At all events, if it is accidental with regard to the object, that the understanding associates, at the representation of this object, one of its own ideas with it, it is not the less necessary for the subject which represents it to attach to such a representation such an idea. This idea, and the sensuous indication which corresponds to it in the object, ought to be one with the other in such relation, that the understanding be forced to this association by its own immutable laws; the understanding then must have in itself the reason which leads it to associate exclusively a certain phenomenon with a certain determined idea, and, reciprocally, the object should have in itself the reason for which it exclusively provokes that idea and not another. As to knowing what the idea can be which the understanding carries into the beautiful, and by what objective property the object gifted with beauty can be capable of serving as symbol to this idea, is then a question much too grave to be solved here in passing, and I reserve this examination for an analytical theory of the beautiful.
The architectonic beauty of man is then, in the way I have explained it, the visible expression of a rational conception, but it is so only in the same sense and the same title as are in general all the beautiful creations of nature. As to the degree, I agree that it surpasses all the other beauties; but with regard to kind, it is upon the same rank as they are, because it also manifests that which alone is perceptible of its subject, and it is only when we represent it to ourselves that it receives a super-sensuous value.
If the ends of creation are marked in man with more of success and of beauty than in the organic beings, it is to some extent a favor which the intelligence, inasmuch as it dictated the laws of the human structure, has shown to nature charged to execute those laws. The intelligence, it is true, pursues its end in the technique of man with a rigorous necessity, but happily its exigencies meet and accord with the necessary laws of nature so well, that one executes the order of the other whilst acting according to its own inclination.
But this can only be true respecting the architectonic beauty of man, where the necessary laws of physical nature are sustained by another necessity, that of the teleological principle which determines them. It is here only that the beautiful could be calculated by relation to the technique of the structure, which can no longer take place when the necessity is on one side alone, and the super-sensuous cause which determines the phenomenon takes a contingent character. Thus, it is nature alone who takes upon herself the architectonic beauty of man, because here, from the first design, she had been charged once for all by the creating intelligence with the execution of all that man needs in order to arrive at the ends for which he is destined, and she has in consequence no change to fear in this organic work which she accomplishes.
But man is moreover a person—that is to say, a being whose different states can have their cause in himself, and absolutely their last cause; a being who can be modified by reason that he draws from himself. The manner in which he appears in the world of sense depends upon the manner in which he feels and wills, and, consequently, upon certain states which are freely determined by himself, and not fatally by nature.
If man were only a physical creature, nature, at the same time that she establishes the general laws of his being, would determine also the various causes of application. But here she divides her empire with free arbitration; and, although its laws are fixed, it is the mind that pronounces upon particular cases.
The domain of mind extends as far as living nature goes, and it finishes only at the point at which organic life loses itself in unformed matter, at the point at which the animal forces cease to act. It is known that all the motive forces in man are connected one with the other, and this makes us understand how the mind, even considered as principle of voluntary movement, can propagate its action through all organisms. It is not only the instruments of the will, but the organs themselves upon which the will does not immediately exercise its empire, that undergo, indirectly at least, the influence of mind; the mind determines then, not only designedly when it acts, but again, without design, when it feels.
From nature in herself (this result is clearly perceived from what precedes) we must ask nothing but a fixed beauty, that of the phenomena that she alone has determined according to the law of necessity. But with free arbitration, chance (the accidental), interferes in the work of nature, and the modifications that affect it thus under the empire of free will are no longer, although all behave according to its own laws, determined by these laws. From thence it is to the mind to decide the use it will make of its instruments, and with regard to that part of beauty which depends on this use, nature has nothing further to command, nor, consequently, to incur any responsibility.
And thus man by reason that, making use of his liberty, he raises himself into the sphere of pure intelligences, would find himself in danger of sinking, inasmuch as he is a creature of sense, and of losing in the judgment of taste that which he gains at the tribunal of reason. This moral destiny, therefore, accomplished by the moral action of man, would cost him a privilege which was assured to him by this same moral destiny when only indicated in his structure; a purely sensuous privilege, it is true, but one which receives, as we have seen, a signification and a higher value from the understanding. No; nature is too much enamored with harmony to be guilty of so gross a contradiction, and that which is harmonious in the world of the understanding could not be rendered by a discord in the world of sense.
As soon, then, as in man the person, the moral and free agent, takes upon himself to determine the play of phenomena, and by his intervention takes from nature the power to protect the beauty of her work, he then, as it were, substitutes himself for nature, and assumes in a certain measure, with the rights of nature, a part of the obligations incumbent on her. When the mind, taking possession of the sensuous matter subservient to it, implicates it in his destiny and makes it depend on its own modifications, it transforms itself to a certain point into a sensuous phenomenon, and, as such, is obliged to recognize the law which regulates in general all the phenomena. In its own interest it engages to permit that nature in its service, placed under its dependence, shall still preserve its character of nature, and never act in a manner contrary to its anterior obligations. I call the beautiful an obligation of phenomena, because the want which corresponds to it in the subject has its reason in the understanding itself, and thus it is consequently universal and necessary. I call it an anterior obligation because the senses, in the matter of beauty, have given their judgment before the understanding commences to perform its office.
