You missed "nihilism". Yeah, believing in nothing.

I voted "Anarchism". I think I could be considered such thing. My social critiques are done from the view of anarchism, my thought is focused under the schemes of anarchy, my ideal is also anarchism. However, like Miguel de Unamuno, I believe in such ideas more as a man than as a politician, or to speak in other terms, anarchy is- for now- impossible.
