A work that aspires, however humbly, to the condition of art should carry its justification in every line. And art itself may be defined as a single-minded attempt to render the highest kind of justice to the visible universe, by bringing to light the truth, manifold and one, underlying its every aspect. It is an attempt to find in its forms, in its colours, in its light, in its shadows, in the aspects of matter and in the facts of life what of each is fundamental, what is enduring and essential—their one illuminating and convincing quality—the very truth of their existence. The artist, then, like the thinker or the scientist, seeks the truth and makes his appeal. Impressed by the aspect of the world the thinker plunges into ideas, the scientist into facts—whence, presently, emerging they make their appeal to those qualities of our being that fit us best for the hazardous enterprise of living. They speak authoritatively to our common-sense, to our intelligence, to our desire of peace or to our desire of unrest; not seldom to our prejudices, sometimes to our fears, often to our egoism—but always to our credulity. And their words are heard with reverence, for their concern is with weighty matters: with the cultivation of our minds and the proper care of our bodies, with the attainment of our ambitions, with the perfection of the means and the glorification of our precious aims. It is otherwise with the artist. Confronted by the same enigmatical spectacle the artist descends within himself, and in that lonely region of stress and strife, if he be deserving and fortunate, he finds the terms of his appeal. His appeal is made to our less obvious capacities: to that part of our nature which, because of the warlike conditions of existence, is necessarily kept out of sight within the more resisting and hard qualities—like the vulnerable body within a steel armour. His appeal is less loud, more profound, less distinct, more stirring—and sooner forgotten. Yet its effect endures forever. The changing wisdom of successive generations discards ideas, questions facts, demolishes theories. But the artist appeals to that part of our being which is not dependent on wisdom; to that in us which is a gift and not an acquisition—and, therefore, more permanently enduring. He speaks to our capacity for delight and wonder, to the sense of mystery surrounding our lives; to our sense of pity, and beauty, and pain; to the latent feeling of fellowship with all creation—and to the subtle but invincible conviction of solidarity that knits together the loneliness of innumerable hearts, to the solidarity in dreams, in joy, in sorrow, in aspirations, in illusions, in hope, in fear, which binds men to each other, which binds together all humanity—the dead to the living and the living to the unborn.
