Not all absence is absence. Often, it is constructed, sustained, and socially legitimized. Social Invisibility offers a philosophical reflection on lives that remain outside the field of recognition — not because they are far, but because they do not conform to what society allows to be seen. Ignored presences, unheard voices, bodies reduced to background noise or silent utility. The work explores the symbolic, political, and affective mechanisms that erase certain subjects, and the quiet gestures that still resist indifference. To see the other, here, is not a moment of empathy — it is an ethical demand.
