Note 31 — Chapter XIII · PLATO
W. B. (William Bernard) Hillis translation
The intellect-soul ἀθάνατον ἀρχὴν θνητοῦ ζῴου is the creation of the δημιουργός; the other faculties of the soul, θυμός, ἐπιθυμία (and αἴσθησις therewith), ψυχῆς ὅσον θνητὸν (Tim. 61 C), are all added to the soul at the moment of its union with the body by the subordinate deities: Tim. 41 D–44 D; 69 A–70 D (c. 14, 15, 31). The same idea appears in Rp. x, 611 BC. τὸ ἀειγενὲς μέρος τῆς ψυχῆς is distinguished from the ζωογενές: Polit. 309 C.
