φαύλους ἡγοῦ κτἑ, ‘consider not those men weak who accept a defeat which is to their advantage, but rather those who win a victory to their own hurt.’ For μετά see note on § 5 μετὰ τοιούτων συμφορῶν; and for περιγίγνεσθαι see note on E. 36.
τοὺς μείζω περιβαλλομένους ὧν οἷοί τ᾽ εἰσι κατασχεῖν, ‘those who aim at greater things than they can attain.’ ὧν is for ἐκείνων ἅ by relative attraction, see note on E. 11 ἧς; the genitive is that of the thing compared after μείζω.
