Quotations about   others

While then the worst man is he who displays vice both in his own affairs and in his dealings with his friends, the best man is not he who displays virtue in his own affairs merely, but he who displays virtue towards others; for this is the hard thing to do.

[κάκιστος μὲν οὖν ὁ καὶ πρὸς αὑτὸν καὶ πρὸς τοὺς φίλους χρώμενος τῇ μοχθηρίᾳ, ἄριστος δ᾽ οὐχ ὁ πρὸς αὑτὸν τῇ ἀρετῇ ἀλλὰ πρὸς ἕτερον: τοῦτο γὰρ ἔργον χαλεπόν.]
