A Philosopher Warned

Κομπάζεις φιλοσοφίαν ἐχθρὰν τῆς ὄντως σοφίας, καὶ αὐτὸ ἀρνούμενος τὸ τοῦ πράγματος ὄνομα. Οὐδὲν γὰρ ἕτερόν ἐστι φιλοσοφία, ἤ τὸ πάντως φιλεῖν τὴν σοφίαν. Εἰ οὖν ὄντως ἐραστὴς εἶναι βούλει σοφίας, τὴν ὄντως ἀγάπα σοφίαν, οὐ τὸν λόγον μόνον, ἀλλὰ καὶ τὸν βίον συμνύνουσαν, καὶ τὴν ἀληθῆ θρησκείαν παιδεύουσαν. Ἥν γὰρ αὐτὸς ἐπαγγέλλῃ, καὶ νῦν ὀφλισκάνει γέλωτα, θεότητας καλοῦσα τὰς πηγὰς τῆς αἰσχρότητος, καὶ ἐν τῳ μέλλοντι τιμωρίαν ὠδίνει, ὅπου σοι τοὺς Κωκυτοὺς καὶ Πυριφλεγέθοντας ὁ Πλάτων ἠπείλησεν. Ἅγιος Ἰσίδωρος Του Πηλουσιώτου, Βιβλιον Πρῶτον, Ἐπιστολή ϟϚ' Μαξιμῳ Φιλοσοφῳ Ἐλληνι Source:  Migne PG 78. 248d-249a

The philosophy of which you boast is an enemy of true wisdom and denies itself the name of the deed. For philosophy is nothing but to love wisdom. If, then, you really wish to be a lover of wisdom, love the real wisdom, which is not only a word but even an adornment of life, and a preparation for the true religion. For what you now proclaim, even incurring laughter when it names the founts of shame divine, births punishment in the future, where Cocytus and Pyriphelgethon will await you, as Plato warned. 1 Saint Isidore of Pelusium, Book 1, Letter 96, to Maximus the Philosopher   1 1 Phadeo. 113d
