Nietzsche should be studied alongside Plato. I can't remember the quote, but Nietzsche emphasized that the strength of a person could be judged by the strength of the enemies he choses, and Nietzsche definitely chooses Plato as his arch-nemesis. Some people - like me - even think that Beyond Good and Evil is a direct reply to The Republic. Many amazing and sometimes disturbing lines of thought emerge if BG&E is read as if it were part of the dialogue with Socrates.
