Ὁ γὰρ μισότεκνος καὶ πατὴρ πονηρὸς οὐκ ἄν ποτε γένοιτο δημαγωγὸς χρηστός, οὐδὲ ὁ τὰ φίλτατα καὶ οἰκειότατα σώματα μὴ στέργων οὐδέποθ’ ὑμᾶς περὶ πολλοῦ ποιήσεται τοὺς ἀλλοτρίους, οὐδέ γε ὁ ἰδίᾳ πονηρὸς ἄν ποτε γένοιτο δημοσίᾳ χρηστός, οὐδ’ ὅστις ἐστὶν οἴκοι φαῦλος, οὐδέποτ’ ἦν ἐν Μακεδονίᾳ καλὸς κἀγαθός· οὐ γὰρ τὸν τρόπον, ἀλλὰ τὸν τόπον μετήλλαξεν.
(Aeschines, Or. 3.78)
For the man who hates his child and is a bad father could never become a safe guide to the people; the man who does not cherish the persons who are nearest and dearest to him, will never care much about you, who are not his kinsmen; the man who is wicked in his private relations would never be found trustworthy in public affairs; and the man who is base at home was never a good and honourable man in Macedonia, for by his journey he changed his position, not his disposition. (tr. Charles Darwin Adams)
