The appearance of "Superman" is the inevitable result of Nietzsche's "revaluation of all values" and heroic morality, and it is also his highest moral ideal personality. In Nietzsche's view, just as we must re-create a new value system to save the degradation of human morality, we must also call out a kind of "superman" to save the tragic degradation of human beings.
Nietzsche's Superman Achievement Method
In Nietzsche's view, superman comes from all beings loyal to the earth, but superman is not the result of the evolution of all mankind, just as human beings are not the result of the evolution of all apes.
The whole human race is like an ant mountain. Among all sentient beings, only a few brave people, creators, people with a lot of power will and high quality can climb the rope hanging over the abyss, reach the other side of glory and become superman.
