Remain faithful to the earth, my brothers, with the power of your virtue. Let your gift-giving love and your knowledge serve the meaning of the earth. Thus I beg and beseech you. Do not let them fly away from earthly things and beat with their wings against eternal walls. Alas, there has always been so much virtue that has flown away. Lead back to the earth the virtue that flew away, as I do—back to the body, back to life, that it may give the earth a meaning, a human meaning.

Nietzsche's key ideas include the "death of God" the Übermensch the eternal recurrence the Apollonian and Dionysian dichotomy perspectivism and the will to power. His sister Elisabeth Förster-Nietzsche acted as curator and editor of Nietzsche's manuscripts during his illness. [citation needed].
