Complexity is a term created by humans. This term means everything that cannot be fully defined by a human comprehensible rule or a group of human comprehensible rules.

So human brain is complex, dna is complex, social relationships are complex, earth nature is complex, universe is complex.

Complexity probably won’t be never fully captured by humans but of course it can be observed, perceived, absorbed, elaborated, familiarized, handled, shared, talked, and why not.. loved because it is part of our extraordinary adventure and world around called life.. and of course.. we need to live.

In a certain way Complexity is the gap between actual human intellectual knowledge and full universe environment knowledge.

Complexity is the extreme knowledge frontier of a single and specific science (mathematics, physics, economy, psychology, etc) and the world of links and infinite relationships between all those sciences.

Complexity is also the point of harmony between biological pulsation, personal instinct reaction and defence, ego emotional and community expressions, science rational and logic observations, religion moral and spiritual need, art creative and imaginative explorations.

Complexity concern all aspects of life (it’s not a science-only-related method) for example family and school education processes or countries economy law and social organization.

I think all most sensible people in human history have been creating (or better configuring) in a part of their brain a sort of complex related specific “section” and we could imagine the brain divided in this five main thematic areas:

The Structure of Human Brain

Complex **

(awareness, sensible, managing)

(second strong layer intersectorial connective links)

|

|

Abstract*

(creative, imaginative)

(first basement intersectorial connective links)

(2-3 year)

|

|

Logic/Rational

(first strong elaborative basement)

(1-2 year)

|

|

Instinctual

(reactive, imitative, emotional, perceptive)

|

|

Biological

(organic, motorial)

** emerging property >> awareness, id, personality
