Based on a close reading of the interview that Michel Foucault gave Hérodote, the geography journal newly established and managed by Yves Lacoste in 1976, this article-through the study of spatial metaphors-unfolds the concepts and functions of space used by the philosopher and by geographers. The article proposes an archaeological approach-inspired by Foucault's thinking-in writing the history of the spatial turn and understanding the role played by geography and geographers in this "reassertion of space in critical social theory."
