Dear Amazigh,
Thank you for your visit.
Some your observations :
'... the duality was obvious to the Egyptians, Greeks, etc.. , And especially the Chinese...
For me the question is quite different : why we do not have yet flushed the irrefutable arguments that prove that the universe is binary, dualistic...
Today, Einstein's relativity is well understood in the physical domain. It explains very well the two points of view of two people moving relative to each other...
Finally, I would like to conjecture that:
-The first principle that governs the universe is Duality. The principle of conservation has come after. Give the same interest to duality that to motion, and things will better.
-We know matter is dual as well as the light is. So if duality is everywhere, how to recognize this fact, as we did for the motion ?
-The Duality is the common language by excellence, the integral link between all the elements of nature, the machine code of the universe '
may suggest some analogies with field findings of structural anthropologists. In particular,French anthropologist Levi-Strauss made reference to 353 duality based different myths in order to prove that the human brain does have a tendency to operate with binary oppositions in all sorts of situations. This result is foundation of structural anthropology and semantic algebra of myths today. However, the sceptics were right as well, because human brain can operate in other ways also. Thus, a fully satisfactory model of the human mind would contain many unknown features which do not occur merely in digital computers. I suppose you can improve your structural linguistic analysis of oppositions by Jakobson's technique based on conjecture that ' in all the languages of the world the complex systems of oppositions between the phonemes are no more than a multi-directional elaboration of a more complex system which is common to all, namely the contrast between consonant and vowel, which through the working of double opposition between compact and diffuse, acute and grave...'
