It is true that this indication is an internal one, and that there are people who have forgotten what the action of real art is, who expect something else from art (in our society the great majority are in this state), and that therefore such people may mistake for this æsthetic feeling the feeling of divertisement and a certain excitement which they receive from counterfeits of art. But though it is impossible to undeceive these people, just as it is impossible to convince a man suffering from “Daltonism” that green is not red, yet, for all that, this indication remains perfectly definite to those whose feeling for art is neither perverted nor atrophied, and it clearly distinguishes the feeling produced by art from all other feelings.
The chief peculiarity of this feeling is that the receiver of a true artistic impression is so united to the artist that he feels as if the work were his own and not someone else’s,—as if what it expresses were just what he had long been wishing to express. A real work of art destroys, in the consciousness of the receiver, the separation between himself and the artist, nor that alone, but also between himself and all whose minds receive this work of art. In this freeing of our personality from its separation and isolation, in this uniting of it with others, lies the chief characteristic and the great attractive force of art.
If a man is infected by the author’s condition of soul, if he feels this emotion and this union with others, then the object which has effected this is art; but if there be no such infection, if there be not this union with the author and with others who are moved by the same work—then it is not art. And not only is infection a sure sign of art, but the degree of infectiousness is also the sole measure of excellence in art.
The stronger the infection the better is the art, as art, speaking now apart from its subject-matter, i.e. not considering the quality of the feelings it transmits.
And the degree of the infectiousness of art depends on three conditions:—
(1) On the greater or lesser individuality of the feeling transmitted; (2) on the greater or lesser clearness with which the feeling is transmitted; (3) on the sincerity of the artist, i.e. on the greater or lesser force with which the artist himself feels the emotion he transmits.
The more individual the feeling transmitted the more strongly does it act on the receiver; the more individual the state of soul into which he is transferred the more pleasure does the receiver obtain, and therefore the more readily and strongly does he join in it.
The clearness of expression assists infection, because the receiver, who mingles in consciousness with the author, is the better satisfied the more clearly the feeling is transmitted, which, as it seems to him, he has long known and felt, and for which he has only now found expression.
But most of all is the degree of infectiousness of art increased by the degree of sincerity in the artist. As soon as the spectator, hearer, or reader feels that the artist is infected by his own production, and writes, sings, or plays for himself and not merely to act on others, this mental condition of the artist infects the receiver; and, contrariwise, as soon as the spectator, reader, or hearer feels that the author is not writing, singing, or playing for his own satisfaction,—does not himself feel what he wishes to express,—but is doing it for him, the receiver, a resistance immediately springs up, and the most individual and the newest feelings and the cleverest technique not only fail to produce any infection but actually repel.
I have mentioned three conditions of contagiousness in art, but they may all be summed up into one, the last, sincerity, i.e. that the artist should be impelled by an inner need to express his feeling. That condition includes the first; for if the artist is sincere he will express the feeling as he experienced it. And as each man is different from everyone else, his feeling will be individual for everyone else; and the more individual it is,—the more the artist has drawn it from the depths of his nature,—the more sympathetic and sincere will it be. And this same sincerity will impel the artist to find a clear expression of the feeling which he wishes to transmit.
