Communist paranoia has slowed down some nations to understand basic concepts as "economic efficiency". Communist leaders have understood this problem, but Communist ideology, as any ideology, cannot be modified. Any change of any ideology will distroy it. The apparent reason why the Communist system crashed was a very low economic efficiency. The basic reason was the increase of the level of understanding of the external reality based on symbolic models by the population. 1979...1994: The fundamentalist Iran, Idi Amin in Uganda, famine in Etiopia, Iran-Irak war, famine in Somalia, war in Rwanda. There are some nations, which cannot evolve due to internal or external factors. A slowing down of the evolution seems to be a general tendency in an important fraction of the world. A typical situation was in Somalia. The facts are: 1. In Somalia was famine. Many died. 2. Western countries (USA included) brought them food. 3. When they obtained enough food, they attacked the US troops. 4. USA left Somalia very fast. 5. Western countries changed their basic principle "life is the supreme value" to a new concept as "we do not help those who do not help themselves too". The first consequence of this change was ignoring the situation from Rwanda. 1993: Terrorist attack on WTC in New York City 2001: Another devastating terrorist attack on WTC (passenger airplanes crashed into WTC). Individuals, groups or cultural zones where the evolution based on symbolic models is blocked, generate terrorism. In such a situation, fundamentalist action is expected. That is, people turn back to image models. As we know, it is not possible to know the importance of an element or a relation, on an image model. Thus, a person based on image models only, has a tendency for paranoia. The logical arguments are not taken into account, because the logic is associated with symbolic models only. On the other hand, some important cultural zones are speeding up their advance based on symbolic models. They gain more and more power due to this. This is the overall situation now. Abstract: the evolution of the brain means the increased power of the symbolic models. The main steps are: 1. Spoken language (about 140 thousands of years ago) 2. Phonetic writing (3700 to 2900 years ago) 3. Euclid's Geometry (2300 years ago) 4. Newton Mechanics (340 years ago) 5. Quantum Mechanics (100 years ago) 6. Some cultural zone speed up their evolution based on symbolic models, but in other zones there is a tendency to turn back to image models (fundamentalist tendency). Some fundamentalist tendencies occur in symbolic countries too. ETA 18: The organization of the human society Faced with external reality, any individual builds and operates some models to predict the evolution of the external reality. The majority of the population is based on image models. One of the organization principles of the human society is: The majority is seldom right.
