“What’s so phony nowadays is all this familiarity. Pretending there isn’t any difference between people. . . . If you and I are no different, what do we have to give each other? How can we ever be friends?”
And now an hour, maybe, has passed. And they are both drunk: Kenny fairly, George very. But George is drunk in a good way, and one that he seldom achieves. He tries to describe to himself what this kind of drunkenness is like. Well — to put it very crudely — it’s like Plato; it’s a dialogue. A dialogue between two people. Yes, but not a Platonic dialogue in the hair-splitting, word-twisting, one-up-to-me sense; not a mock-humble bitching match; not a debate on some dreary set theme. You can talk about anything and change the subject as often as you like. In fact, what really matters is not what you talk about, but the being together in this particular relationship. George can’t imagine having a dialogue of this kind with a woman, because women can only talk in terms of the personal. A man of his own age would do, if there was some sort of polarity; for instance, if he was a Negro. You and your dialogue-partner have to be somehow opposites. Why? Because you have to be symbolic figures — like, in this case, Youth and Age. Why do you have to be symbolic? Because the dialogue is by its nature impersonal. It’s a symbolic encounter. It doesn’t involve either party personally. That’s why, in a dialogue, you can say absolutely anything. Even the closest confidence, the deadliest secret, comes out objectively as a mere metaphor or illustration which could never be used against you.
