III. History is silent as to the part taken by Aristides in the impeachment of Miltiades, but there is no reason to believe that he opposed the measure of the Alcmaeonid party with which he acted, and which seems to have obtained the ascendency after the death of Miltiades. In the year following the battle of Marathon, we find Aristides in the eminent dignity of archon. In this office he became generally known by the title of the Just. His influence, his official rank, the power of the party that supported him, soon rendered him the principal authority of Athens. The courts of the judges were deserted, every litigant repaired to his arbitration--his administration of power obtained him almost the monopoly of it. Still, however, he was vigorously opposed by Themistocles and the popular faction led by that aspiring rival. By degrees; various reasons, the chief of which was his own high position, concurred to diminish the authority of Aristides; even among his own partisans he lost ground, partly by the jealousy of the magistrates, whose authority he had superseded--and partly, doubtless, from a maxim more dangerous to a leader than any he can adopt, viz., impartiality between friends and foes in the appointment to offices. Aristides regarded, not the political opinions, but the abstract character or talents, of the candidates. With Themistocles, on the contrary, it was a favourite saying, "The gods forbid that I should be in power, and my friends no partakers of my success." The tendency of the first policy is to discontent friends, while it rarely, if ever, conciliates foes; neither is it so elevated as it may appear to the superficial; for if we contend for the superiority of one set of principles over another, we weaken the public virtue when we give equal rewards to the principles we condemn as to the principles we approve. We make it appear as if the contest had been but a war of names, and we disregard the harmony which ought imperishably to exist between the opinions which the state should approve and the honours which the state can confer. He who is impartial as to persons must submit to seem lukewarm as to principles. Thus the more towering and eminent the seeming power of Aristides, the more really hollow and insecure were its foundations. To his own party it was unproductive-- to the multitude it appeared unconstitutional. The extraordinary honours he had acquired--his monopoly of the magistrature--his anti-popular opinions, could not but be regarded with fear by a people so jealous of their liberties. He seemed to their apprehensions to be approaching gradually to the sovereignty of the state--not, indeed, by guards and military force, but the more dangerous encroachments of civil authority. The moment for the attack arrived. Themistocles could count at last upon the chances of a critical experiment, and Aristides was subjected to the ordeal of the ostracism.
