Problem: One of Socrates' arguments is that no one can practice an art well who doesn't know right from wrong. At one stage, he argues, "And he who has learned the art of music is a musician? [Gorgias answers, yes]. And he who has learned medicine is a physician? And so too on the same principle, the man who has learned anything becomes in each case such as his knowledge makes him? [Gorgias replies, certainly]. Then according to this principle, he who has learned justice is just (459d/460c). Socrates is urging the principle that "to know the good is to do the good," that seeing the good is sufficient to make a man do the good. What are the implications of this argument for our understanding of free will? Does the fact of our knowing it's wrong to steal make us not steal?
