Yet why should an artist’s way of looking at the world have any meaning for us? Why does it give us pleasure? Because, I believe, it increases our awareness of our own potentiality…a way of looking at the world implies a certain relationship with the world, and every relationship implies action…A valid work of art promises in some way or another the possibility of an increase, an improvement. Nor need the work be optimistic to achieve this; indeed, its subject may be tragic. For it is not the subject that makes the promise, it is the artist’s way of viewing the subject.
