This new symbolic model was created based on a new Geometry and some new principles. Together with Quantum Mechanics, the Theory of the Relativity speeds up the evolution of society.
1914 BC: The First World War (The Great War)
1917 BC: Communism in Russia Communism is an ideology. It is based on an image model translated to some short-range symbolic models.
The main problem of the Russian society of that time was a huge dispersion between the level of understanding of the external reality from one person to another. Even worse, the level was low compared to Western Europe. Communism was only a fast solution to the problem, at least on short-range. Of course, an invariant ideology could be useful only on short-range. As we know, the communist system crashed due to the lack of economic efficiency, but the basic cause is associated to its invariance.
The problem of the dispersion between individuals, countries or cultural zones continues to be a big problem of human society. The problem has a tendency to get worse and worse.
1928 BC: Walt Disney As the evolution to symbolic models speeded up, the brain also increased the conceptualization level of the image models. The cartoons are based on such concept image models. Everybody (including childrens) easily understands them.
1938: World War 2
Both world wars starting in Europe occured in a very complex set of known and unknown factors. MDT can be used to evaluate the problem.
Since Napoleon, there was a general tendency to war in Europe. MDT says that there must be a war-associated ZAM, which must be assimilated and accepted by the majority of the population. Also, the consciousness level has to be high enough to think that the war will solve all the problems, but not high enough to understand that this is not true.
One example of such a ZAM could be "we have better weapons" or "we are powerful enough to win". Of course, the attacked people have a ZAM as "we must defend our country". It is possible that such action models create conditions for a war. But, such models, even if they are assimilated and accepted by the population, are not enough to start a war. There must be also a big enough number of high-ranking persons to plan such a war, and a series of technical conditions.
