycznej do logicznej.”

Willard Van Orman Quine

„Ogólnie: teoria zakłada istnienie przedmiotów danego rodzaju wtedy i tylko wtedy, gdy niektóre z tych przedmiotów muszą być wartościami zmiennych po to, by twierdzenia przyjęte w tej teorii były prawdziwe.
Nie chcę tu sugerować zależności bytu od języka. Nie zajmuję się tu ontologicznym stanem rzeczy, lecz ontologicznymi założeniami wypowiedzi. To, co istnieje, nie zależy od niczyjego języka, natomiast to, o czym ktoś mówi, że istnieje, zależy.”

Willard Van Orman Quine

„Wiedza naszych ojców jest materią utkaną ze zdań. W naszych rękach rozwija się ona i zmienia na drodze mniej lub bardziej dowolnych i świadomych rewizji i uzupełnień, na które wpływa mniej lub bardziej pośrednio nieprzerwany ciąg naszych doznań zmysłowych. Jest to tkanina szara, biorąca czerń od faktów i biel od konwencji. Nie znajduję jednak rzeczowych powodów, by mniemać, że są w niej nici całkiem czarne lub też całkiem białe.”

Willard Van Orman Quine

„Logika goni prawdę na drzewie gramatyki.”

Willard Van Orman Quine

„Nie przeczy się więc tu wielkiej roli, jaką we współczesnej matematyce odgrywały systemy nie zinterpretowane. Jest to ogon, który zaczął machać psem.”

“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.”

“Creatures inveterately wrong in their inductions have a pathetic but praiseworthy tendency to die before reproducing their kind.”

Willard van Orman Quine

"Natural Kinds", in Ontological Relativity and Other Essays (1969), p. 126; originally written for a festschrift for Carl Gustav Hempel, this appears in a context explaining why induction tends to work in practice, despite theoretical objections. The hyphen in "praise-worthy" is ambiguous, since it falls on a line break in the source.

“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.”

“My countersuggestion, issuing essentially from Carnap's doctrine of the physical world in the Aufbau, is that our statements about the external world face the tribunal of sense experience not individually but only as a corporate body.”

Les Deux Dogmes de l'empirisme

“The issue over there being classes seems more a question of convenient conceptual scheme; the issue over there being centaurs, or brick houses on Elm Street, seems more a question of fact. But I have been urging that this difference is only one of degree, and that it turns upon our vaguely pragmatic inclination to adjust one strand of the fabric of science rather than another in accommodating some particular recalcitrant experience. Conservatism figures in such choices, and so does the quest for simplicity.”

"Two Dogmas of Empiricism"
From a Logical Point of View: Nine Logico-Philosophical Essays (1953)

“Even a statement very close to the periphery can be held true in the face of recalcitrant experience by pleading hallucination or by amending certain statements of the kind called logical laws. Conversely, by the same token, no statement is immune to revision. Revision even of the logical law of the excluded middle has been proposed as a means of simplifying quantum mechanics; and what difference is there in principle between such a shift and the shift whereby Kepler superseded Ptolemy, or Einstein Newton, or Darwin Aristotle?”

Willard van Orman Quine Two Dogmas of Empiricism

"Two Dogmas of Empiricism"
From a Logical Point of View: Nine Logico-Philosophical Essays (1953)

“Modern empiricism has been conditioned in large part by two dogmas. One is a belief in some fundamental cleavage between truths which are analytic, or grounded in meanings independently of matters of fact, and truths which are synthetic, or grounded in fact. The other dogma is reductionism: the belief that each meaningful statement is equivalent to some logical construct upon terms which refer to immediate experience. Both dogmas, I shall argue, are ill-founded. One effect of abandoning them is, as we shall see, a blurring of the supposed boundary between speculative metaphysics and natural science. Another effect is a shift toward pragmatism.”
