Plato Apology 38

[38] For if I say that such conduct would be disobedience to the god and that therefore I cannot keep quiet, you will think I am jesting and will not believe me; 38a and if again I say that to talk every day about virtue and the other things about which you hear me talking and examining myself and others is the greatest good to man, and that the unexamined life is not worth living, you will believe me still less. This is as I say, gentlemen, but it is not easy to convince you. Besides, I am not accustomed to think that I deserve anything bad. If I had money, I would have proposed a fine, 38b as large as I could pay; for that would have done me no harm. But as it is—I have no money, unless you are willing to impose a fine which I could pay. I might perhaps pay a mina of silver. So I propose that penalty; but Plato here, men of Athens , and Crito and Critobulus, and Aristobulus tell me to propose a fine of thirty minas, saying that they are sureties for it. So I propose a fine of that amount, and these men, who are amply sufficient, will be my sureties. 3 38c
  It is no long time, men of Athens , which you gain, and for that those who wish to cast a slur upon the state will give you the name and blame of having killed Socrates, a wise man; for, you know, those who wish to revile you will say I am wise, even though I am not. Now if you had waited a little while, what you desire would have come to you of its own accord; for you see how old I am, how far advanced in life and how near death. I say this not to all of you, 38d but to those who voted for my death. And to them also I have something else to say. Perhaps you think, gentlemen, that I have been convicted through lack of such words as would have moved you to acquit me, if I had thought it right to do and say everything to gain an acquittal. Far from it. And yet it is through a lack that I have been convicted, not however a lack of words, but of impudence and shamelessness, and of willingness to say to you such things as you would have liked best to hear. You would have liked to hear me wailing and lamenting and doing and saying 38e many things which are, as I maintain, unworthy of me—such things as you are accustomed to hear from others. But I did not think at the time that I ought, on account of the danger I was in, to do anything unworthy of a free man, nor do I now repent of having made my defence as I did, but I much prefer to die after such a defence than to live after a defence of the other sort.
