““At certain epochs, man has felt conscious of something about himself - body and spirit - which was outside the day-to-day struggle for existence and the night-to-night struggle with fear; and he has felt the need to develop these qualities of thought and feeling so that they might approach as nearly as possible to an ideal of perfection - reason, justice, physical beauty, all of them in equilibrium. He has managed to satisfy this need in various ways - through myths, through dance and song, through systems of philosophy and through the order that he has imposed upon the visible world.””
