Jules, I am greatly enjoying your writing (I am both an author and a publisher). And I think here you have done Nietzsche a disservice. You pointed out there are many Nietzsches. Indeed, he did not set out with monolithic philosophy to preach. His thinking evolved and shifted. Most important, his idea of the ubermench is simply not a being that can be bred - it is a spiritual state of constant will to overcome one’s own weaknesses. Indeed, N’s words were taken and twisted, horribly, by exactly the kind of people Nietzsche, I believe, despised. I would urge you to take a look at this book: The Journey to Inner Power by Shai Tubali. The author gets the fundamental problem Nietzsche takes on (how do we make meaning for ourselves, now that we have killed God?), and has distilled his solution (we can will ourselves to evolve spiritually through a demanding internal process of overcoming).

Think about it: Nietzsche himself was weak, jobless, friendless (mostly) . Yes he did not despise himself — no, he used his illness to overcome pain, to overcome loneliness, and thus to think and write with rare brilliance. That is the path of overcoming he set for us to follow.
