Named after a famous publisher, Professor Faber competes with Beatty in the struggle for Montag’s mind. His psychological control over Montag may not be as complete and menacing as Beatty’s, but he does manipulate Montag via his two-way radio with the hope of accomplishing the rebellious acts that his cowardice has prevented him from doing himself.

As a literal voice in Montag’s head, Faber’s role and motivations throughout the novel are complex. At times, he tries to help Montag think independently, and, at other times, he tries to dominate him. When Montag first visits Faber’s house, for example, he helps him come to terms with why his life feels so empty. He explains that the power of books is in what they say and that having access to such rich stories can empower people to think critically and act. This moment of enlightenment inspires Montag’s plan to burn down firemen’s houses, setting the stage for the remainder of the plot to unfold. Once Montag sets out to execute his plan, however, Faber becomes more controlling. His instructions to Montag may seem well-intentioned, such as when he implores him to stop discussing books in front of Mildred and her friends, but he ultimately admits that he will “say [his] say” and try to convince him of his belief system. Despite this darker side of his character, Montag still looks up to Faber and clings to the ideas of intellectual freedom that he represents. He runs back to him after killing Beatty, and they both end up helping each other move on to the next stage of their journey. Faber’s relationship with Montag allows him to develop as a character by showing him how powerful taking action against injustice can be. Exhilarated by their work together, Faber finally overcomes his cowardice and sets out on his own.
