The project investigates the conception of space in the young Rudolf Carnap, especially in Der Raum (1922), where he proposes an n-dimensional topological space as an attempt to reconcile Kantian philosophy with non-Euclidean geometries, incorporating phenomenological influences. Ernst Cassirer is also considered as an alternative approach that reformulates space as a historical symbolic form. The research is situated within the crisis of the Kantian notion of space, engaging with Riemann and Reichenbach, and adopts Michael Friedman’s interpretation, according to which relativized constitutive a priori principles sustain scientific rationality and the commensurability between paradigms. Thus, the project aims to examine how the proposals of Carnap and Cassirer offer distinct responses to the reformulation of the a priori in light of early twentieth-century scientific transformations, clarifying their role in the constitution of experience and the structure of scientific rationality.
