A man must be far gone in Utopian speculations who can seriously doubt that, if these States should either be wholly disunited, or only united in partial confederacies, the subdivisions into which they might be thrown would have frequent and violent contests with each other. To presume a want of motives for such contests as an argument against their existence, would be to forget that men are ambitious, vindictive, and rapacious. To look for a continuation of harmony between a number of independent, unconnected sovereignties in the same neighborhood, would be to disregard the uniform course of human events, and to set at defiance the accumulated experience of ages. The causes of hostility among nations are innumerable. There are some which have a general and almost constant operation upon the collective bodies of society. Of this description are the love of power or the desire of pre-eminence and dominion--the jealousy of power, or the desire of equality and safety. There are others which have a more circumscribed though an equally operative influence within their spheres. Such are the rivalships and competitions of commerce between commercial nations. And there are others, not less numerous than either of the former, which take their origin entirely in private passions; in the attachments, enmities, interests, hopes, and fears of leading individuals in the communities of which they are members. Men of this class, whether the favorites of a king or of a people, have in too many instances abused the confidence they possessed; and assuming the pretext of some public motive, have not scrupled to sacrifice the national tranquillity to personal advantage or personal gratification. The celebrated Pericles, in compliance with the resentment of a prostitute,(1) at the expense of much of the blood and treasure of his countrymen, attacked, vanquished, and destroyed the city of the SAMMIANS. The same man, stimulated by private pique against the MEGARENSIANS,(2) another nation of Greece, or to avoid a prosecution with which he was threatened as an accomplice of a supposed theft of the statuary Phidias,(3) or to get rid of the accusations prepared to be brought against him for dissipating the funds of the state in the purchase of popularity,(4) or from a combination of all these causes, was the primitive author of that famous and fatal war, distinguished in the Grecian annals by the name of the PELOPONNESIAN war; which, after various vicissitudes, intermissions, and renewals, terminated in the ruin of the Athenian commonwealth.
