@joefromchicago,
Joe,
Morality is clearly a human trait-- almost every human has a sense of morality, the same as almost every every human has a language and a sense of caring for their kids. I have never said that "morality" isn't real.
I am challenging the idea of "absolute morality". My belief is that the same way that, although every human culture has language, the specifics of that language vary from culture to culture. There is no better language or worse language-- even though each person has their own view of language and sees the other languages as foreign.
My claim is that our ideas about morality are specific to our culture (and our upbringing).
The problem is when two different cultures disagree about what is moral or immoral, there is no way to judge between them-- you are always going to make a judgement based on your cultural understanding which is not better then the other persons cultural understanding outside of your culture.
So my thesis is that there is no absolute morality. My main argument is that
there is nothing in the Universe (other then our subjective opinions based on our culture and upbringing) on which to base such an absolute morality.
You could very disprove this by offering up a way to judge two different ideas about morality in a way that didn't depend on the assumption of the unprovable assertions of one culture.
You could very easily disprove this if you could offer an objective, non-culture specific way to judge between two differing views on morality.
