“We may not appreciate the fact; but a fact nevertheless it remains: we are living in a Golden Age, the most gilded Golden Age of human history — not only of past history, but of future history. For, as Sir Charles Darwin and many others before him have pointed out, we are living like drunken sailors, like the irresponsible heirs of a millionaire uncle. At an ever accelerating rate we are now squandering the capital of metallic ores and fossil fuels accumulated in the earth’s crust during hundreds of millions of years. How long can this spending spree go on? Estimates vary. But all are agreed that within a few centuries or at most a few millennia, Man will have run through his capital and will be compelled to live, for the remaining nine thousand nine hundred and seventy or eighty centuries of his career as Homo sapiens, strictly on income. Sir Charles is of the opinion that Man will successfully make the transition from rich ores to poor ores and even sea water, from coal, oil, uranium and thorium to solar energy and alcohol derived from plants. About as much energy as is now available can be derived from the new sources — but with a far greater expense in man hours, a much larger capital investment in machinery. And the same holds true of the raw materials on which industrial civilization depends. By doing a great deal more work than they are doing now, men will contrive to extract the diluted dregs of the planet’s metallic wealth or will fabricate non-metallic substitutes for the elements they have completely used up. In such an event, some human beings will still live fairly well, but not in the style to which we, the squanderers of planetary capital, are accustomed.”

Context: To be hopeful in bad times is not just foolishly romantic. It is based on the fact that human history is a history not only of cruelty, but also of compassion, sacrifice, courage, kindness. What we choose to emphasize in this complex history will determine our lives. If we see only the worst, it destroys our capacity to do something. If we remember those times and places — and there are so many — where people have behaved magnificently, this gives us the energy to act, and at least the possibility of sending this spinning top of a world in a different direction. And if we do act, in however small a way, we don’t have to wait for some grand utopian future. The future is an infinite succession of presents, and to live now as we think human beings should live, in defiance of all that is bad around us, is itself a marvelous victory.

Context: In an age which no longer waits patiently through this life for the rewards of the next, it is a crushing spiritual blow to lose one's sense of participation in mankind's journey, and to see only a huge milling-around, a collective living-out of lives with no larger purpose than the days which each accumulates. When we estrange ourselves from history we do not enlarge, we diminish ourselves, even as individuals. We subtract from our lives one meaning which they do in fact possess, whether we recognize it or not. We cannot help living in history. We can only fail to be aware of it. If we are to meet, endure, and transcend the trials and defeats of the future — for trials and defeats there are certain to be — it can only be from a point of view which, seeing the future as part of the sweep of history, enables us to establish our place in that immense procession in which is incorporated whatever hope humankind may have.
