that's barely anything to do with what's in beyond good and evil. he talk's about man's delusion's of truth in the opening chapter and that's about it. beyond good and evil is a massive critique of all philosophy, religion and morality whilst exploring some of his more abstract idea's like will-to-power and eternal reacurrance of the same.
i satrted a widow for one year by john irving the other day, 100 pages in and it's very good. i don't think i've ever read another writer as descriptive as he is.
Nietzsche had a serious impact on my thinking. It took me a while to understand the Will To Power concept. I figured that the Will to Power isn't a metaphysical element at all, for precisely the reason that it doesn't fit in well with the rest of his philosophy when understood metaphysically.
I have been doing quasi-research into Nietzsche's personal life and came across this interesting piece of information:

This is the Hansen Writing Ball, which was Nietzsche's typewriter that he purchased in 1865. There is part of a chapter over Nietzsche and his typewriter (and what he wrote about the machine) in the book Gramophone, Film, Typewriter by Friedrich A. Kittler, Stanford University Press, 1999: p. 198-220.
Apparently, Nietzsche was the first philosopher to use a typewriter.
And The Cider House Rules is definitly my favourite Irving book. Setting Free the Bears is a close second...haha you probably know why if you've read it. I remember I started reading it because it was one of Kurt Vonnegut's best picks.
