So with that other story--How young Cyrus, giving out that his grandfather had made him general of the Persians, summoned them all, each man with a sickle in his hand, into a prairie full of thorns, and bade them clear it in one day; and how when they, like loyal men, had finished, he bade them bathe, and next day he took them into a great meadow and feasted them with corn and wine, and all that his father's farm would yield, and asked them which day they liked best; and, when they answered as was to be expected, how he opened his parable and told them, "Choose, then, to work for the Persians like slaves, or to be free with me." Such a tale sounds to me true. It has the very savour of the parables of the Old Testament; as have, surely, the dreams of the old Sultan, with which the tale begins. Do they not put us in mind of the dreams of Nebuchadnezzar, in the Book of Daniel? Such stories are actually so beautiful that they are very likely to be true. Understand me, I only say likely; the ditch-water view of history is not all wrong. Its advocates are right in saying great historic changes are not produced simply by one great person, by one remarkable event. They have been preparing, perhaps for centuries. They are the result of numberless forces, acting according to laws, which might have been foreseen, and will be foreseen, when the science of History is more perfectly understood. For instance, Cyrus could not have conquered the Median Empire at a single blow, if first that empire had not been utterly rotten; and next, if he and his handful of Persians had not been tempered and sharpened, by long hardihood, to the finest cutting edge. Yes, there were all the materials for the catastrophe--the cannon, the powder, the shot. But to say that the Persians must have conquered the Medes, even if Cyrus had never lived, is to say, as too many philosophers seem to me to say, that, given cannon, powder, and shot, it will fire itself off some day if we only leave it alone long enough. It may be so. But our usual experience of Nature and Fact is, that spontaneous combustion is a rare and exceptional phenomenon; that if a cannon is to be fired, someone must arise and pull the trigger. And I believe that in Society and Politics, when a great event is ready to be done, someone must come and do it--do it, perhaps, half unwittingly, by some single rash act--like that first fatal shot fired by an electric spark. But to return to Cyrus and his Persians.
