η41Ἡγεμονικόν
authoritative [part]
[Meaning] the mind. Or "the principal part of the soul, where the images and impulses are produced, and from where thought is transmitted; which [they say] is precisely located in the heart."
Ἡγεμονικόν· ὁ νοῦς. ἢ τὸ κυριώτατον τῆς ψυχῆς, ἐν ᾧ αἱ φαντασίαι καὶ αἱ ὁρμαὶ γίνονται, καὶ ὅθεν ὁ λόγος ἀναπέμπεται· ὅπερ εἶναι ἐν τῇ καρδίᾳ.
