“Extremes should be avoided by wise men and fools.”
…τὸ πόρσω δ’ ἐστὶ σοφοῖς ἄβατον
κἀσόφοις.
ΕΥΔΟΞΑ ΑΓΝΩΣΤΑ ΚΑΤΑΓΕΛΑΣΤΑ
“It is difficult for an enemy to deceive
But it is easy for a friend to fool a friend.”
᾿Εχθρὸν μὲν χαλεπὸν καὶ δυσμενεῖ ἐξαπατῆσαι,
Κύρνε· φίλον δὲ φίλωι ῥάιδιον ἐξαπατᾶν.
Fool me once?
Theognis of Megara, a man with words for all occasions.
