και ἅμα ἐλευθέραν καὶ εὐδοξοτάτην πόλιν διὰ παντὸς νεμόμεθα και δύναται μάλιστα σωφροσύνη ἔμφρων τοῦτ᾿ εἶναι → Just remember, we're a people with a long-standing reputation for freedom, a people held in the highest honor. Slowness to act can be nothing more than a mark of clear-headed self-control (Spartan King Archidamus)
