In the lead essay of this symposium, Michael Ignatieff offers a characteristic blend of philosophical acuteness and political good sense on a topic that, we can all agree, is central to many of the most important questions on the contemporary political and international agenda. His analysis is prescient, challenging, and deserves pondering at some length; thus, in this short response I cannot deal with it in anything like the detail it deserves. But the enforced brevity is perhaps an advantage as well, in that it forces me to concentrate on where I differ from Ignatieff and on my own sense of what we might imply when we use such a term as “a global ethic.”
