Abstract
The notion of vulnerability is one of the most original theoretical underpinnings of Martha Nussbaum’s philosophical project. Inspired by Aristotle and by a reappraisal of Greek tragedy, the American philosopher recovers an important perspective for contemporary ethical and political reflection: our continuous exposure to unexpected, changing or contingent situations of fortune that can considerably affect our search for a good life, and altruistic emotions as a response to that essential fragility that shapes us. This article offers a reconstruction of the idea of a vulnerable moral agent as a key insight that allows Nussbaum to articulate a more pregnant conception of social justice, human dignity, and quality of life, incorporating intuitions about the nurturing and refinement of certain moral emotions which are relevant to counteract our all too frequent failure to see the “other different” as fully human.
