A tradition from the ancestors

The study of the history of science is widely understood to be undergoing a profound and much-needed transformation, from a subject focused on Europe to one encompassing the entire world. Yet the aims of the field have always been global. During the decades after the Second World War the inevitable progress of Western science was seen as the key to its role in world history. From the 1970s the rise of cultural history and laboratory ethnographies undermined this assumption. Indebted to colonial anthropology, these approaches revealed that the power of science was not inherent, but the result of local and contingent processes. Explanation needed to be symmetrical in analysing practices of all kinds wherever they were found, from economics and divination in West Africa to supernatural healing and particle physics in the American heartland. The geographical and conceptual broadening of the field is thus a long-delayed outcome of developments extending back many decades. It also means that references to the 'global' in history of science - even more than elsewhere in the humanities - continue to resonate with the universalizing aims of the natural and social sciences.
