ABSTRACT
The chapters in this collection are united by a particular interest in the ties that bind together the members of political communities and simultaneously separate them from the remainder of the human race. They are especially concerned with bounded communities, which are a problem for themselves in that they exhibit unease when efforts to protect security and other interests lead to excessive force, cruel and humiliating behaviour, negligence and other ways of infringing moral principles that grant all human beings equal moral standing. They are linked by a specific interest in the relationship between the duties that individuals have to one another as citizens of separate states and the obligations they have to all other persons as members of humanity.
