"None of us, neither the sophists, nor the poets, nor the orators, nor the artists, nor I, know what is the nature of the _true_, the _good_, or the _beautiful_. But there is this difference between us; that, though none of these people know anything, they all think they know something; whereas for my part, if I know nothing, I am at least in no doubt of my ignorance. So the superiority of wisdom, imputed to me by the oracle, is reduced merely to my being fully convinced that I am ignorant of what I do not know." Thus we find Socrates, the wisest of men in the judgment of the god, and the most learned of all the Athenians in the opinion of all Greece, speaking in praise of ignorance. Were he alive now, there is little reason to think that our modern scholars and artists would induce him to change his mind. No, gentlemen, that honest man would still persist in despising our vain sciences. He would lend no aid to swell the flood of books that flows from every quarter: he would leave to us, as he did to his disciples, only the example and memory of his virtues; that is the noblest method of instructing mankind. Socrates had begun at Athens, and the elder Cato proceeded at Rome, to inveigh against those seductive and subtle Greeks, who corrupted the virtue and destroyed the courage of their fellow-citizens: culture, however, prevailed. Rome was filled with philosophers and orators, military discipline was neglected, agriculture was held in contempt, men formed sects, and forgot their country. To the sacred names of liberty, disinterestedness and obedience to law, succeeded those of Epicurus, Zeno and Arcesilaus. It was even a saying among their own philosophers that since learned men appeared among them, honest men had been in eclipse. Before that time the Romans were satisfied with the practice of virtue; they were undone when they began to study it.
