[5] See Hume’s account of the origin of government (_Treatise_, III., Part II., Sect. VIII.). There are, he says, American tribes “where men live in concord and amity among themselves without any established government; and never pay submission to any of their fellows, except in time of war, when their captain enjoys a shadow of authority, which he loses after their return from the field, and the establishment of peace with the neighbouring tribes. This authority, however, instructs them in the advantages of government, and teaches them to have recourse to it, when either by the pillage of war, by commerce, or by any fortuitous inventions, their riches and possessions have become so considerable as to make them forget, on every emergence, the interest they have in the preservation of peace and justice.... Camps are the true mothers of cities; and as war cannot be administered, by reason of the suddenness of every exigency, without some authority in a single person, the same kind of authority naturally takes place in that civil government, which succeeds the military.” Cf. Cowper: _The Winter Morning Walk_:— “. . . . . . . . . . . . . . and ere long, When man was multiplied and spread abroad In tribes and clans, and had begun to call These meadows and that range of hills his own, The tasted sweets of property begat Desire of more; . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . Thus wars began on earth. These fought for spoil, And those in self-defence. Savage at first The onset, and irregular. At length One eminent above the rest, for strength, For stratagem, or courage, or for all, Was chosen leader. Him they served in war, And him in peace for sake of warlike deeds Rev’renced no less. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . Thus kings were first invented.” [6] “Among uncivilised nations, there is but one profession honourable, that of arms. All the ingenuity and vigour of the human mind are exerted in acquiring military skill or address.” Cf. Robertson’s _History of Charles V._, (_Works_, 1813, vol. V.) Sect. I. vii. _War in Classical Times._
