Mawibse, Nietzsche i assume? He's a madman, good writer though.
Anyway, my own thoughts on free will are all based on the undeniable awareness of itself (which is proven by doubt, which is the only thing one cannot doubt - the one thing Descartes based his philosophy on when he 'started all over'). It is my firm belief (and i'm getting closer to getting logical proof for this stand) that awareness cannot be explained only through physicial processes and that it can be traced back to a more pure level of reality which be can get a glance of through conscience. Read Immanuel Kant: He made his so-called Copernican turn dismissing the idea that we can see reality objectively and embraced the idea that we cannot go round some tools we need to interpret reality: time, space, causality, etc. He listed twelve (i think) of those categories. These 'glasses' we are wearing all the time are disguising this more pure reality and turn it into how we see the world. However, awareness cannot be explained in terms of these categories. Not because of a limited knowledge right now but because of a fundamental incompatibility. I've written an essay on the 'proof' (if you can speak of proof when it comes to philosophy) of this, but this is the basic idea.
