Professor of Law, University College London.

I would like to thank for all their comments and criticisms the participants of the Cegla Center conference on Community and Property, held January 2-3, 2008, for which this Article was written, and also those who offered their reactions when I subsequently presented it at the University of Exeter and at the University of New South Wales. I must
mention in particular Yitzak Benbaji for his extensive written comments, and Larry Alexander, Martin Krygier, Robert Lamb, Stephen Munzer, David Schorr, and Jeremy Waldron for their very thought-provoking criticisms.
