Montag awakens ill the next morning. Mildred tries to care for her husband but finds herself more involved in the "parlor wall" entertainment in the living room – large televisions filling the walls. Montag suggests that maybe he should take a break from being a fireman after what happened last night, and Mildred panics over the thought of losing the house and her parlor wall "family". Captain Beatty, Montag's fire chief, personally visits Montag to see how he is doing. Sensing his concerns, Beatty recounts the history of how books lost their value and how the firemen were adapted for their current role: over the course of several decades, people began to embrace new media (in this case, film and television), sports, and an ever-quickening pace of life. Books were ruthlessly abridged or degraded to accommodate short attention spans. At the same time, advances in technology resulted in nearly all buildings being made out of fireproof materials, and the traditional role of firemen in preventing fires was no longer necessary. The government instead turned the firemen into officers of society's peace of mind: instead of putting out fires they became responsible for starting them, specifically for the purpose of burning books, which were condemned as sources of confusing and depressing thoughts that only complicated people's lives. After an awkward encounter between Mildred and Montag over the book hidden under Montag's pillow, Beatty becomes suspicious and casually adds a passing threat as he leaves, telling Montag that if a fireman had a book, he would be asked to burn it within the next 24 hours. If he refused, the other firemen would come and burn it for him. The encounter leaves Montag shaken.
