Nowhere in a zoo can a stranger encounter the look of an animal. At the most, the animal’s gaze flickers and passes on. They look sideways. They look blindly beyond. They scan mechanically. … That look between animal and man, which may have played a crucial role in the development of human society, and with which, in any case, all men had always lived until less than a century ago, has been extinguished. Looking at each animal, the unaccompanied zoo visitor is alone.

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. Not of course our awareness of our potentiality as artists ourselves. But a way of looking at the world implies a certain relationship with the world, and every relationship implies action. The kind of actions implied vary a great deal. ... A work of art can, to some extent, increase an awareness of different potentialities in different people. The important point is that a valid work of art promises in some way or another the possibility of an increase, an improvement. Nor need the word 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 his subject. Goya's way of looking at a massacre amounts to the contention that we ought to be able to do without massacres.

What do these conventions mean? What does a nude signify? It is not sufficient to answer these questions merely in terms of the art-form, for it is quite clear that the nude also relates to lived sexuality.
To be naked is to be oneself.
To be nude is to be seen naked by others and yet not recognized for oneself. A naked body has to be seen as an object in order to become a nude. (The sight of it as an object stimulates the use of it as an object.) Nakedness reveals itself. Nudity is placed on display.
To be naked is to be without disguise.
To be on display is to have the surface of one’s own skin, the hairs of one’s own body, turned into a disguise which, in that situation, can never be discarded. The nude is condemned to never being naked. Nudity is a form of dress.
