ABSTRACT
This chapter shows that throughout history many non-essentials have organized lives as substitutes of what is really essential. The other part indicates a ‘cohabitation’, thus to be born together, to live with something or somebody. Thus, the action of knowing, the process of learning is a shared activity which gives birth to two human beings participating in the confinement which makes them learn. Every action, situated at any level, be it economical, familial, political, or ontological, has been replaced by a counter-evidence: the separation of theory and practice. Clearly every process of knowledge is at the same time theoretical and practical. One of the essential characteristics of the historical and social reality is the existence of dominant and dominated groups, dominant and dominated nations. The fact that certain social groups dominate other groups, certain individuals dominate other individuals, certain countries dominate others, is related to the question of power.
