Plato Apology 18

[18] Hence, just as you would, of course, if I were really a foreigner, pardon me if I spoke in that dialect and that manner 18a in which I had been brought up, so now I make this request of you, a fair one, as it seems to me, that you disregard the manner of my speech—for perhaps it might be worse and perhaps better—and observe and pay attention merely to this, whether what I say is just or not; for that is the virtue of a judge, and an orator’s virtue is to speak the truth.
  First then it is right for me to defend myself against the first false accusations brought against me, and the first accusers, and then against the later accusations and the later accusers. 18b For many accusers have risen up against me before you, who have been speaking for a long time, many years already, and saying nothing true; and I fear them more than Anytus and the rest, though these also are dangerous; but those others are more dangerous, gentlemen, who gained your belief, since they got hold of most of you in childhood, and accused me without any truth, saying, There is a certain Socrates, a wise man, a ponderer over the things in the air and one who has investigated the things beneath the earth and who makes the weaker argument the stronger. These, men of Athens , 18c who have spread abroad this report, are my dangerous enemies. For those who hear them think that men who investigate these matters do not even believe in gods. Besides, these accusers are many and have been making their accusations already for a long time, and moreover they spoke to you at an age at which you would believe them most readily (some of you in youth, most of you in childhood), and the case they prosecuted went utterly by default, since nobody appeared in defence. But the most unreasonable thing of all is this, that it is not even possible 18d to know and speak their names, except when one of them happens to be a writer of comedies. And all those who persuaded you by means of envy and slander—and some also persuaded others because they had been themselves persuaded—all these are most difficult to cope with; for it is not even possible to call any of them up here and cross-question him, but I am compelled in making my defence to fight, as it were, absolutely with shadows and to cross-question when nobody answers. Be kind enough, then, to bear in mind, as I say, that there are two classes 18e of my accusers—one those who have just brought their accusation, the other those who, as I was just saying, brought it long ago, and consider that I must defend myself first against the latter; for you heard them making their charges first and with much greater force than these who made them later.
