I used to think that forgiveness was a one-time and final act -- in one moment the pain subsides, and I say "I forgive," and it is over. But I have found that another day hidden memories spring forward from deep recesses of the mind and soul, and I must forgive again ... an ongoing project of the human soul.
Without faith that it is possible to render reality understandable by means of our theoretical constructs, without faith in an inner harmony of the world, there could be no science. This faith is and always will be the basic motivation behind every creative scientific idea. All our endeavors, all the dramatic conflicts between old and new ideas are supported by the eternal desire for knowledge, the unshakeable faith in cosmic harmony which becomes stronger the more difficulties loom before us.
