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.
Montag asks for help with Beatty that night, and Faber gives him a two-way radio he has created that will fit in Montagâs ear; that way the professor can hear what Beatty has to say and also prompt Montag. Montag decides to risk giving Beatty a substitute book, and Faber agrees to see his printer friend.
