Hamilton's answer to the democratic peace proposition, that most cherished stricture of american political science:

'But notwithstanding the concurring testimony of experience...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.

'Is it not (we may ask these projectors in politics) the true interest of all nations to cultivate the same benevolent and philosophic spirit? If this be their true interest, have they in fact pursued it? Has it not, on the contrary, invariably been found that momentary passions, and immediate interests, have a more active and imperious control over human conduct than general or remote considerations of policy, utility, or justice? Have republics in practice been less addicted to war than monarchies? Are not the former administered by men as well as the latter? Are there not aversions, predilections, rivalships, and desires of unjust acquisitions that affect nations as well as kings? Are there not popular assemblies frequently subject to the impulses of rage, resentment, jealousy, avarice, and of other irregular and violent propensities? Is it not well known that their determinations are often governed by a few individuals in whom they place confidence, and are, of course, liable to be tinctured by the passions and views of those individuals? Has commerce hitherto done any thing more than change the objects of war? Is it not the love of wealth as domineering and enterprising a passion as that of power or glory? Have there not been as many wars founded upon commercial motives since that has become the prevailing system of nations, as were before occasioned by the cupidity of territory or dominion? Has not the spirit of commerce, in many instances, administered new incentives to the appetite, both for the one and for the other? Let experience, the least fallible guide of human opinions, be appealed to for an answer to these inquiries.'
