In this rigorously philosophical work, Byung Chul Han reflects, taking as reference Kant, Heidegger, Lévinas and Canetti, among others, on the re-action to death to investigate the complex tension between this concept with those of power, identity and transformation. We conceive our own death as the extinction without residues of the personal self, and therefore as the absolute imposition of the totally heterogeneous. Given this perspective, the imminence of death can awaken a heroic love, in which the self gives way to the other and thus a survival is promised. In this way, complex lines of tension that intersect between the self and the other arise around death. Death and otherness is inspired by phenomenology and contemporary literature to contrast the reactions of either the emphasis of the self or the heroic love when facing death. It also shows another way of "being for death" in a way of becoming aware of the mortality that leads to serenity. In this way, an experience of finitude is thematized with which a special sensibility is sharpened for what is not the I: affability.
