The word agriculture was coined in the 15th-century, but the process of cultivating the land to grow food has been in existence for much longer. Early farmers developed crops and livestock mainly to feed their families and local people.
Professor Faber is a retired English professor. He is a self-described coward, whom Montag turns to when he fails to understand the content of the books he's collected. Montag pushes Faber into conspiring with him to create change, although Faber believes they're too late to have any real effect. Montag's actions inspire the professor, however. It is Faber's voice in Montag's ear (via a two-way radio) that allows Montag to cope with Captain Beatty. Faber also reads to Montag through the earpiece, thus allowing Montag to hear and unknowingly retain literature.
Faber College has one frat house so disreputable it will take anyone. It has a second one full of white, anglo-saxon, rich young men who are so sanctimonious no one can stand them except Dean Wormer. The dean enlists the help of the second frat to get the boys of Delta House off campus. The dean's plan comes into play just before the homecoming parade to end all parades for all time.
