Observation non-obtrusive was also a key tool during the thesis experiment. To begin with, the mechanism of the Galilean telescopes had been explained in terms of geometrical optics and the nature of the objects that they imaged was consistent; for example a distant lake would not resemble a tree when seen through a telescope. Make an outline You already have the dissertation proposal, which is a preliminary outline for the actual dissertation. Thesis experiment expected evidence: When participant honesty might be compromised, it should be listed as a limitation of the study rather than an assumption. The Scenarios In this chapter I introduce a short series of 3 composite scenarios, compiled as an abstraction built upon typical research cases I studied and considered relevant to my thesis.

Talk:Duhem–Quine thesis - Wikipedia
In philosophy of science , confirmation holism , also called epistemological holism , is the view that no individual statement can be confirmed or disconfirmed by an empirical test, but rather that only a set of statements a whole theory can be so. It is attributed to Willard Van Orman Quine who motivated his holism through extending Pierre Duhem 's problem of underdetermination in physical theory to all knowledge claims. Duhem's idea was, roughly, that no theory of any type can be tested in isolation but only when embedded in a background of other hypotheses, e. Quine thought that this background involved not only such hypotheses but also our whole web of belief , which, among other things, includes our mathematical and logical theories and our scientific theories. This last claim is sometimes known as the Duhem—Quine thesis. In his own words, "Any statement can be held true come what may , if we make drastic enough adjustments elsewhere in the system. By astronomers found that the orbit of planet Uranus around the Sun departed from expectations.

The Duhem—Quine thesis , also called the Duhem—Quine problem , after Pierre Duhem and Willard Van Orman Quine , is that it is impossible to test a scientific hypothesis in isolation, because an empirical test of the hypothesis requires one or more background assumptions also called auxiliary assumptions or auxiliary hypotheses. In recent decades the set of associated assumptions supporting a thesis sometimes is called a bundle of hypotheses. The Duhem—Quine thesis argues that no scientific hypothesis is by itself capable of making predictions. For instance, as evidence against the idea that the Earth is in motion, some people objected that birds did not get thrown off into the sky whenever they let go of a tree branch. Later theories of physics and astronomy, such as classical and relativistic mechanics could account for such observations without positing a fixed Earth, and in due course they replaced the static-Earth auxiliary hypotheses and initial conditions.

Dementsprechend kann einerseits eine Theorie nicht durch einzelne empirische Beobachtungen und Experimente verifiziert oder falsifiziert werden — es stehen immer eine Reihe weiterer Theorien mit zur Debatte. Omdat die hypothese onderdeel is van een netwerk van hypotheses web of belief , is het niet duidelijk welke hypothese er precies op de proef wordt gesteld in de zogenaamde cruciale test.
