The dream of a time when the nations shall war no more is a pleasant dream, and an ancient. Countless generations have indulged it, and to countless others, doubtless, it will prove a solace and a benefaction. Yet one may be permitted to doubt if its ultimate realization is to be accomplished by diligent and general application to the task of learning war, as so many worthy folk believe. That every notable advance in the art of destroying human life should be “hailed” by these good people as a step in the direction of universal peace must be accounted a phenomenon entirely creditable to the hearts, if not to the heads, of those in whom it is manifest. It shows in them a constitution of mind opposed to bloodshed, for their belief having nothing to do with the facts—being, indeed, inconsistent with them—is obviously an inspiration of the will. “War,” these excellent persons reason, “will at last become so dreadful that men will no longer engage in it”—happily unconscious of the fact that men’s sense of their power to make it dreadful is precisely the thing which most encourages them to wage it. Another popular promise of peace is seen in the enormous cost of modern armaments and military methods. The shot and cartridge of a heavy gun of to-day cost hundreds of dollars, the gun itself tens of thousands. It is at an expense of thousands that a torpedo is discharged, which may or may not wreck a ship worth millions. To secure its safety from the machinations of its wicked neighbors while itself engaged in the arts of peace, a nation of to-day must have an immense sum of money invested in military plant alone. It is not of the nature of man to impoverish himself by investments from which he hopes for no return except security in the condition entailed by the outlay. Men do not construct expensive machinery, taxing themselves poor to keep it in working order, without ultimately setting it going. The more of its income a nation has to spend in preparation for war, the more certainly it will go to war. Its means of defense are means of aggression, and the stronger it feels itself to strike for its altars and its fires, the more spirited becomes its desire to go across the border to upset the altars and extinguish the fires of its neighbors. But the notion that improved weapons give modern armies and navies an increased killing ability—that the warfare of the future will be a bloodier business than that which we have the happiness to know—is an error which the observant lover of peace is denied the satisfaction of entertaining. Compare, for example, a naval engagement of to-day with Salamis, Lepanto or Trafalgar. Compare the famous duel between the _Monitor_ and the _Merrimac_ with almost any encounter between the old wooden line-of-battle ships, continued, as was the reprehensible custom, until one or both, with hundreds of dead and wounded, incarnadined the seas by going to the bottom.
