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 i… - J. L. Mackie

Notoriously, there are disputed territories — for example, border areas and regions occupied by groups which are not independent nations, but many of whose members wish that they were. Again, there are territories like that which used to be called Palestine; here the principles which in the case of Norway point univocally to one national group as that to which the area belongs diverge, some supporting the claims of the Israelis and others the claims of the Palestinian Arabs. Cyprus and Northern Ireland are two other obvious examples of conflicting prima facie rights of distinguishable national groups. In such cases the appeal, by both parties to a dispute, to supposedly absolute rights is disastrous. It reduces the readiness to negotiate and compromise, and it seems to justify any atrocities against the enemy, and any resulting losses and suffering for one's own side, that are needed to vindicate those rights.

Mutual toleration might be easier to achieve if groups could realize that the ideals which determine their moralities in the broad sense are just that, the ideals of those who adhere to them, not objective values which impose requirements on all alike.

The abandonment of a belief in objective values can cause...a decay of subjective concern and sense of purpose. That it does so is evidence that...people...have been tending to objectify their concerns and purposes, have been giving them a fictitious external authority. A claim to objectivity has been so strongly associated with their subjective concerns and purposes that the collapse of the former seems to undermine the latter as well.
