In this video series we look at one of Plato's dialogues, situated after the trial of Socrates before his execution. The central question of this portion of the dialogue we will examine is what is the soul, and what is it supposed to explain? In order to get there, first we discuss what it means for someone to die. What is death? At what point do you die? Here we describe Socrates's view that death is not a harm, as normally people think death is. Instead, death is a benefit, especially for a philosopher, since death involves the liberation from the body. Now we look at a formal argument in favor of the immorality of the soul. We consider an objection by Simmias, that the soul is not immortal, but depends on the body to exist. He suggests that the soul is a harmony, which relies on its parts working together in order to exist.
