La Philosophie du Non
Bachelard's 1940 articulation of scientific progress as negation — the argument that each genuine advance in knowledge says 'no' to the framework that preceded it.
La philosophie du non (1940) is Bachelard's compact theoretical statement of how scientific progress actually works. Against the view that science advances by addition — new facts accumulating within a stable framework — Bachelard argues that scientific progress is fundamentally negative. Each genuine advance says 'no' to the framework that organized the previous state of knowledge. Oxygen chemistry says no to phlogiston. Relativity says no to absolute space. Quantum mechanics says no to deterministic causation. Non-Euclidean geometry says no to Euclidean axioms. In each case, the 'no' is productive: the negation opens conceptual territory that the previous framework had foreclosed. But the 'no' is also destructive: it makes the previous framework uninhabitable, and the philosopher must be honest about what each 'no' destroys as well as what it opens.
