ABSTRACT
The above has considered arguments to the effect that exclusion is never justifiable. What I want to focus on now are those arguments to the effect that it is sometimes justifiable. There are, here, two distinct categories of argument: the first begins with facts of national or cultural identity, and the second upon the moral rights of individuals. The lines between the two are not sharp; many theorists invoke arguments from both categories. Nevertheless, I want to differentiate them as much as I can. I will begin with the first category; since my own view is best described as falling under the second category, I will spend more time there.
