Buddhism and Integrative Complexity I noticed a coincidence between something I read in a book by Thich Nhat Hanh, and an article on research about a psychological phenomenon known to facilitate inner and outer peace. My question is: What Buddhist concepts are similar or have something in common with the "integration" and "differentiation" phenomenon mentioned below? My guess is emptiness and impermanence, I could be wrong about those and doubtless there are others. 

Here's the coincidence.

Years ago I was reading Zen Keys by Thich Nhat Hanh. I found it had my mind going in many interesting directions. 

I saw some parts of the book, like those describing impermanence, encouraging the Differentiation of things. A book isn't a book. It's made of wood and glue, was put together by a machine somewhere and hauled to the book store by a guy in a truck. The book is made up of many non-book elements. Everything changes, so the book itself isn't even that book over the smallest amount of time depending one which features you choose to measure. 

But there was also a call for Integration. Even as we distinguish between the book and the truck and the guy hauling the books in the truck to the bookstore, they are all part of the process leading to the experience of reading the book. The book might have one meaning to one reader, and a different meaning to a different reader. So many things depend on the context bringing them together. The same elements at a different time and place produce a different experience. The individual elements create the here and now into a unified whole, any part of which alters the thing when changed. 

With my math background I was inclined to think of these things as Integration and Differentiation, just as helpful mnemonics, they are pretty different from the math concepts. 

A few months back I was reading about Integrative Complexity. 

"The measure of integrative complexity has two components: differentiation and integration. Differentiation refers to the perception[or weighing] of different dimensions[or qualities] when considering an issue. Integration refers to the recognition of cognitive connections among differentiated dimensions or perspectives.1"

It has some things in common with what Thich Nhat Hanh was talking about, in terms of understanding of all things as composed of not-that-thing elements. One can find similarities in different things, and differences in similar things. The interplay of those techniques are proving conducive to both inner and outer peace according to the researchers.
While I don't have any comments on the individual concepts of Differentiation and Integration, reading that wikipedia article about Integrative Complexity as a style of thinking - strikes me as being very similar to the &quot;Buddha can see from all perspectives&quot; idea I presented in my answer here.
Quoting the wikipedia:

Integrative Complexity is ...recognition and integration of multiple perspectives and possibilities and their interrelated contingencies.
For example, it could take the form of explaining why someone may view an event in a different way or in what ways a compromise could be made between conflicting values.

So by this definition Buddha is the champion of Integrative Complexity.
That said, these parts:

Integratively complex thinkers are also more prone to defer to others or put off making a decision when faced with difficult cost–benefit decisions.

and

Additionally, while integratively complex thinkers are more likely to reach a mutually advantageous compromise when dealing with reasonable opponents, unreasonable opponents are much more likely to be able to exploit them.

-- do not sound relevant at all. Perhaps whoever wrote this did not realize that one's ability to integrate diff. perspectives does not preclude one from having clear agenda. Buddha knows what is ultimately good (cessation of suffering!) and has no problem utilizing his Integrative Complexity skills to use people's own motives to their ultimate good.
So perhaps we could say that Buddha is the champion of Integrative Complexity AND ethics.
