"This, I believe, is the appropriate image of human intercourse -- appropriate because it recognizes the qualities, the diversities, and the proper relationships of human utterances. As civilized human beings, we are the inheritors, neither of an inquiry about ourselves and the world, nor of an accumulating body of information, but of a conversation, begun in the primeval forests and extended and made more articulate in the course of centuries. It is a conversation which goes on both in public and within each of ourselves."
