Plato, The Statesman 301c-d
“But when someone in charge acts against both laws and customs, and claims like some genius that whatever is best should be done even against the written law and this desire and ignorance is driven by imitation, shouldn’t that kind of leader be called a Tyrant?
So we can say that a tyrant comes to power–and a king, an oligarchy, an aristocracy, or democracy, because people are not happy with one perfect monarch and do not believe that there even could be someone worthy of that kind of power, that they would be willing and capable of ruling with virtue and knowledge, distributing what is righteous and just to everyone correctly but instead suspecting them to insult and kill and harm whomever of us they want all the time.
Then, we agree that if such a person did exist, we would be in awe of them and invite them to live with us and run our affairs blissfully in a solely correct form of government.”
ΞΕ. Τί δ᾿, ὅταν μήτε κατὰ νόμους μήτε κατὰ ἔθη πράττῃ τις εἷς ἄρχων, προσποιῆται δὲ ὥσπερ ὁ ἐπιστήμων ὡς ἄρα παρὰ τὰ γεγραμμένα τό γε βέλτιστον ποιητέον, ᾖ δέ τις ἐπιθυμία καὶ ἄγνοια τούτου τοῦ μιμήματος ἡγουμένη, μῶν οὐ τότε τὸν τοιοῦτον ἕκαστον τύραννον κλητέον;
ΣΩ. Τί μήν;
ΞΕ. Οὕτω δὴ τύραννός τε γέγονε, φαμέν, καὶ βασιλεὺς καὶ ὀλιγαρχία καὶ ἀριστοκρατία καὶ δημοκρατία, δυσχερανάντων τῶν ἀνθρώπων τὸν ἕνα ἐκεῖνον μόναρχον, καὶ ἀπιστησάντων μηδένα τῆς τοιαύτης ἀρχῆς ἄξιον ἂν γενέσθαι ποτέ, ὥστε ἐθέλειν καὶ δυνατὸν εἶναι μετὰ ἀρετῆς καὶ ἐπιστήμης ἄρχοντα τὰ δίκαια καὶ ὅσια διανέμειν ὀρθῶς πᾶσι, λωβᾶσθαι δὲ καὶ ἀποκτιννύναι καὶ κακοῦν ὃν ἂν βουληθῇ ἑκάστοτε ἡμῶν· ἐπεὶ γενόμενόν γ᾿ ἂν οἷον λέγομεν ἀγαπᾶσθαί τε ἂν καὶ οἰκεῖν διακυβερνῶντα εὐδαιμόνως ὀρθὴν ἀκριβῶς μόνον πολιτείαν
