Then came the argument. I think he thoroughly enjoyed it, and all the more because he could see and watch its effect upon Terry. Briefly, his thesis was that there was no such thing, ultimately, as progress. We were here in the world, and we didn't know why we were here; and there wasn't a scrap of evidence to show that world-movements had any permanent direction. The world had been inhabited for millions of years, and it was merely parochial conceit to suppose that our own civilization was the highest that had ever been known. The Greeks had excelled us in many of the arts; why not some earlier civilization in chemistry or engineering or medical science? It was a fascinating speculation. Quite possibly all the great discoveries had been made and remade over and over again throughout the ages. Nor could it be optimistically assumed that each successive civilization touched a higher peak than its predecessor. It was far more likely that there had been vast cycles of civilizations--some of them with an upward trend, and others with a downward--and that these cycles, in turn, belonged to even vaster movements. It was all, he admitted, very hazy and speculative; but at any rate it gave little support to those worthy Victorians who thought that the laying of the Transatlantic cable represented another step towards the millennium. "Then," I said, when he momentarily paused, "we might all of us just as well do evil as good." He demurred to the use of the words "good" and "evil." There were no absolute standards; the world had fashions in such things just as it had in dress and manners. _Anything_ was fashionable sometime or somewhere or other--murder in wartime, for instance, or bigamy in Turkey.... "Then what _are_ we to do?" "Do what you like. That's all the advice I can give you. _I_ always do what _I_ like. I like making speeches, for instance, and getting my name in the papers, and making plenty of money. But tastes differ, of course. And to those who live uncomfortably in this world in the hope of having everything made up to them in the next, my advice is just the same--If you _prefer_ having _that_ sort of a life and _that_ sort of a belief, then have them by all means."
