In Ray Bradbury's Fahrenheit 451, freedom is a theme that is explored and contrasted with the heavily oppressed lives that the characters of Fahrenheit 451 live.
On page 150, Granger passionately says to the novel's protagonist, Montag, “Stuff your eyes with wonder . . . live as if you'd drop dead in ten seconds. See the world. It's more fantastic than any dream made or paid for in factories.”
Through this declaration, Granger speaks to the need for the human spirit to experience a freedom that cannot be constructed by a ruling state or corporation. He implores Montag to experience the freedom that exists in the hearts and minds of every person, should that person choose to unchain himself from the shackles of an oppressive society and truly experience the natural beauty of the world around him.
On page 52, Mildred implores Montag to leave her alone, and, in turn, Montag replies: “Let you alone! That’s all very well, but how can I leave myself alone? We need not to be let alone. We need to be really bothered once in a while. How long is it since you were really bothered? About something important, about something real?”
Montag is lamenting the lack of meaning in his controlled life. He speaks to the need for humans to be able to be affected by, and react to, their environments. In Montag's life, his ability to be impacted in meaningful ways by the world is stifled by an oppressive state. In order for an individual to be free, one must be able to experience true meaning in life.
On pages 84–85, Faber tells Montag that there are three things necessary to change the world. He asserts that "Number one, as I said: quality of information. Number two: leisure to digest it. And number three: the right to carry out actions based on what we learn from the interaction of the first two."
This quote is significant to the theme of freedom in the novel, as Faber speaks to the importance of the freedom to receive uncensored information, the freedom to consider this information, and the freedom to carry out actions in response to information.
