Abstract. In this paper, I focus on Paula Satne's discussion of moral development in her "Moral Development, Repentance, and Self-affirmation". I argue that, preceding moral development, we can identify in Kant a notion of existential development that foreshadows some of Nietzsche's ideas and emphasises the existential potential of the philosopher from Königsberg.
Keywords: moral development, existential development, Enlightenment, emancipation, courage, autonomy, Paula Satne, Kant, Horace, Nietzsche.
