A great man need not be virtuous, nor his opinions right, but he must have a firm mind, a distinctive luminous character.
George SantayanaNature in denying us perennial youth has at least invited us to become unselfish and noble.
George SantayanaEven the most inspired verse, which boasts not without a relative justification to be immortal, becomes in the course of ages a scarcely legible hieroglyphic; the language it was written in dies, a learned education and an imaginative effort are requisite to catch even a vestige of its original force. Nothing is so irrevocable as mind.
George Santayana
