Epistemological rupture
Epistemological rupture (or epistemological break) is a notion introduced in 1938 by French philosopher Gaston Bachelard, and later used by Louis Althusser. Bachelard proposed that the history of science is replete with "epistemological obstacles"—or unthought/unconscious structures that were immanent within the realm of the sciences, such as principles of division (e.g., mind/body).
