Full Idea
Nietzsche's thought includes both a metaphysics and a perspectivism, once these are more complexly grasped. But I argue that the metaphysics is basic: it's an ontology of perspectives.
Gist of Idea
Nietzsche has a metaphysics, as well as perspectives - the ontology is the perspectives

A Reaction
Very good. If it was just gormless relativism, which is what many people hope for in Nietzsche, why is it many perspectives? If they are just relative, having lots of them is no help. The point is they sum, and increase verisimilitude.
