 Cosmopolitan right is an important component of perpetual peace. Interaction among the peoples of the world, Kant notes, has increased in recent times. Now “a violation of right on one place of the earth is felt in all” as peoples depend upon one another and know about one another more and more (8:360). Violations of cosmopolitan right would make more difficult the trust and cooperation necessary for perpetual peace among states. And for Kant, perpetual peace is the “highest political good” (6:355).
