SUMMARY
This paper aims to present the exemplarity of an intellectual meeting between a French intellectual, trained in history and geography at the Sorbonne, France (before spending time in Spain during the beginning of his doctorate), and the “Brazilian terrain”. From his training to his work as a university professor in Brazil, what I want to characterize is a transnational intellectual context in the domain of the history of science, using geographical reasoning as a reference. However, before becoming aware of these intellectual processes, it should be said that at the base of this context lies the Brazilian space. This kind of reasoning as a proposed methodology is named here the geohistory of knowledge. In this paper, I seek to present this methodology and its theoretical and empirical results, focusing on how the construction of contextualization can be related to space.
