One more thing ...

Michael S.,

I don't know that I've ever met a relativist.  The serious issue, in my judgment, is ethnocentrism.  I've met some ethnocentrists.

On the challenge of negotiating the relationship—sometimes but not always a relationship of tension or even conflict—between “universal” values and “local” values, the essays in Andras Sajo, ed., Human Rights With Modesty:  The Problem of Universalism (2004) & Christopher L. Eisgruber & Andras Sajo, eds., Global Justice and the Bulwarks of Localism (2005) are a good place to start.
