This dissertation proposes a reading of the specificity of the social tie in the present time, as well as proposes a way where, from this tie, a contemporary politics could be decanted. For this seam, a reading by sociologist Zygmunt Bauman provides reading beacons for delimiting the current state of the social tie. Next, some of Freud s perspectives on the social and modes of group organization, especially as to the place they give to the leader, are opposed to Bauman s description. Jorge Alemán and Ernesto Laclau bring elements for the application of concepts developed by Jacques Lacan from Freud s work to the present political moment, especially in what concerns his conceptions of common solitude, empty signifier and institute act. Finally, the Lacanian concepts of the Borromean node and sinthome are examined with the objective of locating in which the concepts of Alemán and Laclau are supported in the teaching of Lacan. Thus, our dissertation is tied, proposing some orientation within the demarcated field.
