The injunction, "In time of Peace prepare for War," is of Heathen origin.[316] As a rule of international conduct, it is very questionable in a Christian age, being vindicated on two grounds only: first, by assuming that the Arbitrament of War is the proper tribunal for international controversies, and therefore the War System is to be maintained and strengthened, as the essential means of international justice; or, secondly, by assuming the rejected dogma of an Atheist philosopher, Hobbes, that War is the natural state of man. Whatever may be the infirmities of our passions, it is plain that the natural state of man, assuring the highest happiness, and to which he tends by an irresistible heavenly attraction, is Peace. This is true of communities and nations, as of individuals. The proper rule is, In time of Peace cultivate the arts of Peace. So doing, you will render the country truly strong and truly great; not by arousing the passions of War, not by nursing men to the business of blood, not by converting the land into a flaming arsenal, a magazine of gunpowder, or an "infernal machine," just ready to explode, but by dedicating its whole energies to productive and beneficent works.

Look into the life of that illustrious philosopher, John Locke, and you will find, that, in the journal of his tour through France, describing the arches of the amphitheatre at Nismes, he says, "In all those arches, to support the walls over the passage where you go round, there is a stone laid, about twenty inches or two feet square, and about six times the length of _my sword, which was near about a philosophical yard long_."[317] Who is not struck with the unseemly incongruity of the exhibition, as he sees the author of the "Essay concerning Human Understanding" travelling with a sword by his side? But here the philosopher only followed the barbarous custom of his time. Individuals then lived in the same relations towards each other which now characterize nations. The War System had not yet entirely retreated from Municipal Law and Custom, to find its last citadel and temple in the Law and Custom of Nations. Do not forget, that, at the present moment, our own country, the great author, among the nations, of a new Essay concerning Human Understanding, not only travels with a sword by the side, like John Locke, but lives encased in complete armor, burdensome to limbs and costly to treasury.
