Healing And Wisdom

Ἰατρικὴ μὲν κατὰ Δημόκριτον, σώματος νόσους ἀκέεται· σοφίη δὲ ψυχὴν παθέων ἀφαιρέεται. Ἐπεὶ οὖν ἀμφοτέρας μετείληφας , καὶ θατέρᾳ κέχρηται πρὸς ἑτέρους, πάθη σωμάτων ἰώμενος · τῇ ἑτέρασαυτὸν ἐξιάτρευσον, τὴν λείπουσαν ὑγείαν προσκτώμενος, ἧς ἄνευ οὔτε ἰατρὸς ἄριστος, οὔτε σοφός ἔσῃ τῷ πράγματι. Ἅγιος Ἰσίδωρος Του Πηλουσιώτου, Βιβλίον Πρῶτον, Ἐπιστολὴ ΥΛΖ' Ὀριβασιῳ Ἰατρῳ Source: Migne 78.424a

Saint Isidore of Pelusium, Book 1, Letter 437, To Oribasius the Physician
