[Augusto] Del Noce’s real genius was his prophetic insight into the rise of Western irreligion. He saw that Marxism “won” the war of ideas, even as it collapsed as a theory, by establishing the economic dimension of man as humanity’s defining reality. For Del Noce, the West “defeated” Marxism not by reaffirming biblical morality or Christian anthropology but by quietly shedding both. Western countries won by outproducing Marxist systems on their own terms, with material results—superior science, superior technology, more and better consumer goods. The dark side of technology, Del Noce argued, is a passion for “total revolution”—permanent revolution against the past doing business as innovation. The byproducts of its success have been religious agnosticism, sexual liberation and radical secularism. By the time of his death, Del Noce viewed much of Western society, despite its Christian residue, as the most thoroughly atheist in history, a feat achieved not by persecuting God, but by ignoring and rendering him irrelevant.
