This paper argues that Nietzsche is a panpsychist. Panpsychism holds that mental features are ubiquitous and fundamental in reality. I first argue that Nietzsche’s rejection of Cartesian dualism leads him to substance monism. To better understand his monism, I examine Nietzsche’s rejection of Newtonian atomism. Nietzsche holds that bundles of forces, or will to power, are more fundamental than hard, extended atoms. So, will to power is fundamental. I then investigate Nietzsche’s remarks on organic and inorganic nature to show that (...) he believes both are will to power. So, will to power is ubiquitous. The final step to panpsychism is to show that Nietzsche believes will to power exhibits mental qualities. If all goes well, it should emerge that Nietzsche thinks mental features are fundamental and ubiquitous in reality. (shrink)
