The purpose of this paper is to present some “turns” (the transnational and the spatial) that emerged in the context of criticism of the traditional historiography of science; approaches structured by the idea of circulation which, incidentally, has become a resource of analysis by showing how science has been a process in which scientists from different latitudes have participated in a global process of circulation of scientific knowledge. The scheme I follow is this: in the first moment (sections 2 and 3) of a purely expository nature, I present the two “turns”, maintaining circulation as the common thread. In the second moment (section 4) I interpret them, proposing the circulation of scientific knowledge as the foundation of the supra-individual (if you will, collective) nature of scientific activity, while proposing a (generic) methodological scheme to study circulation in the sciences.
