Socrates was charged with corrupting the youth of Athens with his teachings. The Court offered to free him if he would recant his teachings before the youth, but he chose the poison Hemlock instead because the truth was that important to him. Many think this event launched the discipline of Philosophy itself.
“And I swear to you, Athenians, by the dog I swear!, for I must tell you the truth, the result of my mission was just this: I found that the men most in repute were all but the most foolish; and that others less esteemed were really wiser and better. …..Men of Athens, I honor and love you; but I shall obey God rather than you, and while I have life and strength I shall never cease from the practice and teaching of philosophy, exhorting any one whom I meet and saying to him after my manner: You, my friend,, a citizen of the great and mighty and wise city of Athens,, are you not ashamed of heaping up the greatest amount of money and honor and reputation, and caring so little about wisdom and truth and the greatest improvement of the soul, which you never regard or heed at all? And if the person with whom I am arguing, says: Yes, but I do care; then I do not leave him or let him go at once; but I proceed to interrogate and examine and cross-examine him, and if I think that he has no virtue in him, but only says that he has, I reproach him with undervaluing the greater, and overvaluing the less. And I shall repeat the same words to every one whom I meet, young and old, citizen and alien, but especially to the citizens, inasmuch as they are my brethren. For know that this is the command necessity of God; and I believe that no greater good has ever happened in the state than my service to the God. For I do nothing but go about persuading you all, old and young alike, not to take thought for your persons or your properties, but first and chiefly to care about the greatest improvement of the soul. I tell you that virtue is not given by money, but that from virtue comes money and every other good of man, public as well as private. This is my teaching, and if this is the doctrine which corrupts the youth, I am a mischievous person. But if any one says that this is not my teaching, he is speaking an untruth. Wherefore, O men of Athens, I say to you, do as Anytus bids or not as Anytus bids, and either acquit me or not; but whichever you do, understand that I shall never alter my ways, not even if I have to die many times.”
