Phenomenotechnique: Bachelard's critical inheritance of conventionalism

Abstract

The concept of phenomenotechnique has been regarded as Bachelard's most original contribution to the philosophy of science. Innovative as this neologism may seem, it benefited from a generation of debates on the nature and status of scientific facts, among conventionalist thinkers and their opponents. Granting that Bachelard stood among the opponents to conventionalism, this article nonetheless reveals deep similarities between his work and that of two conventionalist thinkers who insisted on what we call today the theory-ladenness of scientific experiment: Pierre Duhem and Édouard Le Roy. This article, therefore, compares Bachelard's notion of phenomenotechnique with Duhem's developments on the double character of scientific instruments, and with Le Roy's claim that scientific facts are fabricated to meet the requirements of theory. It shows how Bachelard retained Duhem and Le Roy's views on the interplay between theory and experiment but rejected their sceptical conclusions on the limitations of experimental control. It claims that this critical inheritance of conventionalism was made possible by a reflection on technology, which led Bachelard to re-evaluate the artificiality of scientific facts: instead of regarding this artificiality as a limitation of science, as Le Roy did, he presented it as a condition for objective knowledge.
