Reading The 4th Turning by Neil Howe and his Universal Theory and Ideas I got to wondering about “theories of everything” in general and came upon this older book.  I’m lightly familiar with Ken Wilber’s ideas and yes, I have problems with them.  I’m pretty secure in my own beliefs.

Wilber is fairly well known from the New Age ideas of the 1970s. He’s not necessarily universally acclaimed but he is still getting published. That said, he has plenty of critics (including moi). But he has some interesting things to say in this book and in his other later works where he applies these earlier theories in many areas. Basically, I find that too many of these psychology/philosophy ideas are simply new ways to divide up the world and we need more ways to connect with compassion.  

Overview and writings: https://en.wikipedia.org/wiki/Ken_Wilber

His is a set of “complex, cutting-edge theories that integrate the realms of body, mind, soul, and spirit” –  Okay fine – but it seems to me they end up dividing humans into “more evolved” and “less evolved” based on the extent to which their ideas mesh with Wilber’s. (Over-simplified: more compassion equals more advanced.)   

From Carol Gilligan comes some much more recent ideas on moral development which is another example of dividing ourselves so that some groups are labeled “higher” or “more developed.”    (Wilber is not mentioned.)
