“Real magic can never be made by offering someone else's liver. You must tear out your own, and not expect to get it back.”

“The magic on you is only magic and will vanish a soon as you are free, but the enchantment of error that you put on me I must wear forever in your eyes. We are not always what we seem, and hardly ever what we dream.”

“Don't look back and don't run. You must never run from anything immortal. It attracts their attention.”

“No," she said, answering his eyes. "I can never regret."[...]"I can sorrow," she offered gently, "but it's not the same thing.”

“Because that world's gone. The world where people walked around whistling that music. All the madrigal singers in the world can't make that other one real again. It's like dinosaurs. We can put them back together perfectly, bone for bone, but we don't know what they smelled like, what kind of sounds they made, or how big they really looked standing in the grass under all those fossil fern trees. Even the sunlight must have been different, and the wind. What can bones tell you about a kind of wind that doesn't blow anymore?”

“How can it be?" she wondered. "I suppose I could understand it if men had simply forgotten unicorns (...) But not to see them at all, to look at them and see something else — what do they look to one another, then? What do trees look like to them, or houses, or real horses, or their own children?”

“I know exactly how you feel," Schmendrick said eagerly. The unicorn looked at him out of dark, endless eyes, and he smiled nervously and looked at his hands. "It's a rare man who is taken for what he truly is," he said. "There is much misjudgment in the world. Now I knew you for a unicorn when I first saw you, and I know that I am your friend. Yet you take me for a clown, or a clod, or a betrayer, and so must I be if you see me so. The magic on you is only magic and will vanish as soon as you are free, but the enchantment of error that you put on me I must wear forever in your eyes. We are not always what we seem, and hardly ever what we dream. Still I have read, or heard it sung, that unicorns when time was young, could tell the difference 'twixt the two - the false shining and the true, the lips' laugh and the heart's rue.”
