Abstract
The history, philosophy, sociology and even the science of science are by now thriving activities. This is in no way surprising; indeed if one examines the development of each of these approaches to the study of sciences, the surprising thing is that it emerged so comparatively recently. The history of science as an academic discipline tends to begin with a reference to Comte's grand scheme of the mid-nineteenth century, passing through Sarton's great pioneering work of the first half of the present century, largely embodied in the volumes of Isis (1913- ), founded, edited and in no small part written by Sarton himself. At present, so far as one can see, many historians of science are rethinking the great and fairly continuously progressive features of Sarton's account, and the emphasis is turning more and more to the discontinuities.
