An intelligent Theban philosopher who discusses deeply with Socrates on the argument for the immortality of the soul. He is influenced by Pythagorean doctrines. At the critical moment of the event, he triggers a philosophical crisis by claiming that the soul could merely be an 'harmony' between the elements of the body, and therefore, with the destruction of the body, the soul (the harmony) would also be broken.
He came to Athens from Thebes and became one of Philolaus' students, having pondered significantly over sophists and philosophical arguments.
No specific features are given in the text, but he is presented as a vigorous and intellectual person belonging to the youth/young-adult generation.
