ABSTRACT

From a Christian social ethics perspective, this paper diagnoses the deepening problems of identity absolutization and the collapse of public truth in the post-truth era. It proposes an ethics of inclusion based on ‘transversal identity’. Post-truth signifies an epistemological shift where identity and emotion determine truth, leading to closed, ego-centric homogeneity and the breakdown of the common good. The study first examines Kant’s reason concerning identity, which established a modern fixation on identity, and then explores the potential for relational identity through Deleuze’s philosophy of difference. To complement the normative limits of Deleuze’s philosophy, this paper demonstrates that Welsch’s transversal reason is a third form of rationality capable of harmonizing diversity and universality. Through this approach, identity is redefined as a transversal process rather than a fixed substance, presenting an ethics of inclusion to overcome exclusion in the post-truth era.
