Thus Spoke Zarathustra: A Book for All and None

Why does Nietzsche pair Zarathustra’s first speech on the overman with the tightrope walker’s performance? How does the imagery of the tightrope walker relate to the concept of the overman? Think of specific symbols such as the rope, the two pillars, the jester, etc.

What are the underlying critiques of Christianity? How does Zarathustra represent a movement away from traditional modes of thinking, specifically religious ones? Remember specific biblical references, such as blessing the cup that overflows (3) and viewing the crucifixion as an act of pity (7). 

Hermits are referenced throughout the work and even Zarathustra transitions between isolation and civilization. What does Zarathustra find so important about a life of solitude? Does it have potential pitfalls? Do you believe that solitude is necessary to become a creator of values?
