Plutarch, Comparison of Aristides with Marcus Cato
Bernadotte Perrin, Ed.

2. Besides, at Marathon, and again at Plataea, Aristides was only one of ten generals, while Cato was elected one of two consuls out of many competitors, and one of two censors over the heads of seven of the foremost and most illustrious Romans, who stood for the office with him. Furthermore, Aristides was not the foremost man in any one of his victories, but Miltiades has the chief honour of Marathon, Themistocles of Salamis, and at Plataea, Herodotus¹ says it was Pausanias who won that fairest of all victories, [2] while even for second honours Aristides has such rivals as Sophanes, Ameinias, Callimachus, and Cynaegeirus, who displayed the greatest valour in those actions. Cato, on the other hand, was not only chief in the plans and actions of the Spanish war during his own consulate, but also at Thermopylae, when he was but a tribune in the army and another was consul, he got the glory of the victory, opening up great mountain passes for the Romans to rush through upon Antiochus, and swinging the war round into the king's rear, when he had eyes only for what was in front of him. [3] That victory was manifestly the work of Cato, and it not only drove Asia out of Hellas, but made it afterwards accessible to Scipio.

It is true that both were always victorious in war, but in politics Aristides got a fall, being driven into a minority and ostracised by Themistocles. Cato, on the contrary, though he had for his antagonists almost all the greatest and ablest men in Rome, and though he kept on wrestling with them up to his old age, never lost his footing. [4] He was involved in countless civil processes, both as plaintiff and defendant; as plaintiff, he often won his case, as defendant, he never lost it, thanks to that bulwark and efficacious weapon of his life, his eloquence. To this, more justly than to fortune and the guardian genius of the man, we may ascribe the fact that he was never visited with disgrace. That was a great tribute which was paid Aristotle the philosopher by Antipater, when he wrote concerning him, after his death, that in addition to all his other gifts, the man had also the gift of persuasion.
