Socrates (film)
His enemies, led by a young man named Meletus, accuse him in court, arguing that the philosopher preaches crazy doctrines to the youth, and does not believe in the gods, but demons. Socrates makes his "apology" (i.e., legal defense), but the citizens are against him; so Socrates is sentenced to death, and held in prison, awaiting execution. His disciples are desperate, and one of them, Crito, tries to help him by encouraging him to flee. Socrates rejects this idea, saying he must obey the rulers of the city. Socrates then resolves to die, and dies as soon as he is forced to drink hemlock.
Theaetetus (dialogue)
Since Protagoras is dead, Socrates puts himself in the sophist's shoes and tries to do him the favor of defending his idea (166a-168c). Socrates concedes that if Protagoras were still alive, he would have more to say in his own defense, and that they are now essentially mistreating "his orphan child." Putting words in the dead sophist's mouth, Socrates declares that Protagoras asserts with his maxim that all things are in motion and whatever seems to be the case, is the case for the perceiver, whether the individual or the state.
