In early times, there were no friendly neighbouring nations: beyond the boundaries of every nation’s territory, lay the land of a deadly foe. This was the way of thinking, even of so highly cultured a people as the Greeks, who believed that a law of nature had made every outsider, every barbarian their inferior and their enemy.[7] Their treaties of peace, at the time of the Persian War, were frankly of the kind denounced by Kant, mere armistices concluded for the purpose of renewing their fighting strength. The ancient world is a world of perpetual war in which defeat meant annihilation. In the East no right was recognised in the enemy; and even in Greece and Rome the fate of the unarmed was death or slavery.[8] The barbaric or non-Grecian states had, according to Plato and Aristotle, no claim upon humanity, no rights in fact of any kind. Among the Romans things were little better. According to Mr. T. J. Lawrence—see his _Principles of International Law_, III., §§ 21, 22—they were worse. For Rome stood alone in the world: she was bound by ties of kinship to no other state. She was, in other words, free from a sense of obligation to other races. War, according to Roman ideas, was made by the gods, apart altogether from the quarrels of rulers or races. To disobey the sacred command, expressed in signs and auguries would have been to hold in disrespect the law and religion of the land. When, in the hour of victory, the Romans refrained from pressing their rights against the conquered—rights recognised by all Roman jurists—it was from no spirit of leniency, but in the pursuit of a prudent and far-sighted policy, aiming at the growth of Roman supremacy and the establishment of a world-embracing empire, shutting out all war as it blotted out natural boundaries, reducing all rights to the one right of imperial citizenship. There was no real _jus belli_, even here in the cradle of international law; the only limits to the fury of war were of a religious character. [7] Similarly we find that the original meaning of the Latin word “_hostis_” was “a stranger.” [8] In Aristotle we find the high-water mark of Greek thinking on this subject. “The object of military training,” says he, (_Politics_, Bk. IV. Ch. XIV., Welldon’s translation—in older editions Bk. VII.) “should be not to enslave persons who do not deserve slavery, but firstly to secure ourselves against becoming the slaves of others; secondly, to seek imperial power not with a view to a universal despotic authority, but for the benefit of the subjects whom we rule, and thirdly, to exercise despotic power over those who are deserving to be slaves. That the legislator should rather make it his object so to order his legislation upon military and other matters as to promote leisure and peace is a theory borne out by the facts of history.” ... (_loc. cit._ Ch. XV.). “War, as we have remarked several times, has its end in peace.”
