This paper examines a recurrent problem in Friedrich Schiller's thinking: the unity of reason in the autonomy of the main forms of rationality. It is here analyzed in the context of Schiller's correspondence with the Prince of Augustenburg in 1793 and of the essay "The Moral Utility of Aesthetic Manners". The purpose of the paper is to discuss this problem from the perspective of the connection between the aesthetical sphere and the practical reason. According to Schiller, taste would be a necessary condition of freedom.
