Abstract

In this article, we provide a detailed discussion of Hasok Chang’s analysis of the Chemical Revolution. Our focus lies on his use of the framework of systems of practice and his claim that the abandonment of the phlogiston theory was irrational. We argue that his framework runs into problems when applied to the chemical revolution because of its static view on the aims of the historical actors and we suggest using Nicholas Jardine’s concept of the reality of questions instead as a more flexible historiographical tool. We show how Chang’s claim regarding the irrational aspects of the chemical revolution follows from his strictly individualistic epistemology, leading him to see institutional and social aspects that impact the determination of aims as external to scientific rationality. We argue that a viable pragmatist and pluralist philosophy of science needs to embrace ‘academic politics’ as an explicit part of its view of rationality.
