The essay analyses a commentary that Jung wrote in English, from 1934 to 1939, concerning Nietzsche’s Thus Spoke Zarathustra (a partial Italian translation of the commentary was published in 2011). The depth of the Jungian interpretation is revealed, showing how the text had been analyzed in all its folds. The author of the essay notes how Jung recognizes the philosophical-existential issues that bring Nietzsche to the theory of the Übermensch, and how Jung imputes numerous aporias of the Nietzschean text to having mixed a "numinous" idea like the Übermensch to illuministic-rational categories. The author sees in the devaluation of rational categories and of intersubjectivity a point in common between Nietzsche and Jung.
