general smiles. “You have forgotten all the lessons of history,” he says, “and all that nature of man which you described. Some conflicts are too fundamental to be resolved by negotiation; and during the prolonged negotiations (if history may be our guide) subversion would go on. A world order will come not by a gentlemen’s agreement, but through so decisive a victory by one of the great powers that it will be able to dictate and enforce international law, as Rome did from Augustus to Aurelius. Such interludes of widespread peace are unnatural and exceptional; they will soon be ended by changes in the distribution of military power. You have told us that man is a competitive animal, that his states must be like himself, and that natural selection now operates on an international plane. States will unite in basic co-operation only when they are in common attacked from without. Perhaps we are now restlessly moving toward that higher plateau of competition; we may make contact with ambitious species on other planets or stars; soon thereafter there will be interplanetary war. Then, and only then, will we of this earth be one.”
