"That's the difference between the serious artist and the craftsman--the craftsman can take material and because of his abilities do a professional job of it. The serious artist, like Proust, is like an object caught by a wave and swept to shore. He's obsessed by his material; it's like a venom working in his blood and the art is the antidote."

Rational behavior ... depends upon a ceaseless flow of data from the environment. It depends upon the power of the individual to predict, with at least a fair success, the outcome of his own actions. To do this, he must be able to predict how the environment will respond to his acts. Sanity, itself, thus hinges on man's ability to predict his immediate, personal future on the basis of information fed him by the environment.
