“All money is imaginary," answered the Calcatrix simply. "Money is magic everyone agrees to pretend is not magic. Observe! You treat it like magic, wield it like magic, fear it like magic! Why should a body with more small circles of copper or silver or gold than anyone else have an easy life full of treats every day and sleeping in and other people bowing down? The little circles can't get up and fight a battle or make a supper so splendid you get full just by looking at it or build a house of a thousand gables. They can do those things because everyone agrees to give them power. If everyone agreed to stop giving power to pretty metals and started giving it to thumbnails or mushroom caps or roof shingles or first kisses or tears or hours or puffin feathers, those little circles would just lay there tarnishing in the rain and not making anyone bow their noses down to the ground or stick them up in the air.”
