It were the height of presumption to attempt to fix any particular interpretation of my own to the words of this song. With what has gone before, the reader, while reading it as poetry, should be able to seek and find his own meaning in it. The doctrine of the Eternal Recurrence appears for the last time here, in an art-form. Nietzsche lays stress upon the fact that all happiness, all delight, longs for repetitions, and just as a child cries "Again! Again!" to the adult who happens to be amusing him; so the man who sees a meaning, and a joyful meaning, in existence must also cry "Again!" and yet "Again!" to all his life.
