Duhem–Quine thesis

The geometrical optic functioning of the Galilean telescope does not lend itself to the creation of fictitious images. The following illustrations by Galileo accordingly refute one of the two alternative bundles of hypotheses

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.
