Our article came divided into three instants. We have devoted its principle to considering the lexical connotations of the concept of recognition and its philosophical extensions as it occurred in both Descartes' and Kant's approaches in the form of "knowledge and knowing". In the second instant, we discussed the elements of the philosophical recognition that is embodied in a human self capable of remembering the promise and the gift. The process culminated in a third instant in which the need for recognition as a symbolic act that entrenches the value and dignity of the self, secures confidence in itself, enables it to be open on the other while taking into account his right to exercise his identity under the principle of the priority of difference over similarity and equivalence.
