Themes are the fundamental and often universal ideas explored in a literary work.
The fear of death lies at the center of White Noise. As Babette notes when she confesses her fear to Jack, “What is more underlying than death?” Everything in the novel—from Hitler to the supermarket, from the airborne toxic event to the white noise of the novel’s title—circles back to human beings’ primal, deep-seated fear of dying. DeLillo’s novel details how modern life attempts to push this fear out of sight, and yet, as in the character of Jack Gladney, the fear continues to resurface and fill us with dread.
Different characters in the novel approach death in different, often contradictory ways. Jack approaches it with terror. Heinrich faces death dispassionately and analytically. Murray sees death all around him and remains continually fascinated and engaged by it. Winnie Richards notes that death adds texture to life, while Jack and Babette would give anything to avoid it. Jack and Babette speculate that death might be nothing more than an eternal hum of white noise: detached bits of data, garbled gibberish, and meaningless sounds, all vibrating at an equal frequency so that nothing in particular stands out and everything remains potentially significant. However, this description could also apply to Jack’s life and to White Noise in general. While there is a general plotline in the novel, the bulk of the book is comprised of digressions, tangential conversations, and snippets of overheard machines and broadcasts. Though DeLillo avoids drawing any distinct conclusions himself, preferring to leave the novel in an open state, this close relationship between life, death, and white noise might mean that death lingers menacingly in the background of our lives, or it might mean that death, as an inextricable part of life, represents something we shouldn’t be afraid of. Both attitudes seem supported by the novel, which presents white noise—and the stronger, yet more elusive strain of sound that people like Murray and Jack detect behind that white noise—as simultaneously a thing of dread and of intangible transcendence.
Throughout White Noise, the authentic and the artificial often blur together, and substance seems interchangeable with surface. This confusion between appearance and reality represents an essential part of Jack’s own existence. Although Jack has created a venerable, professorial persona for himself, he remains painfully aware of the total fabrication of this character. Aided by the distinguished outfits and the weighty-sounding professional name, Jack manages to hide the fact that he lacks the ability to speak German, a seemingly basic skill for the field of Hitler studies. Jack is driven to learn the language only when an academic conference threatens to expose his lie—not in order to study his subject more deeply. Jack, in turn, is only invested in Hitler as a surface entity and seems more preoccupied with the cultural myths surrounding Hitler than in the historical facts about the man. Jack relies on Hitler’s larger, more powerful persona to bolster his own fragile sense of self-worth and self-identity, capitalizing on Hitler’s surface to build up his own.
Jack feels inadequate because, in his mind, artifice is inherently inferior to reality. However, other moments in the novel contradict this position. When Murray and Jack visit the Most Photographed Barn in America, for example, Murray argues that the barn itself isn’t intrinsically significant. Rather, the fact that countless tourists have come to visit the location gives the site meaning and value. Each time a tourist comes to admire this essentially empty and meaningless structure, he or she adds to the psychic energy surrounding the barn. The barn becomes relevant because many people have invested in the image of the barn. In Murray’s opinion, no genuine difference between surface and substance exists.
At the same time, DeLillo satirizes postmodern human beings’ inability to discern the genuine from the fabricated. The SIMUVAC, or Simulated Evacuation, is perhaps the most extreme example of the tension between what is real and what is artificial. For SIMUVAC, real events, such as the airborne toxic event—which was itself caused by a derivative of an original chemical—are used to prepare for later simulations, and later simulations are used to prepare for other simulations. In this environment, where technology allows for endless duplication, it becomes increasingly difficult to ascertain where reality ends and replication begins.
In White Noise, the pervasive presence of technology proves both menacing and comforting. Throughout the novel, in counterpoint to the human babble of Jack’s friends, family, and neighbors, modern technology asserts itself through the humming of machines and the constant stream of media sounds and images. Technology has become as much a part of the texture of daily of life as humans are themselves. In fact, the two seem inextricable, as DeLillo’s narrative weaves seamlessly between human and mechanical voices.
