authority of criticism is not absolute, but varies with the powers and range of the individual critic, and that at the last he must find his standard within himself. There are, of course, certain standards of excellence recognized universally and certain principles of taste of universal validity; and to these standards and these principles must be referred our individual estimates for comparison and correction. Given a native sensibility to the worth of life and to the appeal of beauty, the justice of our estimate will be in proportion to the extent of our knowledge of life and of our contact with art. Our individual judgment, therefore, must be controlled by experience,--our momentary judgments by the sum of our own experience, and our total judgment by universal experience. In all sound criticism and right appreciation there must be a basis of disciplined taste. We must guard ourselves against whims and caprice, even our own. So the individual may not cut loose altogether from external standards. But these must be brought into relation to his personal needs and applied with reference to his own standard. Finally, for his own uses, the individual has the right to determine the meaning and value to him of any work of art in the measure that it links itself with his own actual or possible experience and becomes for him a revelation of fuller life. For beauty is the power possessed by objects to quicken us with a sense of larger personality; and art, whether the arts of form or of representation, is the material bodying forth of beauty as the artist has perceived it and the means by which his emotion in its presence is communicated. Upon this conception of beauty and this interpretation of the scope and function of art rests the justice of the personal estimate. VII BEAUTY AND COMMON LIFE
