After much effort, as names, definitions, sights, and other data of sense, are brought into contact and friction one with another, in the course of scrutiny and kindly testing by men who proceed by question and answer without ill will, with a sudden flash there shines forth understanding about every problem, and an intelligence whose efforts reach the furthest limits of human powers.
μόγις δὲ τριβόμενα πρὸς ἄλληλα αὐτῶν ἕκαστα, ὀνόματα καὶ λόγοι ὄψεις τε καὶ αἰσθήσεις, ἐν εὐμενέσιν ἐλέγχοις ἐλεγχόμενα καὶ ἄνευ φθόνων ἐρωτήσεσιν καὶ ἀποκρίσεσιν χρωμένων, ἐξέλαμψε φρόνησις περὶ ἕκαστον καὶ νοῦς, συντείνων ὅτι μάλιστ᾽ εἰς δύναμιν ἀνθρωπίνην.
