Right—but there are surely also ultimate values.
Those are the ones that are expected to be resistant to change.
Correct. My current claim is that almost all of our moral values are instrumental, and thus subject to change as society evolves. And I find the source of our moral values in an egoism which is made more effective by reciprocity and social convention.
I think that the point is that emergence is in the mind of the observer. If the observer is describing the situation at the particle level, then superconductivity is not there regardless of the size of the collection of particles considered. But, when you describe things at the flowing-electric-fluid level, then superconductivity may emerge.
