Schiller and Goethe divide the empire over modern German poetry, and represent its two principal powers; the one, Schiller, impassioned and lyrical, pours his soul over all the subjects he touches; in him every composition, ode, or drama is always one of his noble ideas, borrowing its dress and ornament from the external world. He is a poet especially through the heart, by the force with which he rushes in and carries you with him. Goethe is especially an epic; no doubt he paints the passions with admirable truth, but he commands them; like the god of the seas in Virgil, he raises above the angry waves his calm and sublime forehead. After this glance at the position and chief characteristics of Schiller, it may be useful to offer a few remarks on those of the principal works in this volume, his Æsthetical Letters and Essays. Schiller, in his Æsthetical Essays, did not choose the pure abstract method of deduction and conception like Kant, nor the historical like Herder, who strove thus to account for the genesis of our ideas of beauty and art. He struck out a middle path, which presents certain deficiencies to the advocates of either of these two systems. He leans upon Kantian ideas, but without scholastic constraint. Pure speculation, which seeks to set free the form from all contents and matter, was remote from his creative genius, to which the world of matter and sense was no hinderance, but a necessary envelop for his forms. His removal to Jena in 1791, and acquaintance with Reinhold, familiarized him with the Kantian philosophy, but he only appreciated it by halves. The bare and bald dealing with fundamental principles was at this time equally repulsive to Goethe and Schiller, the man of the world and the man of life. But Schiller did not find anywhere at that time justice done to the dignity of art, or honor to the substantial value of beauty. The Æsthetical Essays in this volume appeared for the most part since 1792, in the “Thalia” and the “Hours” periodicals. The first, “On the Ground of our Pleasure in Tragic Subjects” (1792), applies Kantian principles of the sublime to tragedy, and shows Schiller’s lofty estimate of this class of poetry. With Kant he shows that the source of all pleasure is suitableness; the touching and sublime elicit this feeling, implying the existence of unsuitableness. In this article he makes the aim and source of art to consist in giving enjoyment, in pleasing. To nature pleasure is a mediate object, to art its main object. The same proposition appears in Schiller’s paper on Tragic Art (1792), closely connected with the former. This article contains views of the affection of pity that seem to approximate the Aristotelian propositions about tragedy.
