Abstract
Jacques Joseph introduced the epistemological part of the philosophy of Gaston Bachelard. It was based on the interpretation of translated Bachelard's writings (but also some others, especially the Shaping of the Scientific Spirit), and on the basis of them he tried to highlight the key motifs of Bachelard's epistemology and how they are interconnected.
This is primarily about Bachelard's concept of the new scientific spirit and open, non-Cartesian rationalism, as well as the relationship of these ideas to his discontinuous conception of the evolution of science and the fundamental concept of epistemological impediment. Questions related to applied (and regionalized) rationalism are also followed by more technical, but no less important topics for Bachelard, such as accuracy or purity, and the overall importance of experiment as a place of dialectical meeting of theory and substance.
The lecture was followed by a discussion.
