There is much to be said for it. In no other way could civilization have been spread so fast; by no other method could the world have become so rich in a few years. There was much to be said, also, for piracy. It diffused, manners, customs, and wealth; it made peoples acquainted with one another; it made a flat world round and laid the foundations of modern commerce. In the modern case all difficulty begins when the peoples to whom the less profitable tasks have been allotted become intelligently dissatisfied and resolve to change their status, as the American colonists did, as the Japanese did, as now all lusty nations are doing, last of all the Chinese. Modern trade evolved from piracy. There was a time when all transfer of goods between nations was by joyous might. It is pleasant to believe that the cause of the decline of piracy was a rise in the moral sense of mankind. It is more likely to have been the other way—that as piracy declined for rational reasons rules to govern commercial conduct became necessary. To enforce the rules became everyone’s duty. To break them was punishable. From this would germinate a moral sense. Piracy was bound to fail. On a large scale, continuous and competitive, it simply was not feasible. Competition ruined it. There was a marginal time in which one was either pirate or trader, agreeably to circumstance. The early Greek in his dangerous ship never knew which he was; nor did anyone else. He took when the taking was good; when it was not, he bartered. The Romans finally abolished piracy in the Mediterranean, but on the high seas it was the great romantic enterprize down to a very recent time. Some of its heroes are venerated as daring navigators, pathbreakers of empire. It takes some effort to remember that trees are still standing that were already old when the world was a place where finding was keeping. If what you found was in the possession of savages or heathens, you exchanged for it the hope of civilization, maybe a few glass beads. Toward the end, this wonderful business began to be hedged about with restrictions. You had to be careful not to take anything forcibly from people who had treaties of amity with your own country, for if you did they made trouble for you at home, diplomatically, and you might even be hanged at the end of an otherwise glorious voyage. But if you swindled them in trade, that was all right. Naturally, the first theory of trade was to give the least and get the most. There was else no point to it. The significance of trade has fundamentally changed in our time. What was a private adventure has become a national necessity, vital to the existing form of the principal industrial states of the world. And yet that first rude theory of it, representing the step from piracy to commerce, universally survives. This, at last, is the crucial fact.
