Finally finished this little book (Finnish translation) which is supposed to be an introduction to Nietzsche's philosophy. I honestly found it the most boring book ever, mostly because it's just an incoherent stream of thoughts and excerpts with no sane structure.
Okay, maybe philosophy is supposed to be like that, and Nietzsche's writing style certainly seems to match this approach. I just don't like it particularly.
Perhaps the most rewarding part of the book was the last ten pages, where Hayman describes Nietzsche lapsing into (assumed) insanity, through his preposterous fantasies of world domination, and later his inability to distinguish himself from fictional characters.
It's intriguing to think that after declaring God dead and entering an impossible world of absolute objectivity, Nietzsche just couldn't deal with himself any further. If you rule out both emotions and logic, there's nothing left to live on. On the other hand, there are speculations that Nietzsche in fact simulated his insanity, maybe just to prove some point to his contemporaries. Or maybe he just wanted an "honorable" exit after losing interest in philosophy, thinking he'd solved everything.
Anyway, I won't pretend to be an expert here, I haven't actually read any of Nietzsche's books. Maybe later...
