Gillies the duhem thesis and the quine thesis

But at the time, no one could show it was these assumptions, rather than the new theory promulgate, which was false. Confirmation holism Quine, on the other hand, in " Two Dogmas of Empiricism ", presents a much stronger version of underdetermination in science.

The thrust of this contrast is that QT is a much stronger thesis than DT, the scope of the former being impressively vast, the scope of the latter being limited to physical theory.

For a freely falling heavy body, acceleration is constant. University of Pittsburgh Press, 17— The strong version of the thesis along this dimension instead asserts that it is always normatively or rationally defensible to retain any hypothesis in the light of any evidence whatsoever, but this latter, stronger version of the claim, Laudan suggests, is one for which no convincing evidence or argument has ever been offered.

In an influential discussion, Larry Laudan and Jarrett Leplin argue that philosophers of science have invested even the bare possibility that our theories might have empirical equivalents with far too much epistemic significance.

Son Objet et sa Structure Paris: Science and Values Revisited, M. Duhemian challenges and problems of underdetermination are often raised to argue that fNI is of little, if any, epistemic value for psychology. The conclusions of such a theory, if the theory is fully developed, are subject to experimental inquiry, which itself requires translation into the abstract.

If we consider any finite group of data points, an elementary proof reveals that there are an infinite number of distinct mathematical functions describing different curves that will pass through all of them.

We know nothing about that. On the other hand, if the outcome of the test is not that predicted, it is logically possible that the hypothesis under test is sound and the error lies in one or more of the auxiliaries.

All of this represents a significant departure from DQT, which has nothing explicit to say about locating error in a theoretical structure or even about possibility of determination at all, and in this way DT is a stronger thesis than DQT.

He also goes on to argue that at least two genuine cosmological theories have serious, nonskeptical, and nonparasitic empirical equivalents: It is for this very reason that when the interpretation of an experiment finds itself in contradiction with a theoretically established conclusion, it is impossible to tell where in the theoretical construct there is error: University of Minnesota Press, pp.

QT in no way disallows a theory to contain such definitions, but it denies them their analyticity. Stanford argues that a convincing case for contrastive underdetermination of this recurrent, transient variety can indeed be made, and that the evidence for it is available in the historical record of scientific inquiry itself.

The former is useless to physical theory unless it is translated into the language of physical theory, since physical theory is an abstract structure of relations that attempts to represent an ontological order.

Such empirical equivalents invite the natural response that they force our theories to undertake commitments that they never should have in the first place. It seems that the consequences of DT and QT led both Duhem and Quine to a very similar epistemological conclusion, one that can arguably be placed under the broad banner of virtue epistemology.

Thus QT comes out again as a much stronger thesis than DT. As famous as this quot;thesis quot; may be, Duhem,pp. But in condemning this system as a whole by declaring it stained with error, the experiment does not tell us where the error lies. And in all of these respects, Laudan claims, partisans have defended only the weaker forms of underdetermination while founding their further claims about and conceptions of the scientific enterprise on versions much stronger than those they have managed or even attempted to defend.

The Aim and Structure of Physical Theory.

Thus, Quine saw the traditional distinction between analytic and synthetic beliefs as simply registering the endpoints of a psychological continuum ordering our beliefs according to the ease and likelihood with which we are prepared to revise them in order to reconcile the web as a whole with our sense experience.

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.

On both accounts, then, our response to recalcitrant evidence or a failed prediction is constrained in important ways by preexisting features of the existing web of beliefs, but for Quine the continuing force of these constraints is ultimately imposed by the fundamental principles of human psychology such as our preference for minimal mutilation of the web, or the pragmatic virtues of simplicity, fecundity, etc.

Donald Gillies, The Duhem thesis and the Quine thesis -. 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.
