Wagner: "also, watch out, your friend Paul Ree is a jew."
Nietzsche: "watch out for...what exactly?"
Wagner: "just watch out..."

When Nietzsche was young he admired Wagner greatly, and they became friends. Wagner thought Nietzsche's philosophy would provide a grounding to his own project and his beliefs about his music. Wagner thought art and aesthetics was prior to and superior to moral life, and society should be run by the few superior individuals who were capable of creating such art. Eventually they split, in a large part due to Wagner's raging anti-semitism. Despite this, Nietzsche sometimes get linked to anti-semitism and German nationalism (largely due to the influence of his sister after his death), even though he thought nationalism in all forms was ridiculous, and despised the anti-semitism in the German culture at the time. Wagner also tried to get Nietzsche to break off his friendship with some of his Jewish friends, such as Paul Rée, which Nietzsche refused to do.
Nietzsche ended up turning away from Wagner's ideas entirely, and in fact wrote lengthy essays attacking him later in life, for various reasons.

History is nothing more than slow process of understanding Hegel

What? Are you expecting me to explain Hegel here? You are a fool, no one can explain Hegel except for Hegel, and even he can't explain it.

"What about a retirement plan? Should we be investing?"
"Investing? No, all that will be wiped out when the workers take control. A communist revolution should be your retirement plan."

Besides, what are you so mad about? It's not like you weren't going to destroy yourselves in the next hundreds years or so anyway.

"What is theoretical basis for not wanting to destroy the planet? Come on guys, just...can we not?"
