LOOP QUANTUM GRAVITY IN THE LIGHT OF NEO-KANTIAN PHILOSOPHY

The paper surveys the possibility of keeping a neo-Kantian approach in the face of Loop Quantum Gravity (LQG). Together with a preliminary analysis of Cassirer’s reinterpretation of Kantian philosophy that allowed him to harmonize the a priori cognitions with the theory of relativity and quantum mechanics (QM), it will focus on the distinction between constitutive and regulative a priori. In this way, the paper will suggest that despite Rovelli’s refutation of Kant’s interpretation of space and time, he seems, at least implicitly, to hold to a couple of neo-Kantian assumptions: (i) the usage of constitutive a priori principles such as granularity, indeterminism and partially relation, (ii) and the claim for functionalism as a rule in ordering the ‘appearances’.
