Man, in recognizedly human shape, has been for ages on this planet, and the extraordinary discoveries in Egypt and Mesopotamia now enable us to see in dim fashion the beginning of historic times six or seven thousand years ago. In the earlier ages of which history speaks there was practically no such thing as an international conscience. The armies of Babylon and Assyria, Egypt and Persia felt no sense of obligation to outsiders and conquered merely because they wished to conquer. In Greece a very imperfect recognition of international right grew up so far as Greek communities were concerned, but it never extended to barbarians. In the Roman Empire this feeling grew slightly, if only for the reason that so many nations were included within its bounds and were forced to live peaceably together. In the Middle Ages the common Christianity of Europe created a real bond. There was at least a great deal of talk about the duties of Christian nations to one another; and although the action along the lines of the talk was lamentably insufficient, still the talk itself represented the dawning recognition of the fact that each nation might owe something to other nations and that it was not right to base action purely on self-interest. There has undoubtedly been a wide expansion of this feeling during the last few centuries, and particularly during the last century. It now extends so as to include not only Christian nations but also those non-Christian nations which themselves treat with justice and fairness the men of different creed. We are still a lamentably long distance away from the goal toward which we are striving; but we have taken a few steps toward that goal. A hundred years ago the English-speaking peoples of Britain and America regarded one another as inveterate and predestined enemies, just as three centuries previously had been the case in Great Britain itself between those who dwelt in the northern half and those who dwelt in the southern half of the island. Now war is unthinkable between us. Moreover, there is a real advance in good-will, respect, and understanding between the United States and all the other nations of the earth. The advance is not steady and it is interrupted at times by acts of unwisdom, which are quite as apt to be committed by ourselves as by other peoples; but the advance has gone on. There is far greater sentiment than ever before against unwarranted aggressions by stronger powers against weak powers; there is far greater feeling against misconduct, whether in small or big powers; and far greater feeling against brutality in war.
