ABSTRACT
The built-in justification is a system which allows individuals to explain to themselves their existence and to give them reasons to be content with it. It is like a building whose weight is distributed on walls that are themselves resting on foundations. If a new window is needed, the existing forces must be calculated and then supporting beams must be installed before the wall is opened up. In ancient times myths explained natural and human phenomena in a sufficiently satisfactory way for people to be content with them for thousands of years. In sensitive projects, sometimes the first reaction is to give people time so that they can get used to the new realities. Social forces are released which totally outweigh the original project. The sensitive projects which are a hit, as they say in show business, often succeed through a series of lateral projects which, little by little, lead to the final objective.
