Writing itself is one of the great, free human activities. There is scope for individuality, and elation, and discovery. In writing, for the person who follows with trust and forgiveness what occurs to him, the world remains always ready and deep, an inexhaustible environment, with the combined vividness of an actuality and flexibility of a dream. Working back and forth between experience and thought, writers have more than space and time can offer. They have the whole unexplored realm of human vision.
