Umguy reminds me of what I consider to be a great chart - from What Is Altitude?

The chart is useful to see the change from the "old" colors to the new color scheme from Integral Institute.

UPDATE:  One other point - from the article -

"States and stages, however, are deeply interrelated: research has shown that continued development through stages can help convert passing states into permanent traits, which is one of the more exciting findings of an Integral Approach....)"

Another attempt in this line - and I STILL haven't seen Wilber or II give credit, but maybe I've missed it - is Timothy Leary's 8 Circuit Model of Consciousness.

In regards to the Integral Institute quote above, I think the power of imprints - as permanent traits - hasn't been examined in depth, that I have seen.

Another perspective.

A good overview of Habermas, and some post-critical philosophy.  (Philosophy after the "death of objectivity".)

This is especially important, as Haberman is addressing from his framework, what Wilber is attempting to address with Integral Spirituality.   By the way, here is a review.

Namely, as is said by the article, a “contextualist challenge to the realist intuition".

More than any other work, Integral Spirituality attempts to point out a way how RELIGIOUS TRADITIONS can "transcend and include" the lessons of post-modernism, without losing the essence of the traditions.  That is a big push for Wilber, in the sense of categorizing the types of knowledge domains (inner, outer, 1st person, 2nd person, 3rd person.)
