The Federalist Papers · Federalist No. 6 · paragraph 9

But notwithstanding the concurring testimony of experience, in this particular, there are still to be found visionary or designing men, who stand ready to advocate the paradox of perpetual peace between the States, though dismembered and alienated from each other. The genius of republics (say they) is pacific; the spirit of commerce has a tendency to soften the manners of men, and to extinguish those inflammable humors which have so often kindled into wars. Commercial republics, like ours, will never be disposed to waste themselves in ruinous contentions with each other. They will be governed by mutual interest, and will cultivate a spirit of mutual amity and concord.
