From Plutarch’s How a Man May Became Aware of his Progress in Virtue (vol. 1 of the Loeb Moralia)
Just as persons who are being initiated into the Mysteries throng together at the outset amid tumult and shouting, and jostle against one another, but when the holy rites are being performed and disclosed the people are immediately attentive in awe and silence, so too at the beginning of philosophy: about its portals also you will see great tumult and talking and boldness, as some boorishly and violently try to jostle their way towards the repute it bestows: but he who has succeeded in getting inside, and has seen a great light, as though a shrine were opened, adopts another bearing of silence and amazement, and “humble and orderly attends upon” reason as upon a god. To these the humorous remark of Menedemus may, as it seems, be nicely applied; for he said that the multitudes who came to Athens to school were, at the outset, wise; later they became lovers of wisdom, later still orators, and, as time went on, just ordinary persons, and the more they laid hold on reason the more they laid aside their self-opinion and conceit.
ὥσπερ γὰρ οἱ τελούμενοι κατ᾿ ἀρχὰς μὲν ἐν θορύβῳ καὶ βοῇ συνίασι πρὸς Eἀλλήλους ὠθούμενοι, δρωμένων δὲ καὶ δεικνυμένων τῶν ἱερῶν προσέχουσιν ἤδη μετὰ φόβου καὶ σιωπῆς, οὕτω καὶ φιλοσοφίας ἐν ἀρχῇ καὶ περὶ θύρας πολὺν θόρυβον ὄψει καὶ λαλιὰν καὶ θρασύτητα, ὠθουμένων πρὸς τὴν δόξαν ἐνίων ἀγροίκως τε καὶ βιαίως· ὁ δ᾿ ἐντὸς γενόμενος καὶ μέγα φῶς ἰδών, οἷον ἀνακτόρων ἀνοιγομένων, ἕτερον λαβὼν σχῆμα καὶ σιωπὴν καὶ θαμβος ὥσπερ θεῷ τῷ λόγῳ “ταπεινὸς συνέπεται καὶ κεκοσμημένος.” εἰς δὲ τούτους ἔοικε καὶ τὸ Μενεδήμῳ πεπαιγμένον καλῶς λέγεσθαι· καταπλεῖν γὰρ ἔφη τοὺς πολλοὺς ἐπὶ σχολὴν Ἀθήναζε, σοφοὺς τὸ πρῶτον, εἶτα γίγνεσθαι φιλοσόφους, εἶτα ῥήτορας, τοῦ χρόνου δὲ προϊόντος ἰδιώτας, ὅσῳ μᾶλλον ἅπτονται τοῦ λόγου, μᾶλλον τὸ οἴημα καὶ τὸν τῦφον κατατιθεμένους.
