The Twilight of Western Civilization

In two of his novels, "The Sound and the Fury" (1929) and "As I Lay Dying" (1930), William Faulkner depicts the modern cultural decrease of two southern families in a very similar way. This overt display of "cultural failure" seems to parallel some of Sigmund Freud's findings in four of his so-called "cultural writings," namely "Totem and Taboo" (1912-13), "Group Psychology and the Analysis of the Ego" (1921), "The Future of an Illusion (1927), and "Civilization and Its Discontents" (1930). Can we speak of a possible influence by the great Viennese thinker on the writer from the American South? And do they share any common views on the apparent depraved state of this postbellum modern society?
