Note 22 — Chapter XIII · PLATO

Phdr. 245 C–246 A. The soul is τὸ αὑτὸ κινοῦν, and indeed continually, ἀεικίνητον, it is τοῖς ἄλλοις ὅσα κινεῖται πηγὴ καὶ ἀρχὴ κινήσεως (the body only seems to move itself, but it is really the soul within which moves it—246 C). If the soul were to perish, πᾶς οὐρανὸς πᾶσά τε γένεσις would be at a standstill. The conception of the “soul” as the ἀεικίνητον was already well and long established in Plato’s time (see above, chap. xii, n. 150). In the form in which he introduces it here (as a proof of the imperishability of the soul) he may have modelled his conception on that of Alkmaion (Arist., An. 405a, 29): see Hirzel, Hermes, xi, 244. But Plato here and throughout Phdr. is speaking of the individual soul (ψυχή collective singular). So too in Lg. 894 E ff., 896 A ff. (λόγος of the soul: ἡ δυναμένη αὐτὴ αὑτὴν κινεῖν κίνησις. It is the αιτία and the issue of all movement in the world, the source of life; for life belongs to that which αὐτό αὑτὸ κινεῖ 895 C.) As distinguished from the ψυχὴ ἐνοικοῦσα ἐν ἅπασι τοῖς κινουμένοις we do not hear of the (double) World-Soul until 896 E. There is in fact κίνησις in plenty in the world besides that of the animated organisms.
