Knowing How to Be Silent is as Important as Knowing When to Speak (Plutarch, On the Education of Children, 10-11)

“Ruling your tongue, then, remains of the subjects about which I have set out to speak. If anyone thinks that this is a small or foolish matter, than he has strayed very far from the truth. For silence at the right time is a skill and stronger than all speech. For this reason it seems to me that the ancients established the mystery rights as they did, that, in becoming accustomed to silence during them, we may translate that fear from the gods to the safekeeping of human secrets. For, in turn, no one who was silent ever felt remorse about it; but countless chattering men felt regret. The word unsaid, moreover, is easy to speak out; but a spoken word cannot be taken back. I have heard of ten thousand men who have suffered the greatest misfortunes thanks to a loose tongue…”

Τὸ τοίνυν τῆς γλώττης κρατεῖν (περὶ τούτου γάρ, ὧνπερ ὑπεθέμην, εἰπεῖν λοιπόν) εἴ τις μικρὸν καὶ φαῦλον ὑπείληφε, πλεῖστον διαμαρτάνει τῆς ἀληθείας. σοφὸν γὰρ εὔκαιρος σιγὴ καὶ παντὸς λόγου κρεῖττον. καὶ διὰ τοῦτό μοι δοκεῖ τὰς μυστηριώδεις τελετὰς οἱ παλαιοὶ κατέδειξαν, ἵν’ ἐν ταύταις σιωπᾶν ἐθισθέντες ἐπὶ τὴν τῶν ἀνθρωπίνων μυστηρίων πίστιν τὸν ἀπὸ τῶν θείων μεταφέρωμεν φόβον. καὶ γὰρ αὖ σιωπήσας μὲν οὐδεὶς μετενόησε, λαλήσαντες δὲ παμπληθεῖς. καὶ τὸ μὲν σιγηθὲν ἐξειπεῖν ῥᾴδιον, τὸ δὲ ῥηθὲν ἀναλαβεῖν ἀδύνατον. μυρίους δ’ ἔγωγ’ οἶδ’ ἀκούσας ταῖς μεγίσταις συμφοραῖς περιπεσόντας διὰ τὴν τῆς γλώττης ἀκρασίαν.

Today Plutarch might say that not sending an email or a tweet is often better than sending one. My mother used to say “if you can’t say something nice, don’t say something at all”. It is not difficult to imagine Plutarch’s reactions to our constant invitations to commentary in the modern world. I do not think he would want people to be silent about corruption and injustice–this is a ‘manual’ for the raising of children–but instead that they learn the value of well-applied and strategic speech.

Not that Plutarch is necessarily a master of this. He left us enough words that “timeliness” of speech seems to have been his universal condition.
