In this paper, I discuss several issues about space. Namely, how Kant comes to a comprehension of space that affirms both its ideal and absolute character; how, following Husserl, the space representation relates to the sphere of formal essences that redefines geometry as a theory of abstract manifolds; how the continuity of space interferes in the constitution of the physical thing in the framework of Husserlian phenomenology, and, finally, the results of a supposedly regress to an original dimension of space, as proposed by Heidegger.
