To follow him critically in all the by-ways of his theorizing would require a treatise; and the treatise would be dull reading, except, peradventure, to such as might be specially interested in the history of aesthetic discussion. In the end, too, it would shed but little light upon Schiller's later plays, which were in no sense the offspring of theory and were influenced only in a very general way by their author's previous philosophical studies. To understand the poet's development it is nowise necessary to lose one's self with him in the Serbonian bog of metaphysic. On the other hand, it _will_ be useful to know what the problems were that chiefly interested him, and to see how he attacked them and what conclusions he arrived at. With the soundness of his reasoning and the final value of his contributions to the literature of aesthetics we need hardly concern ourselves at all; since the scientific questions involved are differently stated and differently approached at the present time.[94]
The pre-Kantian stage of Schiller's aesthetic philosophy is of quite minor importance. He obtained his original stock of ideas at the Stuttgart academy from Ferguson's 'Institutes', as translated by Garve. In Ferguson, who rested strongly upon Shaftesbury, no line was drawn between the moral and the aesthetic domain. It was taught that all truth is beauty and that 'the most natural beauty in the world is honesty and moral truth'. Perfection was made to depend on harmony and proportion; and moral beauty upon the harmony of the individual soul with the general system of things. Wrong action was regarded as discord, imperfection. Virtue, being a disposition toward the general harmony, necessarily meant happiness. Thoughts of this kind, mixed up with vague ideas of a pre-established harmony, constituted the staple of Schiller's early philosophizing. The identity of the good, the true and the beautiful, was for him the highest of all generalizations, though more a matter of pious emotion than of close thinking.
Nor do we observe any noteworthy change of attitude in the minor philosophic writings, such as the letters of Julius and Raphael, and the second book of 'The Ghostseer',--which he published prior to his acquaintance with Kant. In these it is always the moralist that speaks, and the great question is the bearing of skepticism on individual happiness. But by the end of his first year in Weimar the moralist had begun to retreat before the aesthetic philosopher. For the author of 'The Gods of Greece' and 'The Artists', it is evident that the beautiful has become the corner-stone of the temple. He saw before him all at once a new region that invited exploration. If art had played such a commanding role in the history of the world, it was evidently of the greatest importance to understand it. It was this feeling for the dignity of art, as the greatest of factors in human perfectibility, that led him to devote the leisure afforded by his Danish pension to a thorough study of Kantian aesthetics.
