I like philosophical books, both pure philosophy and fictional stuff with a tendency to "what binds creation's inmost energies". There were two years in my life where I read Nietzsche's "Thus spake Zarathustra" almost daily and I still know large passages by heart. Then I got into Arthur Schopenhauer and read his complete works twice (about 5000 pages). I had heard that Wagner wrote his "Tristan" after having read Schopenhauer's main work "The world as will and representation", so this is how I bumped into that and it made me a different person. I've never found that much wisdom in any writing, apart from his rants against Hegel and his followers. But as a result I can say that the "Tristan" doesn't have much to do with Schopenhauer and the libretto is influenced by Novalis anyway.I've read almost everything from Dostoevsky, Oscar Wilde, and several books from Hermann Hesse. Currently I read Nikos Kazantzaki's "The last temptation of Christ".
I've recently finished reading the King James Bible (the New English and Good News versions are ***).At the moment I'm reading Crime and Punishment (Dostoevsky), Unfinished Tales (J.R.R. Tolkien), The Divine Comedy (Dante) and The Count of Monte Cristo (Dumas). A lot at the same time.
