II.
Perhaps the best way of expounding my reasons will be to follow the process by which I reached them; for so far from having started with the theory of Diotima, I found the theory of Diotima, when I re-read it accidentally after many years' forgetfulness, to bring to convergence the result of my gradual experience.
Thinking about the Hermes of Olympia, and the fact that so far he is pretty well the only Greek statue which historical evidence unhesitatingly gives us as an original masterpiece, it struck me that, could one become really familiar with him, could eye and soul learn all the fulness of his perfection, we should have the true starting-point for knowledge of the antique, for knowledge, in great measure, of all art.
Yes, and of more than art, or rather of art in more than one relation.
Is this a superstition, a mere myth, perhaps, born of words? I think not. Surely if we could really arrive at knowing such a masterpiece, so as to feel rather than see its most intimate organic principles, and the great main reasons separating it from all inferior works and making it be itself: could we do this, we should know not merely what art is and should be, but, in a measure, what life should be and might become: what are the methods of true greatness, the sensations of true sanity.
It would teach us the eternal organic strivings and tendencies of our soul, those leading in the direction of life, leading away from death.
If this seems mere allegory and wild talk, let us look at facts and see what art is. For is not art inasmuch as untroubled by the practical difficulties of existence, inasmuch as the free, unconscious attempt of all nations and generations to satisfy, outside life, those cravings which life still leaves unsatisfied—is not art a delicate instrument, showing in its sensitive oscillations the most intimate movements and habits of the soul? Does it not reveal our most recondite necessities and possibilities, by sifting and selecting, reinforcing or attenuating, the impressions received from without; showing us thereby how we must stand towards nature and life, how we must feel and be?
And this most particularly in those spontaneous arts which, first in the field, without need of adaptations of material or avoidance of the already done, without need of using up the rejected possibilities of previous art, or awakening yet unknown emotions, are the simple, straightforward expression, each the earliest satisfactory one in its own line, of the long unexpressed, long integrated, organic wants and wishes of great races of men: the arts, for instance, which have given us that Hermes, Titian's pictures, and Michael Angelo's and Raphael's frescoes; given us Bach, Gluck, Mozart, the serener parts of Beethoven, music of yet reserved pathos, braced, spring-like strength, learned, select: arts which never go beyond the universal, averaged expression of the soul's desires, because the desires themselves are sifted, limited to the imperishable and unchangeable, like the artistic methods which embody them, reduced to the essential by the long delay of utterance, the long—century long—efforts to utter.
Becoming intimate with such a statue as the Olympian Hermes, and comparing the impressions received from it with the impressions both of inferior works of the same branch of art and with the impressions of equally great works—pictures, buildings, musical compositions—of other branches of art, becoming conversant with the difference between an original and a copy, great art and poor art, we gradually become aware of a quality which exists in all good art and is absent in all bad art, and without whose presence those impressions summed up as beauty, dignity, grandeur, are never to be had. This peculiarity, which most people perceive and few people define—explaining it away sometimes as truth, or taking it for granted under the name of quality—this peculiarity I shall call for convenience' sake harmony; for I think you will all of you admit that the absence or presence of harmony is what distinguishes bad art from good. Harmony, in this sense—and remember that it is this which connoisseurs most usually allude to as quality—harmony may be roughly defined as the organic correspondence between the various parts of a work of art, the functional interchange and interdependence thereof. In this sense there is harmony in every really living thing, for otherwise it could not live. If the muscles and limbs, nay, the viscera and tissues, did not adjust themselves to work together, if they did not in this combination establish a rhythm, a backward-forward, contraction-relaxation, taking-in-giving-out, diastole-systole in all their movements, there would be, instead of a living organism, only an inert mass. In all living things, and just in proportion as they are really alive (for in most real things there is presumably some defect of rhythm tending to stoppage of life), there is bound to be this organic interdependence and interchange. Natural selection, the survival of such individuals and species as best work in with, are most rhythmical to, their surroundings—natural selection sees to that.
