There are no objective values. - J. L. Mackie

We want people to see it as not only legitimate but right and proper that they should pursue what they see as their own well-being.

To say that someone has a right, of whatever sort, is to speak either of or within some legal or moral system: our rejection of objective values carries with it the denial that there are any self-subsistent rights.

Does the right of a nation as it is at present to its territory include the right to forbid or to limit immigration, or to deny full citizenship to immigrants and even to the locally born children of immigrants? Obviously this raises the question just what is to count over time as the same nation.
