Gonzalez Lodge, Commentary on Plato: Gorgias

ἀγνοῶν γε: Plato frequently employs participial clauses as a kind of addendum to sentences which are either interrupted by the answer of the respondent or already complete in themselves.

οἷον: what sort of a thing.

11 f.

καθορᾶν ... ἀγνοεῖν: is epexegetical to τοιοῦτόν τι, and corresponds to συνισχόμενος . . . φοβούμενος and ἀγνοῶν in the comparison above.

12 f.

μὴ ὑγιοῦς σώματος: a harsh use of the comparative gen. equiv. to ἢ μὴ ὑγιεῖ σώματι. See Madv. Syn. § 90.

συνοικεῖν: divorces the human personality from the soul and body, by a union of which it exists. With καθορᾶν κτἑ., Plato thins especially of the νοῦς to which he opposes that part which, in its subserviency to the lusts and appetites, willingly withdraws from the control of reason.

σαθρᾷ: is used of injuries and defects of all kinds, whether of material things, as jars (493 e), or of the body (Dem. Ol. ii. 21 κἂν ῥῆγμα (fracture) κἂν στρέμμα (dislocation) κἂν ἄλλο τι τῶν ὑπαρχόντων σαθρὸν ᾖ). From this meaning comes its transferred use in application to the soul or the state. Notice that the unhealthy soul is designated as σαθρά from a physical point of view, ἄδικος in its dealings with its neighbors, and ἀνόσιος in its attitude towards the divine.
