It has been claimed that the integration of history and philosophy of science is nothing but a marriage of convenience. I think this is wrong — it is really a passionate romance, and I argue why in a recent co-written paper. Beyond a discussion of what is to be gained by integrated HPS in principle, we focus particularly on the methodology of integration in practice: how should we relate philosophical concepts to historical cases, and vice versa? Our penultimate draft is now on the PhilSci Archive.
The paper is forthcoming in a collected volume titled The Philosophy of Historical Case Studies, which was co-edited by Tilman Sauer and myself and will appear in the Boston Studies in the Philosophy and History of Science.
