The Nz book is coming along. I have a draft of the “Overture,” which is an overview of his life and philosophy; a draft of “Act I,” which is about the misty romantic metaphysics lying being Birth of Tragedy and Untimely Meditations — roughly, the idea is that Greek drama and Wagnerian opera both have the power to disclose the tragedy of human existence and offer us a reconciliation to it; and I’m partway through a draft of “Act II,” which covers Nz’s break with the misty metaphysics and Wagner and his turn toward naturalism in Human, all too Human.
I spend some time trying to explain what naturalism is. Here’s my idea: take the Kantian distinction between appearances (everything causally related in space and time) and things in themselves (ultimate reality, outside of space and time), do away with the things in themselves, and you’ve got naturalism. That seems too easy, though, so I wonder what I am missing. Maybe something about method — how the empirical sciences determine what counts as real? But that doesn’t sound right, since the empirical sciences undergo massive change, and I don’t want to end up saying electrons didn’t exist in 1500!
