XXII. When he was an old man, Karneades the academic, and Diogenes the stoic philosopher, came as ambassadors to Rome on the part of the Athenians, to beg that they might not be forced to pay a fine of five hundred talents which had been imposed upon them in consequence of an action at law, brought against the Athenians by the people of Oropus, before the people of Sikyon as judges, having been allowed to go against them by default. Such of the Roman youths as had any taste for literature frequented the society of these men, and took great interest in hearing their discussions. They were especially delighted with Karneades, a man of great and recognised ability, who obtained large and enthusiastic audiences at his lectures, and filled the whole city with his fame. Nothing was talked of except how a single Greek with wonderful powers of eloquence and persuasion had so bewitched the youth of Rome that they forsook all other pleasures, and plunged wildly into philosophic speculations. The greater part of the citizens were well pleased with this, and looked on with great satisfaction at their sons' study of Greek literature, and their intimacy with such celebrated men; but Cato, when the taste for philosophy first sprang up in Rome, was vexed at it, and feared that the young men might become more eager to gain distinction by fluent speaking than by warlike exploits. However, when the fame of the philosophers increased, and a distinguished man, Caius Acilius, at the general request, translated their first lectures to the Senate, Cato decided that the philosophers must at once be conducted with all due honours out of the city. He came to the Senate and made a speech, in which he blamed them for having allowed an embassy to remain so long at Rome without accomplishing its purpose, although nothing was easier than for it to gain its point. He called upon them therefore, to decide as soon as possible and come to a vote upon the matter about which this embassy was come, in order that these philosophers might return to their schools and instruct the young men of Greece, while those of Rome might, as before, give their attention to the laws and the magistrates.
