@joefromchicago,
Where would you be without straw men to prop up your feeble arguments? I don't think that universal agreement is a necessary condition for morality. I have said nothing remotely like that. What i say, and have said many times, is that objective, absolute morality cannot exist; and i have acknowledged that if someone can provide unquestionable evidence of the authority for universal, absolute morality, then they will have established that it exists. I don't see you doing that, i just see you trying to pick apart the arguments of those who have dared to disagree with you.
The definition of morality from the Stanford Encyclopedia of Philsophy, for example, does not necessarily specify an absolute, universal standard:
The term “morality” can be used either
1. descriptively to refer to some codes of conduct put forward by a society or,
some other group, such as a religion, or
2. accepted by an individual for her own behavior or
3. normatively to refer to a code of conduct that, given specified conditions, would be put forward by all rational persons.
Of course, the article goes on to discuss what might be the specified conditions. The first two definitions are pretty straight forward, and refer to a conception of morality, not to some independently existing moral absolute. The third definition is fraught with the specified conditions.
But i'll ask you two questions, and then we can play your favorite game of who asked whom first, and who has to answer before the other will deign to answer. If you assert that there is an absolute morality, what is the source, the authority for that absolute morality? How do you know that to be true?
People who rant on about objective, absolute morality speak as though it were some noumena existing freely in the cosmos. I am unconvinced, and have yet to see any plausible argument for such a claim.
