This paper develops the ethical and political proposal created by the American philosopher Judith Butler from the critical concept livable world. The implicit question into this writing is: who cannot fully inhabit the social world? The first section explains what Butler does mean as a livable life, and also what unlivable life means. In the second, the last problem is studied in terms of language livability. After an ethical exam of the performative theory of language it is shown how, after the failure of repeated linguistic norms, agency appears, and unlivable lives get the capacity for action and can signify in a different way the terms that oppress them. The conclusion shows how Butler’s critical ethics radicalize democracy doing the necessary questions to make the world a more livable place.
