Dante placed the great geniuses of the pagan world, such as Plato and Aristotle, in Limbo, the first circle of Hell. They were not punished or tortured. Instead, they lived in a magnificent citadel of reason located in an idyllic valley with a beautiful meadow at its center. The light of their inner genius cast an enchanting glow over their world. We refer to this pagan citadel of rationalism as Castalia, or Logopolis, or the City of the Higher Sun, or Hyperborea. Are you a natural-born Castalian, or does reason nauseate you?
