Was his "will to health" helpful in achieving health? In other words how is "willing" something helpful at all?
— Agustino
Nietzsche said Will to health, not health. Living for rewards is not the point here. Who Said anything about something being helpful? Nietzsche spoke about psycholoical truths if You Will. As You know, he wanted life to be sacred and beautiful as it IS, not as people wish it to be. That is the point. Life is what it is, beyond good and evil.
How shall we handle this then?
— Agustino
By embracing your life, affirming it instead of wishing for something else, live despite of, not living in the past with regrets for example. Affirmation and Amor fati is how to handle it. But there is so much more to say here. This is just basics on the surface.
"quite the contrary, suffering for God is good in Christianity, why do you think Christianity has all the martyrs that it does?"
Yes, christianity made a whole system of redemption out of suffering. But why? Because they couldnt accept suffering. And christianity still finds suffering bad, otherwise there would be no plan to end it in the next world. Suffering for a reward, basically... About the martyrs; well. Psychologically their behavior wouldnt be hard to understand according to Nietzsche.
"Yes, N was incapable to do this. He had no means."
Ridiculous. Read Nietzsche and You see e had. One example of a man worthy of respect according to Nietzsche is Beethoven: He affirmed life and lived out his call despite everything. He Because deaf; yet he continued to compose and as a result created perhaps the greatest music ever written.
"A childish and stupid idea in the end, for no one can re-live his life anyway."
Just Your opinion. I could say the same about christianity. "A childish and stupid Idea anyway. No one will be raised from the dead or have an immortal soul and an eternal life anyway". Eternal recurrence is an old Idea. But Nietzsche mainly used it as a thought experiment.
"Nietzsche wanted to know the Truth apart from Christ, but there is no such Truth. That is why he concluded that truth is ugly. Yes, the truth of the human condition is ugly, that's exactly why we need the Truth"
Also your values and opinions. To me, Beethoven's life isnt ugly But beautiful. Though I have to admit that Jesus life too was beautiful and admirable, and I DONT believe that christianity is a silly idea. I dont agree with Nietzsche entirely about christianity, because I think he went too far. I like Dostoevsky. And Blake.
