“Che cosa mi è lecito sperare?” Spunti per un’interpretazione della speranza in Kant

[“What may I hope?”. Starting points for an interpretation of hope in Kant’s thought]. In the Critique of Pure Reason Kant summarizes all the interests of reason in three famous questions: “1. What can I know? 2. What ought I to do? 3. What may I hope?”. The latter question opens the possibility for the reason to overcome its limits in the speculative use and postulates the unity between the kingdoms of freedom and nature. This article explores the function of hope in the sphere of morality and, in particular, in the transition from the subjective to the intersubjective level, focusing on the cooperation for achieving the purpose of the “moral republic” and of the “cosmopolitan world republic”.
