Care was taken to divest the ostracism of all painful consequence except what was inseparable from exile; and this is not one of the least proofs of the wisdom with which it was devised. Most certainly, it never deprived the public of candidates for political influence: and when we consider the small amount of individual evil which it inflicted,—evil too diminished, in the cases of Cimon and Aristides, by a reactionary sentiment which augmented their subsequent popularity after return,—two remarks will be quite sufficient to offer in the way of justification. First, it completely produced its intended effect; for the democracy grew up from infancy to manhood without a single attempt to overthrow it by force—a result, upon which no reflecting contemporary of Clisthenes could have ventured to calculate. Next, through such tranquil working of the democratical forms, a constitutional morality quite sufficiently complete was produced among the leading Athenians, to enable the people after a certain time to dispense with that exceptional security which the ostracism offered. To the nascent democracy, it was absolutely indispensable; to the growing yet militant democracy, it was salutary; but the full-grown democracy both could and did stand without it. The ostracism passed upon Hyperbolus, about ninety years after Clisthenes, was the last occasion of its employment. And even this can hardly be considered as a serious instance: it was a trick concerted between two distinguished Athenians (Nicias and Alcibiades), to turn to their own political account a process already coming to be antiquated. Nor would such a manœuvre have been possible, if the contemporary Athenian citizens had been penetrated with the same serious feeling of the value of ostracism as a safeguard of democracy, as had been once entertained by their fathers and grandfathers. Between Clisthenes and Hyperbolus, we hear of about ten different persons as having been banished by ostracism. First of all, Hipparchus of the deme Cholargus, the son of Charmus, a relative of the recently expelled Pisistratid despots; then Aristides, Themistocles, Cimon, and Thucydides son of Melesias, all of them renowned political leaders; also Alcibiades and Megacles (the paternal and maternal grandfathers of the distinguished Alcibiades), and Callias, belonging to another eminent family at Athens; lastly, Damon, the preceptor of Pericles in poetry and music, and eminent for his acquisitions in philosophy. In this last case comes out the vulgar side of humanity, aristocratical as well as democratical; for with both, the process of philosophy and the persons of philosophers are wont to be alike unpopular. Even Clisthenes himself is said to be ostracised under his own law, and Xanthippus; but both upon authority too weak to trust. Miltiades was not ostracised at all, but tried and punished for misconduct in his command.
We should hardly have said so much about this memorable and peculiar institution of Clisthenes, if the erroneous accusations against the Athenian democracy—of envy, injustice, and ill-treatment of their superior men, had not been greatly founded upon it, and if such criticisms had not passed from ancient times to modern with little examination. In monarchical governments, a pretender to the throne, numbering a certain amount of supporters, is, as a matter of course, excluded from the country. No man treats this as any extravagant injustice, yet it is the parallel of the ostracism, with a stronger case in favour of the latter, inasmuch as the change from one regal dynasty to another does not of necessity overthrow all the collateral institutions and securities of the country. Plutarch has affirmed that the ostracism arose from the envy and jealousy inherent in a democracy, and not from justifiable fears—an observation often repeated, yet not the less demonstrably untrue. Not merely because ostracism so worked as often to increase the influence of that political leader whose rival it removed, but still more, because, if the fact had been as Plutarch says, this institution would have continued as long as the democracy; whereas it finished with the banishment of Hyperbolus, at a period when the government was more decisively democratical than it had been in the time of Clisthenes.
