Remember that it is not he who gives abuse or blows who affronts, but the view we take of these things as insulting. When, therefore, any one provokes you, be assured that it is your own opinion which provokes you.
Μέμνησο ὅτι οὐχ ὁ λοιδορῶν ἢ τύπτων ὑβρίζει, ἀλλὰ τὸ δόγμα τὸ περὶ τούτων ὡς ὑβριζόντων. ὅταν οὖν ἐρεθίσῃ σέ τις, ἴσθι ὅτι ἡ σή σε ὑπόληψις ἠρέθισε.
