The writer, perhaps more than any of his fellow artists, has access to the human subconscious. His words sink deep, shaping dreams, easing the pain of loneliness, banishing incantations and omens, keeping alive the memories of the race, proviving intimations of immortality, nourishing great anticipations, sharpening the instinct for justice, and imparting respect for the fragility of life. These functions are essential for human evolution. Without them, civilization becomes brittle and breaks easily. Society must be measured, therefore, not just by its display of power but by its attention to the conditions of creativity and its acceptance of human sovereignty as the highest value.
