what is the strongest impetus for the discontent of the fahrenheit citizens

There are those people who remember another use for books and remember that the books were a good thing. They do not, as does Captain Beatty, have a "pat" explanation for the way in which books disappeared. Rather, they want to have the individuality that comes from associating oneself with books. Montag, as he delves into the books he steals, and as he realizes how much he misses Clarisse, notes that there is more to life than Mildred, her TV, and he seashell radio. Truly, all people who become discontent realize that the past with its books to be read represent a better life.
