The goal of this paper is to show that the Kantian correlation beween universalizability and humanity addresses the communitarian critique by resorting to the positive identification between human rights and fundamental rights and to the normative conception of moral persons, irreducible in theirhuman dignity. I argue for what may be termed a transcendental-semantic perspectivism that allows for a more reasonable, sustainable defense of cosmopolitanism than previous accounts of universalist and communitarian models.
