Abstract
The present social division urges to think about humans's competence to live side by side on a peace common world. We assert that an intersubjective psychic process that would operate in intersubjectivity's relationship: human being and being together are created by a dynamics of mutual recognition of consciousnesses (reciprocity phenomenon). “Reference figure» initiate that. This thesis was put to the test in the field of sport. The first study showed that an authentic self-sacrifice by the reference figure, being-next-to, keeps safe from being-together. A second study showed that a consciousness of intersubjectivity of the reference figure allows a start of the reciprocity movement. Finally, a research-action into sportive-mediated workshop showed how a fight for recognition, if the reference figure is “atmospherically good” and is recognized as such, shows how the primitive aggressiveness of a young delinquent perform towards a mutuality of consciousnesses by a oneself-common world ‘s unity creation. All the results allow to conclude that the reciprocity phenomenon releases a passive physical phenomenon (reception) together with an active physical phenomenon (giving, for-giveness).
