Especially intolerable to the more sensitive conscience of to-day is the assumption that nations may at will suspend or abrogate the ordinary moral code. For, as Lord Morley truly says, “To declare war is to suspend not merely _habeas corpus_ but the Ten Commandments, and some other good commandments besides.”[782] That is to say, war is a suspension of a great part of those rules of morality which, slowly and painfully formulated by the growing moral consciousness of man, have become the guide and standard of ordinary conduct. In war the conscience of the commander is inhibited. “The commander who lost a battle through the activity of his moral nature,” once cynically declared United States Senator Ingalls, “would be the derision and jest of history.” And that is so. The world has not yet ceased to deride those Jews who lost their city to the Romans because their consciences forsooth would not let them fight on the Sabbath day. War cannot be conducted by the rules of ordinary morality. With a great part of the ordinary moral code suspended, there is substituted for it a war code every maxim of which reveals its archaic, vestigial character, stamps it as a survival from an early savage stage of human development, as a legacy from a long-past age of the historical evolution when morality was as yet only an intratribal thing, that is, when men felt that they owed duties only to members of their own tribe or social group.[783] [Sidenote: Unfavorable reaction of the ethics of war upon the ethics of peace] In many ways, some obvious and others subtle and hidden, war works “moral damage” to society, but we here confine ourselves to emphasizing merely the moral loss and hurt resulting from the reaction of its low archaic code upon the more advanced peace code. For, as Professor J. Neville Figgis justly observes, “It is impossible to remove the very notion of morality from international affairs without in the long run undermining it in private life.”[784] What is regarded as right and proper in war will come to be regarded as right and proper in peace. That is to say, the maintenance of a double standard in morals is just as impossible as the maintenance of a double standard in money. By a sort of Gresham’s Law the lower standard will drive out the higher or drag it down to its own low level.
