Rupture Épistémologique
Bachelard's name for the violent disruption through which scientific frameworks shatter — not gradual accumulation but conceptual destruction that makes the previous universe uninhabitable.
The rupture épistémologique — epistemological break — is the cornerstone of Bachelard's philosophy of science. Against the prevailing positivism that treated scientific progress as sedimentary accumulation, Bachelard argued that knowledge advances through discontinuities so complete that the pre-rupture framework becomes not merely wrong but conceptually foreign. Lavoisier did not refine phlogiston theory; he destroyed the categories within which it could be stated. Einstein did not improve Newton; he constructed a different universe. The break is always violent, always disorienting, always irreversible — and applied to the AI moment, it names precisely what happened when machines learned to speak human language: the old framework of sequential friction did not become slower, it became uninhabitable.

Bachelard developed the concept across three major works — The New Scientific Spirit (1934), The Formation of the Scientific Mind (1938), and La philosophie du non (1940) — each elaborating the claim that science progresses through negation rather than affirmation. Every major advance says 'no' to the framework
