Alice : But I don’t want to go among mad people.
The Cat : Oh, you can’t help that. We’re all mad here. I’m mad. You’re mad.
Alice : How do you know I’m mad ?
The Cat : You must be. Or you wouldn’t have come here.
Alice : And how do you know that you’re mad ?
The Cat : To begin with, a dog’s not mad. You grant that ?
Alice : I suppose so,
The Cat : Well, then, you see, a dog growls when it’s angry, and wags its tail when it’s pleased. Now I growl when I’m pleased, and wag my tail when I’m angry. Therefore I’m mad..

The Duchess : Be what you would seem to be — or, if you’d like it put more simply — Never imagine yourself not to be otherwise than what it might appear to others that what you were or might have been was not otherwise than what you had been would have appeared to them to be otherwise.

We’re all mad here. I’m mad. You’re mad.

the world is mad
