Described by the philosopher A.J. Ayer as a work of 'great originality and power', this book revolutionized contemporary thinking on science and knowledge. Ideas such as the now legendary doctrine of 'falsificationism' electrified the scientific community, influencing even working scientists, as well as post-war philosophy. This astonishing work ranks alongside The Open Society and Its Enemies as one of Popper's most enduring books and contains insights and arguments that demand to be read to this day.

We examine Duhem's critique of Maxwell, especially Duhem's complaints that Maxwell's theory is too bold or not systematic enough, that it is too dependent on models, and that its concepts are not continuous with those of the past. We argue that these complaints are connected by Duhem's historical criterion for the evaluation of physical theories. We briefly compare Duhem's criterion of historical continuity with similar criteria developed by "historicists" like Kuhn and Lakatos. We argue that Duhem's rejection of theoretical pluralism (...) was a primary factor preventing him from recognizing Maxwell's work as an autonomous tradition. (shrink)

Contrary to what might be expected given a religious or other motivation, Pierre Duhem's interest in mediaeval science was the result of his surprise encounter with Jordanus de Nemore while working on Les origines de la statique in the late autumn of 1903. Historical assumptions common among physicists at that time may explain this surprise, which occasioned a frantic search for more mediaeval precursors for Renaissance mechanics. It also raised serious historiographical problems that threatened even his methodological views, until they (...) were resolved in his To save the phenomena of 1908. (shrink)
