Nature is incomplete. She leaves man to provide for himself his raiment, shelter, and surroundings. Nature in her works throws out suggestions of beauty, rather than its perfect and complete embodiment. Her gold is imbedded in the rock. Her creations are limited by the particular material and the narrow conditions which are at her disposal at a given time and place. To seize the pure ideal of beauty which Nature suggests, but never quite realizes; to select from the universe of space and the eternity of time those materials and forms which are perfectly adapted to portray the ideal beauty; to clothe the abodes and the whole physical environment of man with that beauty which is suggested to us in sky and stream and field and flower; to present to us for perpetual contemplation the form and features of ideal manhood and womanhood; to hold before our imagination the deeds of brave men, and the devotion of saintly women; to thrill our hearts with the victorious struggle of the hero and the death-defying passion of the lover;--this is the mission and the significance of art. Art is creative. The artist is a co-worker with God. To his hands is committed the portion of the world which God has left unfinished--the immediate environment of man. We cannot live in the fields, like beasts and savages. Art has for its purpose to make the rooms and houses and halls and streets and cities in which civilized men pass their days as beautiful and fair, as elevating and inspiring, as the fields and forests in which the primeval savage roamed. More than that, art aims to fill these rooms and halls and streets of ours with forms and symbols which shall preserve, for our perpetual admiration and inspiration, all that is purest and noblest and sweetest in that long struggle of man up from his savage to his civilized estate. THE DUTY. +Beauty is the outward and visible sign of inward perfection, completeness, and harmony.+--In an object of beauty there is neither too little nor too much; nothing is out of place; nothing is without its contribution to the perfect whole. Each part is at once means and end to every other. Hence its perfect symmetry; its regular proportions; its strict conformity to law. The mind of man can find rest and satisfaction in nothing short of perfection; and consequently our hearts are never satisfied until they behold beauty, which is perfection's crown and seal. Without it one of the deepest and divinest powers of our nature remains dwarfed, stifled, and repressed.
