FeedBack: -re-e-involution-

ردود الفعل: ثورة، تطور، ارتداد

反馈:革命,进化,退化

Cybernetics has grown learning from living systems.

Living systems are living in landscapes, where living processes ocurrs ignoring any barrier between "Living" or "not Living".realms. Organisms make themselves a dynamic frontier within living and not living. Certain Bacteria Do have sleep during millions years inside Salt Rocks. Tardigrada may survive in physical circumstances letal for many other organisms...

Cybernetics was born as the science of control and communication.

The second cybernetics put the emphasis in feedback and in Homeorrhesis, as an active process for recreating and evolution of organisms, and structures. They are possitive feedbacks which don't stabilize the system, but on the contrary, allows it to cross new roads in ist development and evolution.

With mobil phone revolution, we see how interaction in communication is independent of any fixed point in space, allowing and faculting agents for a better and continuous feedback.

Assembly is an idea well acompassed with the real natural processes of communication.

We tend to forget that when we say "society", for describing the subject - object of Reality, we are ignoring almost all the world!

In fact Earth is inhabited by millions and millions of diferent kind of societies.

Biosphere is a multisociety. Each species or group of individuals is a  society.

Cybernetics within Ecosystem makes Ecology Science, and viceversa: Cybernetizing a discipline and Ecologizing it is almost the same.

In ecosystem we are able, humans and not humans, of share space and ressources. Human society adquire it category when humans are actually aware of multisocietal Biosphere.

Animal Husbandry is a good example to take us now this sense of mutualisms that shape Life.

Mutualism needs previously the coexistance and convivial of diferent organisms toguether.

And, in the same way, Symbiosis, needs previously of a time of mutualism between diferent organisms.

It is very interesting that the term for FeedBack come from "To eat" or to nurture.

It is a parallel with "Sabor" and "Saber", in spanish, italian... puting in it point our physical biological "pre-cognition" processes, as animal-observers...

What it is here merging is our human belonging to a multisocietal system shaping territories and landscapes.

In these landscapes beyond living organisms you could see, and touch, the transformed material memory of a miriad of organisms which became now Calcareous Rocks.

In many ways these rocks are alive because they have dynamic lives, changing their structure and comosition with time, as in Karsts.

Anyway these rocks are nurturing the next soils, feeding thus plants and other organisms.

At diferent speed all ecosystem is dynamicaly changing, and at a great scale, all Earth-System conform a fluid  changing system.

Second cybernetics share it roots with the historical bases of (participatory) democracy.

Ecclessia means assembly.

The circle of dance is already accepted as the older church or and assembly.

And the talking circle is curiously rescued and used today in modern conferences for a easier and friendly contact with colleagues.

second Cybernetics, as measured by the quality of feedbacks, have in front, "three Promised Lands", to contagiate:

Politics.- The possibilities are infinite, the changes are coming

Mass Media.- The possibilities are infinite, the changes are coming

Universities.- The possibilities are infinite, the changes are coming

Internet (2.0) Do Is the great anarchist Revolution.

Internet 2.0 is a great assembly where all people have their way to talk and participate.

Curiously enough, Corporations, for their success in internet, they have been propelled twards anarchist levels of transparency, that have been demonstrated as the most fluid and easy way of (auto) governing ourselves.
