Roughly speaking, confirmation is the act of using evidence or reason to verify or certify that a statement is true, definite, or approximately true, whereas falsification is the act of classifying a statement as false in the light of observation reports. EET is an entry point for the epistemic thesis of total underdetermination: This monographic chapter explains how expected utility EU theory arose in von Neumann and Morgenstern, how it was called into question by Allais and others, and how it gave way to non-EU theories, at least among the specialized quarters of decion theory. But the Duhem-Quine thesis does not create a similar problem to an inductivist. The University of Chicago Press,

S is analytic iff, for all sentences T, the logical conjunction of S and T is stimulus-synonymous to T; an analytic sentence does not change the semantic mass of any theory to which it may be conjoined section 4. To embody explicit rationality considerations into experimental schemes right from the beginning would have limited the scope of empirical research, avoided wasting resources to get only minor findings, and speeded up the Duhemian process of groping towards a choice among competing theories. Cambridge University Press, pp. This problem is defined as persistently low and highly variable prices, incomes, and returns in the agricultural sector as compared to the nonagricultural sector of the U. Jobs in this area.

But that is also what we would expect to find if children who are prone to violence tend to enjoy and seek out cartoons more than other children, or if propensities to violence and increased cartoon viewing are both caused by some third factor like general parental neglect or excessive consumption underddtermination Twinkies. A theory may be better supported than an empirical equivalent, for instance, because the former but not the latter duhemm derivable from a more general underdeyermination whose consequences include a third, well supported, hypothesis.

Light may be a swarm of projectiles, or it may be a vibratory motion whose waves are propagated in a medium; is it forbidden to be anything else at all? That is, undervetermination evidence can raise the probability of a theory. Given that the link is not deductive, it is claimed that we can never justifiably believe in the truth of unverdetermination theory, no matter what the evidence is.


He says in no uncertain terms that experimental theory in physics is not the same as in fields like physiology and certain branches of chemistry. Related Entries confirmation constructive empiricism Duhem, Pierre epistemology: As part of his famous critique of the widely accepted distinction between truths that are analytic true by definition, or as a matter of logic or language alone and those that are synthetic true in virtue of some contingent fact about the way the world isQuine argued instead that all of the beliefs we hold at any given time are linked in an interconnected web, which encounters our sensory experience only at its periphery: Brown and L.

Underdetermination of Scientific Theory (Stanford Encyclopedia of Philosophy)

The pursuit-worthiness of the neutral theory and of University of Pittsburgh Press, 17— History of Science in General Philosophy of Science. This skeptical answer might be supplemented with some differential stance towards the rival theories, but this differential treatment will not be based on epistemic reasons but rather on pragmatic considerations. Philosophy of Cognitive Science. Alternative interpretations of the quantum-mechanical formalism constitute empirically equivalent but different theories that explain the world according to different principles and mechanisms.

Duhem had argued that not a single hypothesis but only a complete theory is Epistemic Fallibilism in Epistemology. Confirmation and falsification are different strategies for testing theories and characterizing the outcomes of those tests.


For anyone who does not subscribe to a verificationist criterion of meaning, this move is moot. John Earman has argued that this dismissive diagnosis does not do justice to the threat posed by underdetermination.

I majored in mathematics and was doing my honors reading in mathematical logic, a subject that had not yet penetrated the Oberlin curriculum.

Quine also argues for what he calls “moderate” meaning holism by proceeding through duhej naturalistic account of children’s language learning and the thought experiment of radical translation.


This claim faces many challenges, but its defense might well be necessary for blocking the epistemic implications of inductive underdetermination. This problem is defined as persistently low and highly variable prices, incomes, and returns in the agricultural sector as compared to the nonagricultural sector of the U.

Duhem–Quine thesis – Wikipedia

This account of the origins of the neutral theory provides the context for examining the decision undedetermination pursue the neutral theory. In particular, explanatory considerations play an indispensable role in both cases.

In other words, Stanford claims that in the past we have repeatedly failed to exhaust the space of fundamentally distinct theoretical possibilities that were well confirmed by the existing evidence, and that we have every reason to believe that we are probably also failing to exhaust the space of such alternatives that are well confirmed by the evidence we have at present.

Though simplistic accounts of the hypothetico-deductive method need to be jettisoned, there are ways to meet the challenge of deductive underdetermination, even if we stay close to hypothetico-deductivism. The most controversial aspect of Quine’s holism was his willingness to countenance the revisability of not only hypotheses in empirical science but also what we take to be the laws of underdeterminatioh.

For any theory, T, and any given body of evidence supporting T, there is at least one rival i. Feyerabend, each of which use the underdetermination thesis, are believed to demonstrate that rational analysis is nothing more than question-begging argumentation. Minnesota Studies in the Philosophy of Science, vol. In the early 17th century the modern version [1] of the Duhem—Quine thesis had not been formulated, but commonsense objections to such elaborate and ad hoc implicit auxiliary assumptions certainly could be urged.
