Analysis Of Nietzsche's 'Thus Spoke Zarathustra'

Nietzsche's 'Thus Spoke Zarathustra' isbook stylized in a similar fashion to the New Testament, separated into four parts that deal with different topics under a general theme, Nietzsche's concept of the eternal recurrence. It deals with a plethora of interesting topics and concepts, the most infamous being the 'idea of the eternal recurrence of the same', that 'God is dead' and man as species must aspire to become the 'Ubermensch', otherwise known as the overman or superman. The overman, as described by Nietzsche, is the result of a singular endeavor towards knowledge and power--someone with the capabilities to take responsibility for each moment of his life. Man is something to be surpassed--the overman is the next level of evolution. In
The overman is the meaning of the earth. Let your will say: the overman shall be the meaning of the earth!

As no overman has ever existed, and this ideal is created by Nietzsche, who, like the rest of society is only a man, it begs the question, is Nietzsche credible enough to dictate who the leader of mankind should be? The ideal of the overman includes ignoring societal boundaries in favour of ones own plan. If no universal values are in place, would man fall into total chaos, committing dangerous and immoral acts? While Nietzsche makes it clear that the overman is not someone who is immoral simply for the sake of being immoral, but rather that he is a lover of knowledge seeking an existence higher than the one we currently accept, some of his constructs can and have been misconstrued in the past. The overman has been compared to that of Nazi ideology, the parallels being that both believe in ignoring morals to achieve a higher power. I think if the definition of the 'power' the overman is seeking were more fleshed out, there would be less room for misconception and a clearer guideline as to what aspects really matter to becoming
