Rubbish! I like it when they talk nonsense! talking nonsense is the sole privilege mankind possesses over the other organisms. It's by talking nonsense that one gets to the truth! I talk nonsense, therefore I'm human. Not one single truth has ever been arrived at without people having first talked a dozen reams of nonsense ... To talk nonsense in one's own way is almost better than to talk a truth that's someone else's; in the first instance you behave like a human being, while in the second you are merely being a parrot.
