That is pretty much it, but Nietzsche also regarded Eternal Recurrence as a challenge and ultimatum of sorts; the superior type could be confronted with the prospect of reliving every aspect of life with all of its horrors, pain, suffering, and uncertainty, identically down to the last detail for eternity and still be able to say "yes" to life.
That was one respect in which he exalted the ancient Greeks; that they could embrace a tragic view of existence and still possess the fortitude to remain life-affirming.
This is in direct contrast to the major religions of the world that glorify suffering for its own sake and advocate withdrawal from the world.
Ah! The use of pain in developing the Ubermensch.
In relation to this discussion, it is interesting, to me at least, that ancient Judaism actually had a view more consistent with Nietzsche's idea. There was no actual division of humans into physical and "spiritual". There was no seperate soul until religious peddlers needed a fake ailment to cure.
Thanks for the explanation.
