"Religion gives a knowledge that cannot be proven, so it is not the scientific knowledge in my opinion."
Of course religion is not science. That is why I listed it separately in the first words of the essay. I'm not sure where you are going, but science is not really "proven" either. Hypotheses are either rejected or not rejected. Therefore, an observation may be not rejected by several models.
Religion offers morals for society. The success of religious knowledge is the long-term survival of its adherents. Religion offers hope. Whereas, science understanding offers predictability. Our science is weak on the predictability of social actions. I also offer the idea that if the social structure is weak, then the science doesn't help. Note the African tribes killing each other. The only thing stopping them from using the science of food production is their political instability. A society needs both morals and science.
The idea labeled the "Theory of Everything" is somewhat defined as to the problems it must solve. Is it a misnomer? You betcha. So?
"But the collapse of societies is always ruled by its governors egoism..." and the peoples support of that government. Very often the people and the society allow and even support the government.
Indeed the morality of the individuals that are the components of our reality and that have always to struggle for survival because of the dualistic essence of this reality is THE important factor for the character of our society." Agree. Note the comment on the African tribes above. They are tribes (Diamond's definition) fighting. We know a state (Diamond's definition) is possible. The science to better their position is known but unusable because of the limitations of a tribe structure.
"Any new constitution is a result from a changing mentality...". I disagree if you mean morality. The new constitution of 1789 did not require a different morality - It merely had to solve problems the larger structure was having. But there is an interesting point in this. The US revolution and following constitution was lead by barons - that is educated, rich, business leaders, etc. The French revolution in the same time frame was created by intellectuals and "common people". This is why I noted "baron" not people.
A change in human consciousness is unnecessary. But the change must be lead by practical leaders. This is what is developing. The barons are organizing.
