Migrations driven by ethnic, religious, and other forms of social conflict have been common in the past quartercentury, and have in Africa led many to seek refuge and to expect hospitality abroad. This leads to a concern for pluralist ethics, for many receiving refuge abroad expect that they will be able to live by their thoughts and beliefs, creating enclaves of cultural difference. But difference exists in all communities: cultural homogeneity does not exist except in the conservative imagination. Nevertheless, a sameness ? the sameness of the value of every person ? remains within this plurality. The sameness is conceived in distinct ways in the Natural Law tradition that yields liberalism, in the Golden Rule, in Kant's categorical imperative, and in the Luo culture of Eastern Africa. The Luo precept Luoro remb dhano (?restraint from letting human blood?) is compared with these other ethical cosmopolitan wellsprings in this essay.
