On the rhetorical and philosophical nature of the eschatological myth of Plato's Gorgias

The Gorgias shows an intense debate on persuasion. One of the theses held by Socrates is that there are two forms of persuasion: one that produces mere belief -pi epsilon iota theta omega pi iota sigma tau epsilon upsilon tau iota kappa eta- and another one, substantially different, which teaches -pi epsilon iota theta omega delta iota delta alpha sigma kappa alpha lambda iota kappa eta. This article relates these two forms of persuasion to traditional rhetoric and philosophy respectively. Besides, it analyzes the conclusive myth of the Gorgias according to these two forms of persuasion; a myth in which Socrates deals with the fate of souls in the afterlife. The outcome is that the content of the final myth is consistent with the arguments given by Socrates during the previous conversation and that Plato, by using the myth, reflects on the limits of philosophical teaching.
