Cormac McCarthy's representation of the comic theories of the carnivalesque, incongruity, and absurdism by the antagonists of Blood Meridian and No Country for Old Men demonstrates the unique and ostensible power of humor over (or at least, its awareness of and reconciliation to the absurdity of) death; it also emphasizes the supreme power and influence of humor as a means for destroying other institutions and philosophies which claim knowledge or authority but fail to sustain individuals in times of crisis. This makes humor a formidable factor in determining and justifying the outcome of human interactions and in defining the strengths and limitations of McCarthy's antagonists.

Memory and nostalgia work in complex, paradoxical ways in Cormac McCarthy's No Country for Old Men and The Road, both haunting the main protagonists, Sheriff Ed Tom Bell and the father, as well as bringing them to crucial realizations. These men give up the traditional hero role for the more meaningful and generative image of “carrying the fire,” which unites these two novels. Carrying the fire represents a memorial and nostalgic longing for home and family. Bell and the father attain this vision because of their obsession with the past, and because of their struggle with memory and nostalgia. Memory, for these characters, has both personal and collective dimensions. Nostalgia, likewise, has a dual function, following Svetlana Boym's definition of nostalgics as being capable of restorative and reflective longing for the past. Family, or Paul Ricœur’s theory of close relations, bridges the gap between the conflicts of memory and nostalgia, acting as the means by which they understand this vision of carrying the fire while also embodying it. Additionally, the duality of both memory and nostalgia drive Bell and the father to seek for a prophetic vision, for stability in the past to deal with the threats in the present, which appears in the narrative structures of each novel.

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.
