The philosophical significance of quine's d-thesis by bradley r munro thesis presented to the faculty of graduate studies of the university of waterloo. Abstract having been struck by the steady growth of mathematical knowledge, duhem wondered whether a similar cumulative pattern had also been achieved in the development of physical science. Pierre maurice marie duhem (french: [pjɛʁ moʁis maʁi dyɛm] was a french physicist, mathematician, historian and philosopher of science he is best known for his work on chemical thermodynamics, for his philosophical writings on the indeterminacy of experimental criteria, and for his historical research into the science of the european middle ages.

But like people use popper's falsification theory selectively to things they disagree with, people use the quine-duhem thesis and similar uncertainty-type things selectively to argue the legitimacy of certain things. The quine-duhem thesis: evidence does not usually ‘prove’ or ‘disprove’ any particular theory or hypothesis in a number of popular accounts of the progress of science, we are told that there was some dispute between advocates of two rival theories. However, in 1906 pierre duhem argued that the falsification of a theory is necessarily ambiguous and therefore that there are no crucial experiments one can never be sure that it is a given theory rather than auxiliary or background hypotheses which experiment has falsified. The quine-duhem thesis as stated above seems to provide a method to deny falsification as proposed by the crucial experiment and by the popperian method the crucial experiment is vulnerable to the quine-duhem attack in part because of the crucial experiment's reliance on modus tollens.
This reversal of the relation between theory and facts, that theory is first and facts second, is the basis of the next philosophy of science that we shall look at, popper’s theory of falsification, and indeed rose out of the insurmountable problems of ‘inductionism. Quine-duhem thesis 4 recovers the symmetry between falsification and verification when we take into account the role of the auxiliary assumptions ( aa ) of the theory ( t ): falsification verification. 41) quine refers to duhem's 1906 french version of the aim and structure of physical theory and proceeds to argue that the unit of empirical significance between the propositions of mathematics and logic which are independent of factduhem's thesis on the problematical nature of falsification has taken on a new lease of life in modern times as.
The significance of quine's indeterminacy thesis author(s): michael dummett source: synthese, vol 27, no duhem held that physical but theory is always underdetermined by the available evidence, in that no that any could show conclusively falsifying experiment or observation it could of a theory was false, although single constituent. A new look at falsification in light of the duhem-quine thesis by andrew lewthwaite as an answer to difficulties associated with the traditional inductive method, karl popper responds with falsification, a deductive scientific method where, as he describes it, [a] scientist, whether theorist or experimenter, puts forward statements, or systems of statements, and tests them step by step.

43 quine-duhem’s thesis of hypothesis in quine’s thesis of hypothesis, quine claims that it is not impossible to experiment a particular hypothesis on isolation because every theory must necessarily come as a part of a given environment of theories. Quine thesis, in boston studies in the philosophy of science (ed wartofsky) 2 cf duhem's aim and structure of physical theory (trans wiener), part ii, chapter vi and passim. A popular criticism of karl popper is that his criterion of falsifiability runs aground on the duhem-quine thesis that is, for any putative falsification, it’s always possible to preserve a scientific hypothesis by revising auxiliary hypotheses in its stead.

Independently of popper's problem with the duhem-quine thesis, that very thesis has come under criticism by bayesians who argue that testing of target hypotheses is possible despite their being embedded in auxiliary hypotheses, thus freeing theories for popperian falsification, but in an un-popperian manner.

Recently, some of the supporters of popperian positivism have attempted to refute the duhem–quine thesis by proposing an interpretation of falsification which can survive the idea that a theory can be rejected if one of its hypotheses clashed with an observation (cross, 1982. The duhem-quine thesis is false, in my opinion, or at least any interesting version of it is false however, it cannot be solved by simple application of occam's razor, if only because there are conflicting versions of occam's razor. Summary: the quine-duhem thesis is a form of the thesis of the underdetermination of theory by empirical evidence the basic problem is that individual theoretical claims are unable to be confirmed or falsified on their own, in isolation from surrounding hypotheses.
