In his elegant essay on the tension between a singular global ethic and global ethics in the plural, Michael Ignatieff invites us to “think harder about the conflicts of principle between them.” He is certainly right that harder thinking is needed: advocates of both versions of a global ethic sometimes seem locked into mutual self-righteousness. What we might call singular, or universal, ethicists often accuse pluralists of parochial atavism, while the partisans of plural, usually national, ethics think that the universalists are naive at best, arrogant at worst. Both are utterly convinced that they are right.
