"The first is the critic of art as life, who judges the work by its truth to nature. He is commonest among practical men, politicians, and moralists; he is the man of conscience. The second is the critic of art as art, who judges the work by its beauty and form. He is rarer, for he presupposes a sense of harmony and the love of style. The first asks whether the work teaches anything; the second asks whether the work pleases. The first is concerned with utilitarian ends, the second with artistic ends."
