“But how can it be? … I suppose I could understand it if men had simply forgotten unicorns—or if they had changed so that they hated all unicorns now—but not to see them at all, to look at them and see something else? What do they look like to one another, then? … If men no longer know what they are looking at, there may well be unicorns in the world yet.”

~Peter S. Beagle in The Last Unicorn
