From the antagonism of the two impulsions, and from the association of two opposite principles, we have seen beauty to result, of which the highest ideal must therefore be sought in the most perfect union and equilibrium possible of the reality and of the form. But this equilibrium remains always an idea that reality can never completely reach. In reality, there will always remain a preponderance of one of these elements over the other, and the highest point to which experience can reach will consist in an oscillation between two principles, when sometimes reality and at others form will have the advantage. Ideal beauty is therefore eternally one and indivisible, because there can only be one single equilibrium; on the contrary, experimental beauty will be eternally double, because in the oscillation the equilibrium may be destroyed in two ways—this side and that.
I have called attention in the foregoing letters to a fact that can also be rigorously deduced from the considerations that have engaged our attention to the present point; this fact is that an exciting and also a moderating action may be expected from the beautiful. The tempering action is directed to keep within proper limits the sensuous and the formal impulsions; the exciting, to maintain both of them in their full force. But these two modes of action of beauty ought to be completely identified in the idea. The beautiful ought to temper while uniformly exciting the two natures, and it ought also to excite while uniformly moderating them. This result flows at once from the idea of a correlation, in virtue of which the two terms mutually imply each other, and are the reciprocal condition one of the other, a correlation of which the purest product is beauty. But experience does not offer an example of so perfect a correlation. In the field of experience it will always happen more or less that excess on the one side will give rise to deficiency on the other, and deficiency will give birth to excess. It results from this that what in the beau-ideal is only distinct in the idea is different in reality in empirical beauty. The beau-ideal, though simple and indivisible, discloses, when viewed in two different aspects, on the one hand, a property of gentleness and grace, and on the other, an energetic property; in experience there is a gentle and graceful beauty and there is an energetic beauty. It is so, and it will be always so, so long as the absolute is enclosed in the limits of time, and the ideas of reason have to be realized in humanity. For example, the intellectual man has the ideal of virtue, of truth, and of happiness; but the active man will only practise virtues, will only grasp truths, and enjoy happy days. The business of physical and moral education is to bring back this multiplicity to unity, to put morality in the place of manners, science in the place of knowledge; the business of aesthetic education is to make out of beauties the beautiful.
Energetic beauty can no more preserve a man from a certain residue of savage violence and harshness than graceful beauty can secure him against a certain degree of effeminacy and weakness. As it is the effect of the energetic beauty to elevate the mind in a physical and moral point of view and to augment its momentum, it only too often happens that the resistance of the temperament and of the character diminishes the aptitude to receive impressions, that the delicate part of humanity suffers an oppression which ought only to affect its grosser part, and that this coarse nature participates in an increase of force that ought only to turn to the account of free personality. It is for this reason that, at the periods when we find much strength and abundant sap in humanity, true greatness of thought is seen associated with what is gigantic and extravagant, and the sublimest feeling is found coupled with the most horrible excess of passion. It is also the reason why, in the periods distinguished for regularity and form, nature is as often oppressed as it is governed, as often outraged as it is surpassed. And as the action of gentle and graceful beauty is to relax the mind in the moral sphere as well as the physical, it happens quite as easily that the energy of feelings is extinguished with the violence of desires, and that character shares in the loss of strength which ought only to affect the passions. This is the reason why, in ages assumed to be refined, it is not a rare thing to see gentleness degenerate into effeminacy, politeness into platitude, correctness into empty sterility, liberal ways into arbitrary caprice, ease into frivolity, calm into apathy, and, lastly, a most miserable caricature treads on the heels of the noblest, the most beautiful type of humanity. Gentle and graceful beauty is therefore a want to the man who suffers the constraint of manner and of forms, for he is moved by grandeur and strength long before he becomes sensible to harmony and grace. Energetic beauty is a necessity to the man who is under the indulgent sway of taste, for in his state of refinement he is only too much disposed to make light of the strength that he retained in his state of rude savagism.
I think I have now answered and also cleared up the contradiction commonly met in the judgments of men respecting the influence of the beautiful, and the appreciation of aesthetic culture. This contradiction is explained directly we remember that there are two sorts of experimental beauty, and that on both hands an affirmation is extended to the entire race, when it can only be proved of one of the species. This contradiction disappears the moment we distinguish a twofold want in humanity to which two kinds of beauty correspond. It is therefore probable that both sides would make good their claims if they come to an understanding respecting the kind of beauty and the form of humanity that they have in view.
Consequently in the sequel of my researches I shall adopt the course that nature herself follows with man considered from the point of view of aesthetics, and setting out from the two kinds of beauty, I shall rise to the idea of the genus. I shall examine the effects produced on man by the gentle and graceful beauty when its springs of action are in full play, and also those produced by energetic beauty when they are relaxed. I shall do this to confound these two sorts of beauty in the unity of the beau-ideal, in the same way that the two opposite forms and modes of being of humanity are absorbed in the unity of the ideal man.
