Some one will say: Yes, Socrates, but cannot you hold your tongue, and then you may go into a foreign city, and no one will interfere with you? Now I have great difficulty in making you understand my answer to this. • For wherever he goes he must speak out.For if I tell you that to do as you say would be a disobedience to the God, and therefore that I cannot hold my tongue, you will not • believe that I am serious; and if I say again that daily to discourse about virtue, and of those other things about which you hear me examining myself and others, is the greatest good of man, and that the unexamined life is not worth living, you are still less likely to believe me. Yet I say what is true, although a thing of which it is hard for me to persuade you. Also, I have never been accustomed to think that I deserve to suffer any harm. Had I money I might have estimated the offence at what I was able to pay, and not have been much the worse. But I have none, and therefore I must ask you to proportion the fine to my means. Well, perhaps I could afford a mina, and therefore I propose that penalty: Plato, Crito, Critobulus, and Apollodorus, my friends here, bid me say thirty minae, and they will be the sureties. Let thirty minae be the penalty; for which sum they will be ample security to you.
