41. Beyond Good and Evil by Friedrich Nietzsche
I read this for a class, but I didn't have the time to devote to it that it clearly deserves. The prose is beautiful, but together, I'm not sure what it all means-and many think that was deliberate on the part of the author.
If you want to find justification for murder here, you can.
If you want to find atheism here, you can.
If you want to find any way of looking at the world differently, of looking at the world the way you've always felt it should be or never realized before now it could be-this is the apple you want to bite.
"You want to live 'according to nature'? O you noble Stoics, what fradulent words! Think of a being such as nature is, prodigal beyond measure, indifferent beyond measure, without aims or intentions, without mercy or justice...think of indifference itself as a power-how could you live according to such indifference?" (Section 9)
