Plutarch, Fr. 203, recorded in Themistios’ On the Soul (From Stobaeus, iii.13. 68)

“Others will decide whether Diogenes spoke rightly about Plato “What good is a man who has practiced philosophy for a long time and pissed off no one? Perhaps it is right that the philosopher’s speech has a sweetness that wounds like honey.”

Θεμιστίου περὶ ψυχῆς·

Εἰ μὲν οὖν ὀρθῶς ἐπὶ Πλάτωνος εἶπε Διογένης, “τί δαὶ ὄφελος ἡμῖν ἀνδρὸς ὃς πολὺν ἤδη χρόνον φιλοσοφῶν οὐδένα λελύπηκεν;” ἕτεροι κρινοῦσιν. ἴσως γὰρ ὡς τὸ μέλι δεῖ καὶ τὸν λόγον τοῦ φιλοσόφου τὸ γλυκὺ δηκτικὸν ἔχειν τῶν ἡλκωμένων.

Diogenes Laertius, 10.8

“[Epicurus] used to call Nausiphanes an illiterate jellyfish, a cheat and a whore. He used to refer to Plato’s followers as the Dionysus-flatters; he called Aristotle a waste who, after he spent his interitance, fought as a mercenary and sold drugs. He maligned Protagoras as a bellboy, and called Protagoras Democritus’ secretary and a teacher from the sticks. He called Heraclitus mudman, Democritus  Lerocritus [nonsense lord].

Antidorus he called Sannidôros [servile-gifter]. He named the Cynics “Greece’s enemies”; he called the dialecticians Destructionists and, according to him, Pyrrho was unlearned and unteachable.”

πλεύμονά τε αὐτὸν ἐκάλει καὶ ἀγράμματον καὶ ἀπατεῶνα καὶ πόρνην: τούς τε περὶ Πλάτωνα Διονυσοκόλακας καὶ αὐτὸν Πλάτωνα χρυσοῦν, καὶ Ἀριστοτέλη ἄσωτον, <ὃν> καταφαγόντα τὴν πατρῴαν οὐσίαν στρατεύεσθαι καὶ φαρμακοπωλεῖν: φορμοφόρον τε Πρωταγόραν καὶ γραφέα Δημοκρίτου καὶ ἐν κώμαις γράμματα διδάσκειν: Ἡράκλειτόν τε κυκητὴν καὶ Δημόκριτον Ληρόκριτον καὶ Ἀντίδωρον Σαννίδωρον: τούς τε Κυνικοὺς ἐχθροὺς τῆς Ἑλλάδος: καὶ τοὺς διαλεκτικοὺς πολυφθόρους, Πύρρωνα δ᾽ ἀμαθῆ καὶ ἀπαίδευτον.
