MDT is not very much preoccupied with this problem, as extremely many factors exist, associated to the technological implementation of the whole being. This section wanted only to show that the functioning of the internal body is controlled by a technological process brain, which works in the same way as the main brain. The process brain is dedicated to the construction of a reality associated to our internal body, which represents its external reality. ETA 34: The European spirit The theory and the applications are associated mainly to the European cultural space. Europe is a cultural environment where the extensive development of civilization was achieved based on symbolic models, associated or not to image models. Except geometry (created in a space in close communication with the European cultural space), Europeans have created the great fundamental models. We are talking here about Christianity, open sea navigation, the heliocentric model of the Universe, polyphonic music, Newton's Mechanics, Quantum Mechanics and Relativity theory. Let's evaluate the European spirit based on some of these models. The Roman Empire has been created through conquest, but wherever the Romans got, they created efficient organisation structures, which have been in favour of the conquered people too. Thus, Romans have been both conquerors and civilisators. This characteristic in the way of thinking is a permanent feature of Europeans up to our time. Thus, the large colonial empires did not bring colonisation of Europe with slaves. Independent of the injustice to the colonies, when leaving them, they were left in a good or very good general shape, e.g. Hong Kong. Nowadays, the European Union spends a lot of money earned by European work, to civilise Eastern Europe. Europeans created Christianity for Europeans. This is why the Christian religion is tolerant and has reduced tendencies towards fanatism. A significant number of facts show that Europeans have an adventurous spirit (Marco Polo, Columbus, Magellan etc.) The spirit of adventure is associated closely with the desire of knowledge, the search for new ways of evolution, and the need to analyze everything, and never accept an invariant situation. An example exists connected with the heliocentric model of the Universe. From Antiquity, everybody knew that Earth is the center of the Universe. This was proved by direct everyday experience and, at least, implicitly, by the Holy Bible. The scholars of Antiquity have left us precise methods of calculation for eclipses of the Sun and the Moon, and data on the ecliptic, and as a consequence on the position of the Equator and the Tropics. Then, why after year 1500, some Europeans did consider that something was fishy about the geocentric model of the Universe?
