The important thing to notice in this argument is that aesthetic judgments are made to depend upon concepts of the mind. The reason, with its abstractions of 'fitness' and what not, is regarded as the prior and the dominating factor. In the second of the two essays, however, we find a distinct recognition of the fact that emotional excitement may give pleasure in and of itself. Illustrations are brought in,—such as the passion for gaming and for dangerous adventure, and the general love of ghost stories and tales of crime,—which go to show that Schiller by no means overlooked the non-rational element in the pleasure afforded by tragedy. Nevertheless he seems to have attached very little importance to that element, for he goes on to observe that we know only two sources of pleasure, namely, the satisfaction of our bent for happiness (Glückseligkeitstrieb), and the fulfillment of moral laws. As the pleasure we take in acted or narrated suffering cannot proceed from the former, it must spring from the latter and do its work by gratifying the 'bent for activity' (Thätigkeitstrieb), which is a moral bent.—After a long tussle with such hazy abstractions the essayist attempts a working definition and practical discussion of tragedy. This part of the essay is still eminently readable, but need not be analyzed here. Sufficient to say that Schiller regards the excitation of 'sympathy' as the sole aim of tragedy. He has nothing to say of the Aristotelian 'fear' or 'katharsis'; in fact he did not make the acquaintance of Aristotle until 1797.[95]

It would be next in order to consider the lectures of 1792-93, but unluckily they are known only from the notes of a student.[96] As published in 1806 they bear the impress of Schiller's mind, but are too brief and summary to be counted among his works. They show that by 1793 he had come to feel at home in the field of aesthetic speculation. He had read Kant and Moritz and Burke, and was ready with his criticisms. In particular, he had found what he regarded as a weak point in the system of Kant, who had not only made no attempt to establish an objective criterion of beauty, but had summarily dismissed the whole problem as obviously hopeless. Schiller felt that, if this were so, there was no firm foundation anywhere, and all aesthetic judgments were reduced to a matter of taste,—which was of course a very unwelcome conclusion. In the belief that he had found the missing link he planned, toward the end of 1792, a treatise to be known as 'Kallias, or Concerning Beauty'. It was to take the form of a dialogue, to be written in a pleasing style, with a plenty of illustration,—merits to which Kant could lay no claim,—and to review the whole history of aesthetic theorizing.

This plan was finally given up, but a series of rather abstruse letters to Körner, beginning in January, 1793, may be regarded as preparatory studies for the contemplated treatise. Schiller's idea was, evidently, to blaze a private trail through the jungle of Kantian theory, with Körner's critical assistance, and then to return and convert the trail into an agreeable road for the general reader. In the end he chose a different form than that of the Socratic dialogue for the literary presentation of his doctrine, but what he wrote subsequently was based partly at least upon conclusions that he had reached through his correspondence with Körner; wherefore it will be well to look a little more closely, at this point, into his quarrel with the Königsberg philosophy.

As is well known, Kant placed the aesthetic faculty under the jurisdiction of the 'judgment', which he regarded as a sort of connecting link between the pure reason and the practical reason, that is, between cognition and volition. A judgment is teleologic, according to his scheme, if it implies a pre-existing notion to which the object is expected to conform; it is aesthetic when pleasure or pain is produced directly by the object itself. In the good and the agreeable we have an interest,—we will the former and desire the latter. The beautiful, on the other hand, is that which pleases without appealing to any interest (interesseloses Wohlgefalien). This is its character under the category of quality. Under that of quantity it is a universal pleasure; under that of relation, a form of adaptation (Zweckmäszigkeit), with no end present to the mind. Finally, under the fourth category—modality—it is 'necessary', being determined not by any objective criterion, but by the sensus communis of mankind, that is, their agreement in taste.

For Kant, then, the whole matter of aesthetics is a subjective matter. He does not inquire what it is that makes objects beautiful, but how it is that we 'judge' them to be beautiful. While his predecessors made the impression of the beautiful to depend upon objective attributes of form, proportion, harmony, completeness and the like, he insisted that the essence of beauty was to please without reference to any such intellectual concept whatever. His terminology was not very happy, since a judgment that has nothing to do with the intellect is not a judgment at all, but a feeling; nevertheless his system brought out clearly,—and this is perhaps his most important merit in the domain of aesthetics,—the necessity of distinguishing more sharply between the beautiful, on the one hand, and the good and agreeable, on the other. But in expounding his central doctrine, that beauty cannot depend upon a mental concept, he is not quite consistent; for he recognizes 'adaptation' as a form of beauty, and adaptation is a concept of the mind. To meet this difficulty he makes a distinction between free beauty (pulchritudo vaga) and adherent beauty (pulchritudo adhaerens), the latter being mixed up with the good or the desirable. Even a generic or a normative concept was for him fatal to the idea of pure beauty. Thus pure beauty could not be affirmed of a horse, because one inevitably has in his mind an antecedent notion as to how a horse ought to look. Again, there could be no such thing as pure beauty,—at the best only adherent beauty,—in a moral action, since a moral action does not please in and of itself. At the same time Kant held that the highest use of beauty is to symbolize moral truth, and in illustrating the possibilities of this symbolism he indulged in some rather fanciful speculations.

Now we can easily understand that Schiller, notwithstanding all his admiration of Kant and his prompt recognition of the far-reaching importance of Kant's doctrine, could not be perfectly satisfied with a philosophy which decreed that an arabesque is more beautiful than any woman, and that morality cannot be beautiful at all, except in some mystical poetic sense. Nor could he be content with Kant's sensus communis aestheticus, which seemed to leave the beautiful finally a matter of taste. His mental attitude is clearly brought to view in a letter of February 9, 1793, to the Prince of Augustenburg. After speaking warmly of Kant's great service to philosophy, he describes thus the problem which Kant regarded as impossible of solution and which he himself, Schiller, was bold enough to attempt:

When I consider how closely our feeling for the beautiful and the great is connected with the noblest part of our being, it is impossible for me to regard this feeling as a mere subjective play of the emotional faculty, capable of none but empirical rules. It seems to me that beauty too, as well as truth and right, must rest upon eternal foundations, and that the original laws of the reason must also be the laws of taste. It is true that the circumstance of our feeling beauty and not cognizing it seems to cut off all hope of our finding a universal law for it, because every judgment emanating from this source is a judgment of experience. As a rule people accept an explanation of beauty only because it harmonizes in particular cases with the verdict of feeling; whereas, if there were really such a thing as the cognition of beauty from principles, we should trust the verdict of feeling because it coincides with our explanation of the beautiful. Instead of testing and correcting our feelings by means of principles, we test aesthetic principles by our feelings.

So then Schiller attacked his problem in the aforementioned letters to Körner and was soon able to announce his solution: Beauty is nothing else than freedom-in-the-appearance (Freiheit in der Erscheinung).

To make clear the steps by which he arrived at that formula and the wealth of meaning that it contained for him would require a fuller analysis of his argument than there is space for in this chapter. Suffice it to say that he now fully accepts the dogma of Kant that beauty cannot depend upon a mental concept,—the feeling of pleasure is the prior fact. At the same time he has an unshakable conviction that beauty must somehow fall under the laws of reason. He gets rid of the crux by taking the aesthetic faculty away from the jurisdiction of Kant's rather mysterious 'judgment', and turning it over to the 'practical reason'. His argument is that the practical reason demands freedom, just as the 'pure' or theoretic reason demands rationality. Freedom is the form which the practical reason instinctively applies upon presentation of an object. It is satisfied when, and only when, the object is free, autonomous, self-determined. He then propounds his theory that beauty is simply an analogon of moral freedom. On the presentation of an object the practical reason (i.e., the will) may banish for the time being all concepts of the pure reason, may assume complete control and ask no other question than whether the object is free, self-determined, autonomous. If, then, the object appears to be free, to follow no law but its own, the practical reason is satisfied; the effect is pleasurable and we call it beauty. Schiller is careful to point out that it is all a question of appearance: the object is not really free,—since freedom abides only in the supersensual world,—but the practical reason imputes or lends freedom to it. Hence beauty is freedom in the appearance.

In a letter of February 23, 1793, he applies his dogma to an exposition of the relation between nature and art. The problem of the artist in the representation of an object, so the theory runs, is to convey a suggestion of freedom, that is, of not-being-determined-from-without. This he can only do by making the object appear to be determined from within, in other words, to follow its own law. It must have a law and obey it, while seeming to be free. The law of the object is what is disclosed by technique, which is thus the basis of our impression of freedom. Starting from Kant's saying that nature is beautiful when it looks like art, and art beautiful when it looks like nature, Schiller gives a large number of concrete illustrations of his theory. Thus a vase is beautiful when, without prejudice to the vase-idea, it looks like a free play of nature. A birch is beautiful when it is tall and slender, an oak when it is crooked; the shape in either case expressing the nature of the tree when it follows nature's law. 'Therefore', he concludes his illustrations, 'the empire of taste is the empire of freedom; the beautiful world of sense being the happiest symbol of what the moral world should be, and every beautiful object about me being a happy citizen who calls out: Be free like me.'
