The word gymnastics used on that site to disqualify "everybody else's muddled middle" except for his own personal version of a "muddled middle" seems hypocritical. He talks in enough circles, and we are supposed to forget that his muddled middle is pretty much all the other muddled middles he says can't work.
I wasted so much time reading philosophy stuff in college. Its like a virus that infects the mind, "there must be a RIGHT answer!" and the infected mind goes in circles arguing with itself. Its an infinite recursive loop without a base case.
The base case is this: "would you rather be right or would you rather be happy?" its not meant to mean that we should all get on "brave new world" soma. what it does though, is get your mind out of that infinite loop of "i must know the RIGHT answer with certainty!". These sorts of topics have no certainty. They are topics worth considering, but trying to find "correct" is just missing the forest from the trees.
