How does Beatty try to bait Montag into a confrontation when Montag returns a book to him at the fire station?

This happens at the card game in the station. Beatty starts baiting Montag by quoting literary passages. His quotations are contradictory and often from the same author. He is trying to prove to Montag that literature is full of contradictions meant to imprison our minds. Beatty goes on about how books are "traitors". Although Guy wants to rise to his challenge, and perhaps bash his head in, he stays quiet.
