Anti-Nihilist

This is the sort of character that goes by doctrines along the lines of "Don't cling to pain. Don't expect happiness. Don't fear loss. Accept reality as it is. Enjoy the good. Endure the bad. Don't make a big deal out of anything. Be selfless, and unconditionally kind and just, without ever expecting a reward. We're all going to end up as piles of dust, so why not be nice to each other and get those pleasant fuzzies?
