In intelligent life, human or Martian, maybe there has always been a genuine division between those who honor… — Edgar Pangborn

Never, beautiful Earth, never even at the height of the human storms have I forgotten you, my planet Earth, your forests and your fields, your oceans, the serenity of your mountains; the meadows, the continuing rivers, the incorruptible promise of returning spring.

I admit almost every charge of the indictment. The only thing wrong with it is that it’s too partial, too trivial. You’ve spent your life hunting for counterfeit money in a pile of treasure. You looked for evil all your life, to prove your case—naturally you found it, and where it was absent you created it. Any fool can do that. I’ve looked for good in human nature and elsewhere, and found it, heaped up and flowing over. Anyone can do that too, though good may be a little harder to see, because it’s all around you, no further away than the nearest leaf, the nearest smile or pleasant word, no further away than every breath of air. You say there’s no truth in men. Do you know what truth is, any more than Pilate did? Human beings are in the early stages of trying to accept and understand empirical truth.

If you’re interested in ethics, you could do worse than think in terms of geological time.
