I'm reading Nietzsche's Beyond Good and Evil for the first time. Wow.
Dude, amazing book! Watch out though, he's a very persuasive writer - make sure you consider the broader implications of his ideas. Gotta say though, I've always preferred the semi-ironic presentation of those ideas in
Thus Spoke Zarathustra. I say semi-ironic, because I think it's clear he enjoyed the revelatory aspect of it.
I've basically been re-reading Plato and Aristotle for the past month, though the
Poetics was new to me. Going to start on Nietzsche's
The Birth of Tragedy this weekend, which should be fun. It's been a while since I last enjoyed of his inimitable writing style.
