The answer begins by clearing up a confusion. In the representations of the Comic poets, and in the opinion of the multitude, he had been identified with the teachers of physical science and with the Sophists. But this was an error. For both of them he professes a respect in the open court, which contrasts with his manner of speaking about them in other places. (Compare for Anaxagoras, Phædo, Laws; for the Sophists, Meno, Republic, Tim., Theaet., Soph., etc.) But at the same time he shows that he is not one of them. Of natural philosophy he knows nothing; not that he despises such pursuits, but the fact is that he is ignorant of them, and never says a word about them. Nor is he paid for giving instruction—that is another mistaken notion:—he has nothing to teach. But he commends Evenus for teaching virtue at such a “moderate” rate as five minæ. Something of the “accustomed irony,” which may perhaps be expected to sleep in the ear of the multitude, is lurking here. He then goes on to explain the reason why he is in such an evil name. That had arisen out of a peculiar mission which he had taken upon himself. The enthusiastic Chaerephon (probably in anticipation of the answer which he received) had gone to Delphi and asked the oracle if there was any man wiser than Socrates; and the answer was, that there was no man wiser. What could be the meaning of this—that he who knew nothing, and knew that he knew nothing, should be declared by the oracle to be the wisest of men? Reflecting upon the answer, he determined to refute it by finding “a wiser;” and first he went to the politicians, and then to the poets, and then to the craftsmen, but always with the same result—he found that they knew nothing, or hardly anything more than himself; and that the little advantage which in some cases they possessed was more than counter-balanced by their conceit of knowledge. He knew nothing, and knew that he knew nothing: they knew little or nothing, and imagined that they knew all things. Thus he had passed his life as a sort of missionary in detecting the pretended wisdom of mankind; and this occupation had quite absorbed him and taken him away both from public and private affairs. Young men of the richer sort had made a pastime of the same pursuit, “which was not unamusing.” And hence bitter enmities had arisen; the professors of knowledge had revenged themselves by calling him a villainous corrupter of youth, and by repeating the commonplaces about atheism and materialism and sophistry, which are the stock-accusations against all philosophers when there is nothing else to be said of them.
