The Uncanny Hospitality of Choosing to Share a Planet

How can we share Earth with those with whom we do not even share a world? The answer is crucial to figuring out whether there is any chance for cosmopolitan peace through cultural diversity and the biodiversity of the planet. Inspired by Kant's suggestion that political rights are founded on the limited surface of the earth, and Derrida's suggestion that each singular being is not only a world, but also the world, I attempt to articulate an ethics of sharing the earth even when we do not share a world. This earth ethics is based on our shared cohabitation of our earthly home.
