In this paper, the author analyses Lefebvre’s book The Production of Space, which gives an interesting perspective on the tradition of the philosophical treatment of the concept of space. Within this framework, two renowned philosophers of German Idealism, Kant and Hegel, occupy a distinguished place. Lefebvre does offer enough material needed for an articulation of modern history of philosophy regarding an epochal change from the problem of temporality towards the problem of space. The author intends to show in what manner is the role and place of those two philosophers distinguished, regarding their understanding of the notion of space and its relation to subjectivity. This relation is not exclusively an epistemological problem, but more importantly, it is tied to the thematising the agency in the sense of social practice and political character of knowledge within social reality.
