Creatures are cups. The sciences and the arts and all branches of knowledge are inscriptions around the outside of the cups. When a cup shatters, the writing can no longer be read. The wine's the thing! The wine that's held in the mold of these physical cups. Drink the wine and know what lasts and what to love. The man who truly asks must be sure of two things: One, that he's mistaken in what he's doing or thinking now. And two, that there is a wisdom he doesn't know yet. Asking is half of knowing.
