Of all the enemies to public liberty war is, perhaps, the most to be dreaded, because it comprises and develops the germ
12 of every other. War is the parent of armies; from these proceed debts and taxes; and armies, and debts, and taxes are the known instruments for bringing the many under the domination
13 of the few. In war, too, the discretionary power of the Executive is extended; its influence in dealing out offices, honors, and emoluments is multiplied; and all the means of seducing the minds, are added to those of subduing the force, of the people. The same malignant aspect in republicanism may be traced in the inequality of fortunes, and the opportunities of fraud, growing out of a state of war, and in the degeneracy of manners and of morals, engendered by both. No nation could preserve its freedom in the midst of continual warfare.
Those truths are well established. They are read in every page which records the progression from a less arbitrary to a more arbitrary government, or the transition from a popular government to an aristocracy or a monarchy.
