Abstract
From the identity-metamorphosis-emancipation triad (Ciampa, 1987), this article aims to examine the search for sustainability as an intrinsic condition related to self-determination and the autonomy of subjects. It examines the concept of identity in its polysemy by confronting three great narratives: Mead, Ciampa and Ricoeur. This article then focuses on the question of the construction of identities within a society that limits human action by the ambiguity of the frontier man and therefore jeopardizes the sustainability of his emancipation. It finishes with the analysis of the strengthening of social identities where man has, in the construction of his own trajectories, the potentiality of changing himself and the world.
