I'm not quite sure I can answer the question. I certainly have no major, world(view)-shaking Cause which is driving me to improve my strength. For what it's worth, I've had this general idea that being wrong is a bad idea for as long as I can remember. Suggestions like "you should hold these beliefs, they will make your life happier" always sounded just insane - as crazy as "you should drink this liquor, it will make your commute less boring". From that standpoint, it feels like what I have to protect is just the things I care about in the world - my own life, the lives of the people around me, the lives of humans in general. That's it.

OB then LW were the 'step beyond' to take after philosophy, not that I was seriously studying it. to be honest I don't think there's much going on these day new-topic-wise, so I'm here less often. but I do come back whenever I'm bored, so at first "pure desire to learn" then "entertainment" would be my reasons .. oh and a major part of my goals in life is formed by religion, ie. saving humanity from itself and whatever follows, this is more ideological than actual at this point in time, but anyway, that goal is furthered by learning more about AI/futurism, the rationality part less so, as I already had an intuitive grasp of it you could say, and really all it takes is reading the sequences with their occasional flaws/too strong assertions, the futurism part is more speculative-and interesting- so it's my main focus, along with the moral questions it brings, though there is no dichotomy to speak of if you consider this a personal blog rather than book or something similar. hope this helped :)
