Good and Evil

[bennyboy]

Then whatever each person identified as their nature would not have any universal commonalities with everyone else. In that case there is no reason for saying that anyone else is truly human or has human rights.

Supervenient qualities transcend their component parts. A person is more than just a bunch of particles-- a person is also the relationship among those particles.

I would say that the morality of a given society is a complex web of relations between that society's members. It is an order of magnitude more complex, and less concrete, than the mores of the individuals. Human rights may be hard to define, but they are still there, in the way the society as a whole treats its members.
