In this paper, Professor Octavi Fullat (born 1928) outlines the thinking of Friedrich Nietzsche, who is well known to have announced the death of God. After an orthodox Catholic upbringing, Fullat experienced a genuine upheaval when he encountered Nietzsche’s works. Fascinated by Heidegger’s interpretation of Nietzsche’s philosophy, Fullat saw that the principles and values of western culture were under threat of collapse. Concerned since youth to find a foundation for morality beyond religious injunction, he was stunned when he read Nietzsche and was forced to rethink not only the bases of morality but also the foundation of western culture, that is, the culture forged out of the Jewish, Greek and Roman synthesis that had crystallized in Christianity. Ultimately, Fullat held that the death of Nietzsche, in 1900, marked the beginning of what has since been called “postmodernity”.
