Much of the rest of his case is taken up with discussing historical examples illustrating that earlier scientists did not simply ignore or dismiss, but instead genuinely failed to conceive of the serious, fundamentally distinct theoretical possibilities that would ultimately come to displace the theories they defended, only to be displaced in turn by others that were similarly unconceived at the time. Our argument is basedon a combination of Quine’s holism with VanFraassen’s constructive empiricism, especiallythe latter’s analysis of empirical adequacy andhis pragmatic approach to explanation. Theresulting reorientation of economic methodologyrestores the capacity of economics to learnfrom experience and reinstates the imperativeof developing alternatives to orthodoxtheorizing in economics. Feyerabend, each of which use the underdetermination thesis, are believed to demonstrate that rational analysis is nothing more than question-begging argumentation. Thus, input extensionalism, and not behaviorism, is what forces the indeterminacy. Explanatory theories become rapidly degenerating if exploratory theories or other auxiliary hypotheses which inform the original confirmation base are modified to accommodate recalcitrant observations. Quine recognized, of course, that many of the logically possible ways of revising our beliefs in response to recalcitrant experiences that remain open to us strike us as ad hoc, perfectly ridiculous, or worse.
They denied the truth of his most startling reports, such as that there were mountains on the moon and satellites around Jupiter. This practice is typically justified by appeal to methodological arguments that purport to demonstrate that active-controlled trials ACTs are methodologically flawed. 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 logic. Pragmatism debate in the philosophies of thesocial sciences. But contrastive underdetermination Section 3 below involves the quite different possibility that for any body of evidence confirming a theory, there might well be other theories that are also well confirmed by that very same body of evidence.
He contemplated the entirety of human knowledge as being one unit of empirical significance. By the end, all that remained of falsificationism was the cautionary tale of a promising but ultimately flawed attempt to solve the problem of demarcation.
The Duhem-Quine Thesis Reconsidered – Part One
Modern empiricism has been conditioned in large part by two dogmas. Translation in Philosophy of Language. In violation of this principle, placebo-controlled trials PCTs continue to be used extensively in the development and licensure of second-generation treatments.
A theory may be better supported than an empirical quind, for instance, because the former but not the latter is derivable from a more general theory whose consequences include a third, well supported, hypothesis.
But the total field is so underdetermined by its boundary conditions, experience, that there is much latitude of choice as to what statements to reevaluate in falsificaionism light of any single contrary experience.
His constructive empiricism holds that the aim of science is not to find true theories, but only theories that are empirically adequate: In particular, we consider i repeated measurements of a single test consequence of the hypothesis, ii measurements of multiple test consequences of the hypothesis, iii theoretical support for the reliability of the instrument, and iv calibration procedures. This solution opens the way Moreover, claims of underdetermination of either of these two fundamental varieties can vary in strength and character in any number of further ways: From my historical study, things did not evolve in this way, and the theory was both proposed and rebutted on the basis of normative arguments already in the s.
Is it in the fundamental hypothesis that light consists in projectiles thrown out with great speed by luminous bodies?
As for epistemological holism, I claim that this thesis does not follow The observation of neutrinos traveling faster than the speed of light never happened; the apparent falsification was predicated upon all the cables being screwed tight.
In The Scientific Imagevan Fraassen uses a now-classic example to illustrate the possibility that even our best scientific theories might have empirical equivalents: Phenomenology in Continental Philosophy. So it seems that Duhem was right to suggest not only that hypotheses must be tested as a group or a collection, but also that it is by no means a foregone conclusion which member of such a collection should be abandoned or revised in response to a failed empirical test or false implication.
Quine, on the other hand, in ” Two Dogmas of Empiricism “, presents a much stronger version of underdetermination in science. It might be said that … it is still impossible … that any theoretical system should ever be conclusively falsified.
But is it really a solution at all? But his straightforward appeal to further epistemic resources like ampliative principles of belief revision that are supposed to help narrow the merely logical possibilities down to those which are reasonable or rationally defensible is itself problematic, at least as part of any attempt to respond to Quine. He supposedly claimed that a single recalcitrant observation was enough, in practice, to definitively falsify any scientific hypothesis.

A popular criticism of Karl Popper duheem that his criterion of falsifiability runs aground on the Duhem-Quine thesis. It either reduces to absurdity by implying that the physical cuhem does nothing to constrain scientific belief, or thwsis weakened by underdetermination to at least the same degree as are rational accounts of scientific belief.
