" There is pleasure in watching the sophistries of mankind, his decisions made and unmade like the swirl of a mill-race, causation sweeping him forward from act to act while his reason dances on the surface of action like a pattern of foam. Yes, and the accumulations of human reason, she thought, the proofs we all assent to, the truths established beyond shadow of doubt, these are like the stale crusts of foam that lie along the river-bank and look solid enough, till a cloudburst further up the valley sends down a force of water that breaks them up and sweeps them away. "
