....I'm about midway through "Thus Spoke Zarathustra".
Most people have the Ubermensch concept kinda wrong, and he also seems to be quoted out of context a lot. The book itself is actually quite fascinating. Part poetry, part philosophy, part narrative. He can work an extended metaphor as eloquently as anyone....not bonus points in philosophy, but something.
No one is going to agree with everything he says, mainly because he talks about a LOT of different topics. And there's some sections I absolutely hate (the sections on women are particularly archaic). But the central idea revolves around what exactly makes up the characteristics of the Ubermensch, and it's an interesting study. Mainly (and again, I run the risk of paraphrasing and simplifying, which is dangerous at best with Nietzsche) the Ubermensch is a person who is a total master of that which is one's own self, to the point where social convention and popular thought are as nothing to him/her. There are many other tenets of the Ubermensch, but that seems to be the common thread between them....and it is a noble one. Social duty is shunned in favor of being true to oneself.
It is an easy concept to understand, but startling when one fully grasps the implications of becoming such a person. Nietzsche captures it all very well.
...entire sections can be discarded, ignored, or refuted easily enough...and it's easy to see why he caused so much controversy and philosophical backlash. But I can't help but enjoy it, and feel like I'm gaining something worthwhile out of it beyond mere aesthetic pleasure (which can be its own noble end sometimes).
