Lucian, On the Ignorant Book-Collector 26
“Once a dog has learned to chew leather it can’t stop. Another way is easier: not buying any more books. You are sufficiently educated, you have enough wisdom. You have all of antiquity nearly at the top of your lips.
You know all of history, every art of argumentation including their strengths and weaknesses and how to use Attic words. Your abundance of books has given you a special kind of wisdom and placed you at the peak of learning. Nothing stops me from messing with you since you enjoy being thoroughly deceived.”
οὐδὲ γὰρ κύων ἅπαξ παύσαιτ᾿ ἂν σκυτοτραγεῖν μαθοῦσα. τὸ δ᾿ ἕτερον ῥᾴδιον, τὸ μηκέτι ὠνεῖσθαι βιβλία. ἱκανῶς πεπαίδευσαι, ἅλις σοι τῆς σοφίας. μόνον οὐκ ἐπ᾿ ἄκρου τοῦ χείλους ἔχεις τὰ παλαιὰ πάντα. πᾶσαν μὲν ἱστορίαν οἶσθα, πάσας δὲ λόγων τέχνας καὶ κάλλη αὐτῶν καὶ κακίας καὶ ὀνομάτων χρῆσιν τῶν Ἀττικῶν· πάνσοφόν τι χρῆμα καὶ ἄκρον ἐν παιδείᾳ γεγένησαι διὰ τὸ πλῆθος τῶν βιβλίων. κωλύει γὰρ οὐδὲν κἀμέ σοι ἐνδιατρίβειν, ἐπειδὴ χαίρεις ἐξαπατώμενος.
Favorinus, [According to Aulus Gellius]
“It is impossible for someone who has fifteen thousand cloaks not to want more.”
τὸν γὰρ μυρίων καὶ πεντακισχιλίων χλαμύδων δεόμενον οὐκ ἔστι μὴ πλειόνων δεῖσθαι·
