If minds are wholly dependent on brains and brains on biochemistry, and biochemistry (in the long run) on the meaningless flux of the atoms, I cannot understand how the thought of those minds should have any more significance than the sound of the wind in the trees.
C. S. LewisThere is something in natural affection which will lead it on to eternal love more easily than natural appetite could be led on. But there's also something in it which makes it easier to stop at the natural level and mistake it for the heavenly. Brass is mistaken for gold more easily than clay is. And if it finally refuses conversion its corruption will be worse than the corruption of what ye call the lower passions. It is a stronger angel, and therefor, when it falls, a fiercer devil.
C. S. LewisA man can eat his dinner without understanding exactly how food nourishes him. A man can accept what Christ has done without knowing how it works: indeed, he certainly would not know how it works until he has accepted it.
