One of my favorites is democracy. I find the displays of loyalty they have where they self flagellate through outrage fascinating. It's also interesting how they've built a whole mythos around ideals of equality and justice that the elected high priests never stop preaching about, but evidently do not follow themselves at all. I also find it insane how seriously their intellectuals take their purity wars and how viciously they denounce blasphemy for any kind of doubt they perceive over their hugely dogmatic beliefs.

Another interesting one is Empiricism, but since their apostoles seem to be unaware or unwilling to accept it being a belief system at all, rather considering it the unquestionable nature of reality itself and can get so defensive and upset when faced with other highly speculative and superstitious bliefs, I'll just say I find its apotheotic aspirations for mankind inspiring.

Orthodox Economic theory's intricate divination rituals and soothsaying clergypeople also wonder me, and their sacred sport of "business", a game of complex trading systems and rule circumvention has a crazy rich pantheon of heroes, profets and deities.
