Pythagoras, fr. b (58D.4) 4.1.49 (Frag. 35 Wehrli)
“Generally, they believed that it was necessary to posit that there is no greater evil than anarchy, since a human being cannot naturally save themselves when no one is watching over them. This is what they used to say then about those who rule and those who are ruled.
They used to claim that those who rule must not only have knowledge but also a love of humanity and that those who are ruled must not only obey but they should love their rulers. And they also believed that people at every age should practice: children practice reading and writing and other kinds of knowledge; adolescents learn the customs and laws of the state; adults focus on the actions and politics of their communities.
They believed that the aged should spend their time exhorting people, framing rules and giving advice with all of the knowledge they have gained, not to act foolishly like babies, nor adolescents like children, nor adults like adolescents, nor should the elderly act like crazy people.”
καθόλου δὲ ᾤοντο δεῖν ὑπολαμβάνειν μηδὲν εἶναι μεῖζον κακὸν ἀναρχίας· οὐ γὰρ πεφυκέναι τὸν ἄνθρωπον διασῴζεσθαι μηδενὸς ἐπιστατοῦντος. περὶ δὲ ἀρχόντων καὶ ἀρχομένων οὕτως ἐφρόνουν, τοὺς μὲν γὰρ ἄρχοντας ἔφασκον οὐ μόνον ἐπιστήμονας ἀλλὰ καὶ φιλανθρώπους δεῖν εἶναι, καὶ τοὺς ἀρχομένους οὐ μόνον πειθηνίους ἀλλὰ καὶ φιλάρχοντας. ἐπιμελητέον δὲ πάσης ἡλικίας ἡγοῦντο, καὶ τοὺς μὲν παῖδας ἐν γράμμασι καὶ τοῖς ἄλλοις μαθήμασιν ἀσκεῖσθαι, τοὺς δὲ νεανίσκους τοῖς τῆς πόλεως ἔθεσί τε καὶ νόμοις γυμνάζεσθαι, τοὺς δὲ ἄνδρας ταῖς πράξεσί τε καὶ δημοσίαις λειτουργίαις προσέχειν. τοὺς δὲ πρεσβύτας ἐνθυμήσεσι καὶ κριτηρίοις καὶ συμβουλίαις δεῖν ἐναναστρέφεσθαι μετὰ πάσης ἐπιστήμης ὑπελάμβανον, ὅπως μήτε οἱ παῖδες νηπιάζοιεν, μήτε οἱ νεανίσκοι παιδαριεύοιντο, μήτε οἱ ἅνδρες νεανιεύοιντο, μήτε οἱ γέροντες παραφρονοῖεν.
