The work of Gaston Bachelard is known for two crucial concepts, that of the epistemological rupture and that of phenomenotechnique. A crucial question is, however, how these two concepts relate to one another. Are they in fact essentially connected or must they be seen as two separate elements of Bachelard’s thinking? This paper aims to analyse the relation between these two Bachelardian moments and the significance of the concept of phenomenotechnique for today. This will be done by examining how the (...) concepts of Bachelard have been used from the 1960s on. From this historical perspective, one gets the impression that these two concepts are relatively independent from each other. The Althusserian school has exclusively focused on the concept of ‘epistemological break’, while scholars from Science & Technology Studies, such as Bruno Latour, seem to have only taken up the concept of phenomenotechnique. It in fact leads to two different models of how to think about science, namely the model of purification and the model of proliferation. The former starts from the idea that sciences are rational to the extent that they are purified and free from obstacles. Scientific objectivity, within this later model, is not achieved by eradicating all intermediaries, obstacles and distortions, but rather exactly by introducing as many relevant technical mediators as possible. Finally, such a strong distinction will be criticized and the argument will be made that both in Bachelard’s and Latour's thought both concepts are combined. This leads to a janus-headed view on science, where both the element of purification and the element of proliferation are combined. (shrink)

This article is a reflection on chance as a scientific object, starting from a materialistic point of view. I analyze the relationship between motion and complexity by introducing the notion of an open system and the categories that result from it: state of nature and observable, to review the debate on chance and certainty.

The scientific work of Leonardo da Vinci may have served as the main inspiration for the historical research of George Sarton. Although he never produced a work he felt was worthy of its subject, the little that he did write about Leonardo reveals the importance he attributed to him in the history of science. This is especially clear in Sarton´s treatment of Leonardo and a discovery he did not make: William Harvey´s discovery of blood circulation in the 17th Century. In (...) this article, we refer to this particular episode to trace Sarton´s conception of the development of science. It is a conception that illustrates well the traditional historiographic perspective that is the target of Thomas Kuhn´s criticisms. Although Kuhn never wrote about Leonardo or Harvey, we aim to show that he clearly positioned himself contrary to Sarton, albeit indirectly, with respect to this particular historical episode, as well.
