Why does Ray Bradbury refer to Schopenhaur in his book Farenheit 451?What does Bradbury imply about Schopenhauer's philosophy?

Towards the end of the book, Bradbury has one of the "book
covers" be Schopenhauer.  He is among such people as Mark Twain and Jonathan
Swift.

What this implies about Schopenhauer is that he is
"dangerous" like these other men.  The other men here were pretty cynical and were also
pretty rebellious.  Neither of these is a trait that the society in this book would
like.

Specifically, Arthur Schopenhauer was a pretty
pessimistic thinker.  He concluded that people could never have what they want and that
they should try to get rid of their desires.  This also goes against what this society
thought.
