For this reason, the moral potential of art must be governed by a firm recognition of the fundamental principles of morality itself (ibid., p. 78). Sulzer does not make the mistake of thinking that the experience of fine art, valuable as it can be for sound morality and politics, can substitute for a direct grasp of sound principles of morality and politics. Although his emphasis on the moral potential of the heightened sensitivity (Empfindlichkeit) that can be developed through aesthetic education may have been an important source for Schiller, he would not have gone as far as the latter does in his Letters on Aesthetic Education in suggesting that aesthetic education is both a necessary and sufficient condition for moral regeneration.
