His views on the sublime are expressed in two papers, "The Sublime" and "The Pathetic," in which we trace considerable influence of Lessing and Winckelmann. He is led especially to strong antagonism against the French tragedy, and he indulges in a lengthy consideration of the passage of Virgil on Laocoon, showing the necessity of suffering and the pathetic in connection with moral adaptations to interest us deeply. All these essays bespeak the poet who has tried his hand at tragedy, but in his next paper, "On Grace and Dignity," we trace more of the moralist. Those passages where he takes up a medium position between sense and reason, between Goethe and Kant, are specially attractive. The theme of this paper is the conception of grace, or the expression of a beautiful soul and dignity, or that of a lofty mind. The idea of grace has been developed more deeply and truly by Schiller than by Wieland or Winckelmann, but the special value of the paper is its constantly pointing to the ideal of a higher humanity. In it he does full justice to the sensuous and to the moral, and commencing with the beautiful nature of the Greeks, to whom sense was never mere sense, nor reason mere reason, he concludes with an image of perfected humanity in which grace and dignity are united, the former by architectonic beauty (structure), the last supported by power. The following year, 1795, appeared his most important contribution to aesthetics, in his Aesthetical Letters. In these letters he remarks that beauty is the work of free contemplation, and we enter with it into the world of ideas, but without leaving the world of sense. Beauty is to us an object, and yet at the same time a state of our subjectivity, because the feeling of the conditional is under that which we have of it. Beauty is a form because we consider it, and life because we feel it; in a word, it is at once our state and our art. And exactly because it is both it serves us as a triumphant proof that suffering does not exclude activity, nor matter form, nor limitation the infinite, for in the enjoyment of beauty both natures are united, and by this is proved the capacity of the infinite to be developed in the finite, and accordingly the possibility of the sublimest humanity.
