Without an external fixed point of reference or guide, we can't walk straight. It's something sciency that scientists are still trying to wrap their heads around. So basically, how I see it is (being the arts student that I am) humans are really quite pointless without a real and material goal to aim for. In other words, just thinking it does not make it so. Haha! Is that abstract enough for the weekend?
npr is awesome like that with their videos and articles. Have a good weekend guys!
