He contemplated the entirety of human knowledge as being one unit of empirical significance.Hence all our knowledge, for Quine, would be epistemologically no different from ancient Greek gods, which were posited in order to account for experience.

The Duhem–Quine thesis (also called the Duhem–Quine problem) states 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).Quine also notes that deviant logics usually lack the simplicity of classic logic, and are not so fruitful.Following Duhem and Quine, Norwood Russell Hanson (1924 – 1967) developed a concept of "theory ladenness" or "theory loadedness" of observation that observation language and theory language are deeply interwoven.Thomas Kuhn cited the Duhem–Quine thesis as one of the reasons why paradigms are incommensurable.In direct reference to the Duhem–Quine thesis, Larry Laudan argued that: indeterminary does not threaten the scientific rationality; although indeterminacy is logically possible and true, a rational choice is possible by maintaining a high degree of coherence and consistency.This prevents a theory from becoming conclusively falsified through empirical means if the background assumptions are not proven (since background assumptions sometimes involve one or more scientific theories, and scientific theories are never strictly proven).For instance, to "disprove" the idea that the Earth was moving, some people noted that birds did not get thrown off into the sky whenever they let go of a tree branch.Following the Duhem–Quine thesis, Norwood Russell Hanson developed the concept of "theory-ladenness" of observation; observation does not constitute neutral, objective data, but a theory dependent interpreted knowledge.Together with Thomas Kuhn's argument for the existence of the socio-historical dimension in scientific knowledge, the Duhem–Quine thesis made a significant contribution to the philosophy of science and theory of knowledge.Duhem believed that only in the field of physics can a single individual hypothesis not be isolated for testing.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.
