There are many textual and thematic similarities between Dante’s Inferno and Cormac McCarthy’s Outer Dark. There are also significant textual similarities between the New Testament and McCarthy’s third novel, Child of God. Juxtaposing Outer Dark and Child of God to Inferno and the New Testament, respectively, suggests a common trope that redemption requires characters’ name and repent of sin.

In both Outer Dark and Child of God, McCarthy does a masterful job of blending the elements of Appalachian Gothic to present a novel that is darkly suspenseful and grimly thought-provoking. Outer Dark focuses on the complex incestuous relationship between a brother and sister and their interaction with others. The novel follows the two on a journey through the wilderness where they must cope with the unknown qualities of that wilderness, as well as the guilt stemming from their own behaviors. In Child of God, McCarthy explores the grotesque nature of a life lived in isolation and poverty in the mountains. This novel focuses more on an individual descent into the gruesome depths that illustrate the main character’s depravity. In these two novels McCarthy examines the darker side of life in Appalachia, and forces readers to question the purpose and meaning for the characters’ lives and actions.

The moral and aesthetic complexity of Cormac McCarthy's fiction demands sophisticated theoretical reading paradigms. Intertextuality informed by poststructuralism is a theoretical approach that enables one to read the moral and aesthetic elements of McCarthy's work in productive ways. McCarthy's work is augmented by its connection to the works of other great artists and writers. As a result, McCarthy's work forces us to read his precedents from a different framework. An examination of the conversation between Martin Heidegger, Meyer Schapiro, Jacques Derrida, and Frederic Jameson about Van Gogh's A Pair of Boots creates an intertextual framework for examining the connection between Cormac McCarthy's Outer Dark and William Faulkner's Light in August. This examination demonstrates that Cormac McCarthy provides a sophisticated aesthetic and moral critique of Faulkner. This application of intertextual theory can also be applied to better understand the intertextual connections that exist within McCarthy's own canon of work. The same discussion of Van Gogh's painting can be used to understand the significance of a pair of boots in McCarthy's No Country for Old Men. This analysis demonstrates that McCarthy has moved from a privilege of postmodern aesthetics in Outer Dark to a privilege of more modern cinematic aesthetics in No Country for Old Men. This shift in aesthetics also informs the moral universe in each novel. Understanding this shift in aesthetics also provides a useful framework for understanding the connection between All the Pretty Horses and its film adapation directed by Billy Bob Thornton. The adapted film of McCarthy's novel enables a productive reading of the tensions between modernism and postmodernism in McCarthy's work.
