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.
Phaedo
In order to alleviate Cebes' worry that the soul might perish at death, Socrates introduces his first argument for the immortality of the soul. This argument is often called the "Cyclical Argument". It supposes that the soul must be immortal since the living come from the dead. Socrates says: "Now if it be true that the living come from the dead, then our souls must exist in the other world, for if not, how could they have been born again?". He goes on to show, using examples of relationships, such as asleep-awake and hot-cold, that things that have opposites come to be from their opposite. One falls asleep after having been awake. And after being asleep, he awakens. Things that are hot can become cold and vice versa. Socrates then gets Cebes to conclude that the dead are generated from the living, through death, and that the living are generated from the dead, through birth. The souls of the dead must exist in some place for them to be able to return to life.
