The Most Dreaded Enemy of Liberty by James Madison,
Of all the enemies to liberty war is, perhaps, the most to be dreaded, because it comprises and develops the germ 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 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 Constitution expressly and exclusively vests in the Legislature the power of declaring a state of war [and] the power of raising armies.
A delegation of such powers [to the president] would have struck, not only at the fabric of our Constitution, but at the foundation of all well organized and well checked governments.
The separation of the power of declaring war from that of conducting it, is wisely contrived to exclude the danger of its being declared for the sake of its being conducted.
James Madison was the fourth president of the United States. This is from "Letters and Other Writings of James Madison ".
