Relation to the eternal recurrence

The Übermensch shares a place of prominence in Thus Spoke Zarathustra with another of Nietzsche's key concepts: the eternal recurrence of the same. Several interpretations for this fact have been offered.
Laurence Lampert suggests that the eternal recurrence replaces the Übermensch as the object of serious aspiration. This is in part due to the fact that even the Übermensch can appear like an other-worldly hope. The Übermensch lies in the future — no historical figures have ever been Übermenschen — and so still represents a sort of eschatological redemption in some future time.
Stanley Rosen, on the other hand, suggests that the doctrine of eternal return is an esoteric ruse meant to save the concept of the Übermensch from the charge of Idealism. Rather than positing an as-yet unexperienced perfection, Nietzsche would be the prophet of something that has occurred a countless number of times in the past.
Others maintain that willing the eternal recurrence of the same is a necessary step if the Übermensch is to create new values, untainted by the spirit of gravity or asceticism. Values involve a rank-ordering of things, and so are inseparable from approval and disapproval; yet it was dissatisfaction that prompted men to seek refuge in other-worldliness and embrace other-worldly values. Therefore, it could seem that the Übermensch, in being devoted to any values at all, would necessarily fail to create values that did not share some bit of asceticism. Willing the eternal recurrence is presented as accepting the existence of the low while still recognizing it as the low, and thus as overcoming the spirit of gravity or asceticism.
Still others suggest that one must have the strength of the Übermensch in order to will the eternal recurrence of the same; that is, only the Übermensch will have the strength to fully accept all of his past life, including his failures and misdeeds, and to truly will their eternal return. This action nearly kills Zarathustra, for example, and most human beings cannot avoid other-worldliness because they really are sick, not because of any choice they made.
