 Famously, the book concludes with Nietzsche’s first introduction of his thought of eternal recurrence, which is supposed to place “The greatest weight” on each event through its suggestion that our life is good only if, upon imagining its return in every detail, we can affirm it as it is (GS 341). After that penultimate section, Nietzsche quotes the first section of Thus Spoke Zarathustra, which returns repeatedly to the same theme of affirmation (see, e.g., Z I, 1, 5, 17, 21, 22; II, 7, 12, 20; III, 3, 7, 13, 16; et passim; BGE 56; TI VIII, 6 and IX, 49).
