“But Tom," said the moon, "the swinging of your pendulums! Everyone's a pendulum swinging, to and fro, and always you're getting hit by someone else's swinging pendulum. You're minding your own business, but someone else'e pendulum is swinging around, and pow! you get it in the head.”

If only a miracle could stop the pendulum at an angle of sixty degrees, one would believe the truth was there.”

“Ah, art! Ah, life! The pendulum swinging back and forth, from complex to simple, again to complex. From romantic to realistic, back to romantic. ”
