Evolution has only one goal, the reunion of the physical space with S-Space, which is achieved through the slow transformation of plain matter into information. However, this marriage cannot be done anyhow! It must respect a few conditions, in particular those imposed by a process called "information selection". This one occurs at every level of the evolution towards S-Space and is in fact the actual mechanism behind the famous "natural selection". Following the idea, it can be as well applied to any development of mankind. This process could be described simply like this. Amongst the multiplication and the variation of possibilities, the selected solution is the one that contains the most coherent information according to a given context. It is not necessary the best solution in the absolute but it is the most accurate in a certain technical, social or natural environment. It is the most acceptable solution according to the perceived reality of a situation.

This means that the process of evolution has indeed three steps:

1. The Return Force creates an attraction field that tends to increase the quantity and quality of information, the degree of complexity and coherence contained in the living or non-living matter.
2. Random variations around a certain state of information (due to the law of entropy that opposes itself to the Return Force by producing more chaos) or human’s imagination multiply the number of possibilities.
3. A process of selection filters the information to keep preferably the most coherent one according to a given state of knowledge, consciousness, natural environment or any other restricting context.

A coherent information achieves a higher degree of interpenetration with S-State and that’s the reason why it is selected. This principle has a major importance in the mechanism of evolution. It is the condition that determines how matter must be organised to be able to combine itself with S-State. Their original separation created a huge potential field and since then it decreases every time a step is accomplished towards their reunification. It is in fact the same phenomenon that occurs with the gravitation field (which also results from the Return Force, as we have seen). An object that can freely move towards the ground will be stable when it reaches a point of minimum potential energy. This will not be an absolute minimum, but the lowest point accessible under those particular circumstances. In the case of a river this would be done gradually, step by step, following the lowest curves of the ground until to reach the faraway ocean. This image suits perfectly to the process of evolution. Every selection, every increase of the information’s coherence, every step down of the river is a temporary choice that depends of the possibilities and restrictions of the local context. New discoveries, random variations or modifications of the external conditions will soon or later brake this relative equilibrium and open ways that will lead even closer to S-Space.

Thus, life is joining the physical space and S-Space by allowing the transformation of plain matter into a more immaterial state, information. But not any information is acceptable! A process of selection is necessary to keep only the most coherent one. This "quest for the truth" is the only way to find a path that converges and possibly leads closer to S-State. At the highest level this is achieved through the opening and widening of consciousness. That’s why, to complete the evolution towards S-Space, matter has indeed to become

A TRUE IMAGE OF THE REALITY.
