Plato, Letters 318c

τὰ χρήματα ἀποπέμπεσθαι. ἡνίκα γὰρ Ἡρακλείδην ἐξέβαλες, οὔτε Συρακοσίοις δοκοῦν δικαίως οὔτʼ ἐμοί, διότι μετὰ Θεοδότου καὶ Εὐρυβίου συνεδεήθην σου μὴ ποιεῖν ταῦτα, ταύτην λαβὼν ὡς ἱκανὴν πρόφασιν, εἶπες ὅτι καὶ πάλαι σοι δῆλος εἴην σοῦ μὲν οὐδὲν φροντίζων, Δίωνος δὲ καὶ τῶν Δίωνος φίλων καὶ οἰκείων, καὶ ἐπειδὴ νῦν Θεοδότης καὶ Ἡρακλείδης ἐν διαβολαῖς εἶεν, οἰκεῖοι Δίωνος ὄντες, πᾶν

seeking for the dispatch of the money, as being in ignorance of the events then going on. For when you sought to expel Heracleides unjustly, as it seemed to the Syracusans as well as to myself—because I had joined with Theodotes and Eurybius in entreating you not to do so, you took this as an ample excuse, and asserted that it had long been plain to you that I paid no regard to you, but only to Dion and Dion’s friends and connections, and now that Theodotes and Heracleides, who were Dion’s connections, were the subjects of accusations, I was using every means to prevent their paying the just penalty.
