In some of his works, Nietzsche reveals his preoccupations with adult education (andragogy). These concerns resurface in Thus spoke Zarathustra, a work in which the philosopher proposes three metamorphoses towards that which will eventually become his version of the "superior being". These consecutive transformations would ascribe to the human being the characteristics that belong to the camel, the lion, and the child. This article revisits Nietzsche's three metamorphoses and, through a brief reflection on the theme, posits some interpretations for these transformations. In the end, the article discusses four main lessons that we may learn from Nietzsche concerning andragogy.
