The aim of this article is to fill a certain gap in the assessment of relativism by drawing on Joseph Ratzinger’s (1927–2022) criticism of the normative transformation since Kant. During the Enlightenment, Natural Law was doubted as a cultural feature of Christianity that had no bearing on pluralist society. Consequently, this jurisprudential tradition underwent de-Hellenization and branched out in radical directions, the most decisive of which was Kant’s post-metaphysical system of natural values. Positivism and German Idealism attempted to restore the (...) unity of philosophy that Kant’s philosophy had disrupted. Yet even more influentially, in the nineteenth and twentieth centuries it was Marxism that relativized the doxological aspect of normativity by emphasizing the importance of praxis. Since philosophy became neither an exact science as Kant had conceived it to be, nor a practical programme for social justice as Marxism had promised, the Existentialists, and particularly Sartre, advocated a more radical philosophy of freedom. Ratzinger argues that despite the nuances of post-Kantian philosophy, Positivism, Existentialism, and Marxism failed to comprehend the human condition and that the positivist method resulted in an overwhelming relativism that has reduced normativity to a matter of correct procedures rather than regarding it as the foundation of the inviolable dignity of the human being.
