Full Idea
Nietzsche recommends an extreme version of perspectivism in holding that a person's view of the world is a function of that person's life-affirming (Heraclitean) or life-denying (Parmenidean) personality.
Clarification
Heraclitus and Parmenides were early Greek philosophers
Gist of Idea
Nietzsche's perspectivism says our worldview depends on our personality

A Reaction
Fogelin recommends Nehamas on this topic. I am not convinced Nietzsche takes such an individual view as is implied here. See Idea 4420, for example. This view is in tune with Charles Taylor's view that our values shape our understanding of our selves.
