We test every organic desire to see whether it be the outcome of a legitimate need or the consequence of an aberration; whether its satisfaction be beneficial or pernicious to the organism. We distinguish the healthy from the diseased impulse, and demand that the latter be combated. If the desire seeks its satisfaction in an activity acting upon others, then we examine to see if this activity is reconcilable with the existence and prosperity of society, or dangerous to it. The activity imperilling society offends against law and custom, which are nothing but an epitome of the temporary notions of society concerning what is beneficial and what is pernicious to it.

Notions healthy and diseased, moral and immoral, social or anti-social, are as valid for art as for every other human activity, and there is not a scintilla of reason for regarding a work of art in any other light than that in which we view every other manifestation of an individuality.

It is easily conceivable that the emotion expressed by the artist in his work may proceed from a morbid aberration, may be directed, in an unnatural, sensual, cruel manner, to what is ugly or loathsome. Ought we not in this case to condemn the work and, if possible, to suppress it? How can its right to exist be justified? By claiming that the artist was sincere when he created it, that he gave back what was really existing in him, and for that reason was subjectively justified in his artistic expansion? But there is a candour which is wholly inadmissible. The dipsomaniac and clastomaniac are sincere when they respectively drink or break everything within reach. We do not, however, acknowledge their right to satisfy their desire. We prevent them by force. We put them under guardianship, although their drunkenness and destructiveness may perhaps be injurious to no one but themselves. And still more decidedly does society oppose itself to the satisfaction of those cravings which cannot be appeased without violently acting upon others. The new science of criminal anthropology admits without dispute that homicidal maniacs, certain incendiaries, many thieves and vagabonds, act under an impulsion; that through their crimes they satisfy an organic craving; that they outrage, kill, burn, idle, as others sit down to dinner, simply because they hunger to do so; but in spite of this and because of this, it demands that the appeasing of the sincere longings of these degenerate creatures be prevented by all means, and, if needs be, by their complete suppression. It never occurs to us to permit the criminal by organic disposition to ‘expand’ his individuality in crime, and just as little can it be expected of us to permit the degenerate artist to expand his individuality in immoral works of art. The artist who complacently represents what is reprehensible, vicious, criminal, approves of it, perhaps glorifies it, differs not in kind, but only in degree, from the criminal who actually commits it. It is a question of the intensity of the impulsion and the resisting power of the judgment, perhaps also of courage and cowardice; nothing else. If the actual law does not treat the criminal by intention so rigorously as the criminal in act, it is because criminal law pursues the deed, and not the purpose; the objective phenomenon, not its subjective roots. The Middle Ages had places of sanctuary where criminals could not be molested for their misdemeanours. Modern law has done away with this institution. Ought art to be at present the last asylum to which criminals may fly to escape punishment? Are they to be able to satisfy, in the so-called ‘temple’ of art, instincts which the policeman prevents them from appeasing in the street? I do not see how a privilege so inimical to society can be willingly defended.

I am far from sharing Ruskin’s opinion that morality alone, and nothing else, can be demanded of a work of art. Morality alone is not sufficient. Otherwise religious tracts would be the finest literature, and the well-known coloured casts of sacred subjects turned out wholesale in Munich factories would be the choicest sculpture. Excellence of form maintains its rights in all the arts, and gives to the finest creation its artistic value. Hence the work need not be moral. More accurately, it need not be designed expressly to preach virtue and the fear of God, and to be destined for the edification of devotees. But between a work without sanctified aim and one of wilful immorality there is a world of difference. A work which is indifferent from a moral point of view will not be equally attractive or satisfying to all minds, but it will offend and repel no one. An explicitly immoral work excites in healthy persons the same feelings of displeasure and disgust as the immoral act itself, and the form of the work can change nothing of this. Most assuredly morality alone does not give beauty to a work of art. But beauty without morality is impossible.

We now come to the second argument with which the Æsthetes wish to defend the right of the artist to immorality. The work of art, they say, need only be beautiful. Beauty lies in the form. Hence the content is a matter of indifference. This may be vice and crime; but it cannot derogate from the excellences of form if these be present.

He alone can venture to advance such principles who is without the least inkling of the psycho-physiology of the æsthetic feelings. Everyone who has studied this subject in the least knows that two kinds of the beautiful are distinguished—the sensuously-beautiful and the intellectually-beautiful. We feel those phenomena to be beautiful, the sense-perception of which is accompanied by a feeling of pleasure—e.g., a particular colour, perhaps a pure red, or a harmony; nay, even a single note with its severally indistinguishable but synchronous overtones. The researches of Helmholtz[309] and Blaserna[310] have thrown light on the cause of the feeling of pleasure connected with certain acoustic perceptions, while those of Brücke[311] have led to similar results with regard to the mechanism of the feelings of pleasure following optical impressions. It is a question of discernment by the sensory nerves of definite simple numerical relations in the vibrations of matter or of ether. We know less concerning the causes of the pleasures connected with smell and touch; yet here also it seems to be a question of more or less strong impressions, hence equally of quantities—i.e., of numbers. The ultimate cause of all these feelings is that certain modes of vibrations are in accord with the structure of the nerves, are easy for them and leave them in order, while other modes disturb the arrangement of the nerve particles, often costing the nerves an effort, often dangerous to their existence or at least their functioning, to restore them to their natural order. The former will be felt as pleasure, the latter as discomfort, and even as pain. With the sensuously-beautiful there can be no question of morality, for it exists as perception only, and does not rise to the rank of representation.

Above the sensuously-beautiful stands the intellectually-beautiful, no longer consisting of mere perceptions, but of representations, of concepts and judgments, with their accompanying emotions elaborated in the unconscious. The intellectually-beautiful must also awaken feelings of pleasure, to be perceived as beautiful; and, as above explained, with feelings of pleasure are united, in healthy, fully-developed human beings equipped with the social instinct (altruism), only those ideas the content whereof is conducive to the existence and prosperity of the individual being, society, or species. Now, that which is favourable to the life and prosperity of the individual and of the species is precisely that which we call moral.

From this it results by an iron necessity that a work which awakens no feelings of pleasure cannot be beautiful, and that it can awaken no feelings of pleasure if it is not moral, and we arrive at the final conclusion, that morality and beauty are in their innermost essence identical. It were not false to assert that beauty is statical repose, and morality beauty in action.

This is only apparently contradicted by the fact that what is incontestably ugly and bad may also be agreeable, and hence awaken feelings of pleasure. The mental process set up by percepts and ideas is not, in this case, so simple and direct as with respect to the beautiful and the good. Associations sometimes of a highly complex nature must first be put into activity, finally, however, to lead to the single great result, viz., the awakening of feelings of pleasure. The well-known Aristotelian catharsis, purging or purification, explains how tragedy, though it offers the spectacle of pain and ruin, finally produces an agreeable effect. The representation of deserved misfortune awakens ideas of justice, a moral, agreeable idea; and even that of unmerited misfortune gives rise to pity, in itself a feeling of pain, though, in its quality of a racial instinct, beneficial and therefore not only moral, but, in its final essence, agreeable. When Valdez, in his famous picture of the Caridad de Sevilla, shows us an open coffin in which lies the corpse of an arch-bishop in full vestments, swarming with worms, this spectacle is in itself undeniably repulsive. Nevertheless it permits us at once to recognise the emotion which the painter wished to express, viz., his feeling of the nothingness of all earthly possessions and honours, the frailty of man in the face of the primeval power of Nature. It is the same emotion embodied by Holbein in his ‘Dance of Death,’ not so profoundly and passionately as by the Spaniard with his stronger feelings, but with self-mockery and bitterness. The same emotion is heard, somewhat less gloomily and with more of a melancholy resignation, in Mozart’s Requiem. In the idea of the contrast between the insignificance of individual life and the vastness and eternity of Nature, there mingles itself an element of the sublime, of which the idea, as the choicest form of activity in the highest brain-centres, is united with feelings of pleasure.

Another circumstance in the plastic arts has to be considered. In works of sculpture and painting a broad separation is possible between the form and the content, between the sensuous and the moral. A painting, a group, may represent the most immoral and most criminal incident; nevertheless, the individual constituent parts—the atmosphere, the harmonies of colour, the human figures—may be beautiful in themselves, and the connoisseur may derive enjoyment from them without dwelling on the subject of the work. The engravings in the Editions des fermiers généraux of the last century, the works in marble and bronze of the pornographic museum at Naples, are, in a measure, repulsively immoral, because they represent unnatural vice. In themselves, however, they are excellently executed, and are accessible to a mode of contemplation which disregards their idea and keeps in view only the perfection of their form. Here, therefore, the impression of the work of art is a mixture of disgust for the subject treated, and enjoyment of the beauty of the several figures and their attitudes—painted, drawn, or modelled. The feeling of pleasure may preponderate, and the work, in spite of its depravity, produce, not a repellent, but an attractive effect. It is the same in nature. If that which is pernicious and frightful is sometimes felt to be beautiful, it is because it contains certain features and elements which have no cogent reference to the frightful or pernicious character of the whole, and can hence in themselves operate æsthetically. The hammer-headed viper is beautiful on account of its metallic lustre; the tiger for its strength and suppleness; the foxglove (Digitalis) for its graceful form and rich rosy hue. The noxiousness of the snake does not lie in its copper-red dorsal bands, nor the terribleness of the beast of prey in its graceful appearance, nor the danger of the poisonous plant in the form and colour of its blossoms. In these cases the sensuously-beautiful outweighs the morally-repulsive, because it is more immediately present, and, in the collective impression, allows the feelings of pleasure to predominate. The spectacle of the display of strength and resolution is equally a beautiful one, on account of the ideas of organic efficiency awakened by it. Would this, however, be thought beautiful if one could see how an assassin overpowers a victim who is resisting violently, hurls him to the ground and butchers him? Certainly not; for before such a picture it is no longer possible to separate the display of strength, beautiful in itself, from its aim, and to enjoy the former regardless of the latter.
