Plato Apology 35

[35] If then those of you who are supposed to be superior either in wisdom or in courage or in any other virtue whatsoever are to behave in such a way, it would be disgraceful. Why, I have often seen men who have some reputation behaving in the strangest manner, when they were on trial, as if they thought they were going to suffer something terrible if they were put to death, just as if they would be immortal if you did not kill them. It seems to me that they are a disgrace to the state and that any stranger might say that those of the Athenians who excel 35b in virtue, men whom they themselves honor with offices and other marks of esteem, are no better than women. Such acts, men of Athens , we who have any reputation at all ought not to commit, and if we commit them you ought not to allow it, but you should make it clear that you will be much more ready to condemn a man who puts before you such pitiable scenes and makes the city ridiculous than one who keeps quiet.
  But apart from the question of reputation, gentlemen, I think it is not right 35c to implore the judge or to get acquitted by begging; we ought to inform and convince him. For the judge is not here to grant favors in matters of justice, but to give judgement; and his oath binds him not to do favors according to his pleasure, but to judge according to the laws; therefore, we ought not to get you into the habit of breaking your oaths, nor ought you to fall into that habit; for neither of us would be acting piously. Do not, therefore, men of Athens , demand of me that I act before you in a way which I consider neither honorable nor right nor pious, 35d especially when impiety is the very thing for which Meletus here has brought me to trial. For it is plain that if by persuasion and supplication I forced you to break your oaths I should teach you to disbelieve in the existence of the gods and in making my defence should accuse myself of not believing in them. But that is far from the truth; for I do believe in them, men of Athens , more than any of my accusers, and I entrust my case to you and to God to decide it as shall be best for me and for you.
