The Mind

Caterpillar: Who… are… you?
Alice: Why, I.. I.. I hardly know, sir. I’ve changed so many times since this morning, you see and…
Caterpillar: I do not see. Explain yourself.
Alice: I’m afraid I cant explain myself, sir, because I’m not myself, you know.
Caterpillar: I do not know.
Alice: Well, I can’t put it any more clearly for it isn’t clear to me.
Caterpillar: You? Who are you?

...

Alice: Which way should I go?
Cheshire: That depends on where you are going.
Alice: I don't know.
Cheshire: Then it doesn't matter which way you go.
