In Fahrenheit 451, how is burning books the government's solution to creating a utopian society?

In Fahrenheit 451, the government burns books as a means of creating a utopia and to understand the logic behind this practice, we need to look at Captain Beatty's speech from Part One of the novel. According to Beatty, technological innovation is one of the reasons for the introduction of book-burning. Television, radio and film, for example, put pressure on books to be shorter and more easily digested by the population:

"Classics cut to fit fifteen-minute radio shows, then cut again to fill a two-minute book column, winding up at last as a ten- or twelve-line dictionary resume."

In addition, as the population increased, there was a growing need to protect the sensitivities of minorities, as Beatty explains:

"Don't step on the toes of the dog-lovers, cat-lovers, doctors, merchants."

Most importantly, burning books is about getting rid of topics which may offend or upset people. By turning everything into "vanilla tapioca" and avoiding sensitive or thought-provoking topics, the government ensures that everybody is happy on the surface, at least.
