"Through all the centuries of the worship of the mindless, whatever stagnation humanity chose to endure, whatever brutality to practice-it was only by the grace of the men who perceived that wheat must have water in order to grow, that stones laid in a curve will form an arch, that two and two make four, that love is not served by torture and life is not fed by destruction-only by the grace of those men did the rest of them learn to experience moments when they caught the spark of being human."
