Is the future of the sociology, as Monique Hirshhorn in a text published in 2000 imagines it, in the introduction of a “initiative clearly phenomenological”, allowing “not to reduce the ‘subject’ to the rational actor” and in a new questioning “on the social construction of the self” and “on the modes of elaboration of the identity”? Either it will be a question of turning rather to a sociology of the relation to which referred Laflamme in 1995, Emirbayer in 1997 or Donati in 2004, within networks as in the structural analysis or in the construction of trialectiques models proposed by Laflamme for whom only the relation, the communication, being the social and the human, is the social and the human? This question is at the heart of this article which tries to show that the contemporary evolution of sociology goes from a sociology of “substances” (“objects” or “subjects”) towards a sociology of the relation.
