PragerFU: God and Suffering, Part II - misterdeity
This is how dictionary.com defines intersubjective. For some reason, it didn't recognise intersubjectivity:
adjective Philosophy.
comprehensible to, relating to, or used by a number of persons, as a concept or language.
My guess is the definintions of good and bad things are intersubjective and that might be as close as we can get to objectivity.
Ought to Post that in "Uncommon Words..." Group. & I think I agree with you on this. Most of us have a common core of shared basic values, even if they are not truly "objective". We have to exist & interact in a society so our culture helps shape those values we hold in common, & is the reason why they can shift & change over time.
