Plato, Republic 6 488a7-89a2
Consider this how this could turn out on many ships or even just one: there is a captain of some size and strength beyond the rest of the men in the ship, but he is deaf and similarly limited at seeing, and he knows as much about sailing as these qualities might imply. So, the sailors are struggling with one another about steering the ship, because each one believes that he should be in charge, even though he has learned nothing of the craft nor can indicate who his teacher was nor when he had the time to learn. Some of them are even saying that it is not teachable, and that they are ready to cut down the man who says it can be taught.
They are always hanging all over the captain asking him and making a big deal of the fact that he should entrust the rudder to them. There are times when some of them do not persuade him, and some of them kill others or kick them off the ship, and once they have overcome the noble captain through a mandrake, or drugs, or something else and run the ship, using up its contents drinking, and partying, and sailing just as such sort of men might. In addition to this, they praise as a fit sailor, and call a captain and knowledgeable at shipcraft the man who is cunning at convincing or forcing the captain that they should be in charge. And they rebuke as useless anyone who is not like this.
Such men are unaware what a true helmsman is like, that he must be concerned about the time of year, the seasons, the sky, the stars, the wind and everything that is appropriate to the art, if he is going to be a leader of a ship in reality, how he might steer the ship even if some desire it or not, when they believe that it is not possible to obtain art or practice about how to do this, something like an art of ship-steering. When these types of conflicts are occurring on a ship, don’t you think the one who is a true helmsman would be called a star-gazer, a blabber, or useless to them by the sailors in the ships organized in this way?
νόησον γὰρ τοιουτονὶ γενόμενον εἴτε πολλῶν νεῶν πέρι εἴτε μιᾶς· ναύκληρον μεγέθει μὲν καὶ ῥώμῃ ὑπὲρ τοὺς ἐν τῇ νηὶ πάντας, ὑπόκωφον δὲ καὶ ὁρῶντα ὡσαύτως βραχύ τι καὶ γιγνώσκοντα περὶ ναυτικῶν ἕτερα τοιαῦτα, τοὺς δὲ ναύτας στασιάζοντας πρὸς ἀλλήλους περὶ τῆς κυβερνήσεως, ἕκαστον οἰόμενον δεῖν κυβερνᾶν, μήτε μαθόντα πώποτε τὴν τέχνην μέτε ἔχοντα ἀποδεῖξαι διδάσκαλον ἑαυτοῦ μηδὲ χρόνον ἐν ᾧ ἐμάνθανεν, πρὸς δὲ τούτοις φάσκοντας μηδὲ διδακτὸν εἶναι, ἀλλὰ καὶ τὸν λέγοντα ὡς διδακτὸν ἑτοίμους κατατέμνειν, αὐτοὺς δὲ αὐτῷ ἀεὶ τῷ ναυκλήρῳ περικεχύσθαι δεομένους καὶ πάντα ποιοῦντας ὅπως ἂν σφίσι τὸ πηδάλιον ἐπιτρέψῃ, ἐνίοτε δ’ ἂν μὴ πείθωσιν ἀλλὰ ἄλλοι μᾶλλον, τοὺς μὲν ἄλλους ἢ ἀποκτεινύντας ἢ ἐκβάλλοντας ἐκ τῆς νεώς, τὸν δὲ γενναῖον ναύκληρον μανδραγόρᾳ ἢ μέθῃ ἤ τινι ἄλλῳ συμποδίσαντας τῆς νεὼς ἄρχειν χρωμένους τοῖς ἐνοῦσι, καὶ πίνοντάς τε καὶ εὐωχουμένους πλεῖν ὡς τὸ εἰκὸς τοὺς τοιούτους, πρὸς δὲ τούτοις ἐπαινοῦντας ναυτικὸν μὲν καλοῦντας καὶ κυβερνητικὸν καὶ ἐπιστάμενον τὰ κατὰ ναῦν, ὃς ἂν συλλαμβάνειν δεινὸς ᾖ ὅπως ἄρξουσιν ἢ πείθοντες ἢ βιαζόμενοι τὸν ναύκληρον, τὸν δὲ μὴ τοιοῦτον ψέγοντας ὡς ἄχρηστον, τοῦ δὲ ἀληθινοῦ κυβερνήτου πέρι μηδ’ ἐπαΐοντες, ὅτι ἀνάγκη αὐτῷ τὴν ἐπιμέλειαν ποιεῖσθαι ἐνιαυτοῦ καὶ ὡρῶν καὶ οὐρανοῦ καὶ ἄστρων καὶ πνευμάτων καὶ πάντων τῶν τῇ τέχνῃ προσηκόντων, εἰ μέλλει τῷ ὄντι νεὼς ἀρχικὸς ἔσεσθαι, ὅπως δὲ κυβερνήσει ἐάντε τινες βούλωνται ἐάντε μή, μήτε τέχνην τούτου μήτε μελέτην οἰόμενοι δυνατὸν εἶναι λαβεῖν ἅμα καὶ τὴν κυβερνητικήν. τοιούτων δὴ περὶ τὰς ναῦς γιγνομένων τὸν ὡς ἀληθῶς κυβερνητικὸν οὐχ ἡγῇ ἂν τῷ ὄντι μετεωροσκόπον τε καὶ ἀδολέσχην καὶ ἄχρηστόν σφισι καλεῖσθαι ὑπὸ τῶν ἐν ταῖς οὕτω κατεσκευασμέναις ναυσὶ πλωτήρων;
