I believe the basic problem with trying to track objective morality is that people tend to search the objective root in individuals rather than populations. That is a bit like studying the objective properties of water by studying a molecule. You can't. Within any population there exist a great variation of individuals who when added up form a deterministic and predictable pattern.
That's why I want to discard the concept when thinking about this. Morality has been irrevocably affected by things like religion or emotionally laden beliefs about what's right or wrong. There's just no way the average person will ever consider the ultimate pragmatist or "benefactor" a morally just person.
I'm not saying it's an easy task to ascertain what's beneficial or what's harmful, but I'm saying that if we leave aside the emotional or religious aspects, it's slightly less hard.
I just don't want to use words like good, evil, or ethical - because they're simply too messy to work with. "Cold" concepts like benefit and harm are easier when wanting to reach an agreement. I suppose you could say I don't want people to manipulate themselves by old-fashioned images - as our tradition is to let emotions rule. This pretty much always results in short-sighted conclusions.
We don't want to talk about objective truths either, because that's definitely impossible - at least so far. Which is why we will not tell ourselves that we're right - ever - as long as we're not omniscient.
What we should do, is work towards an agreement about things like basic necessities and the means by which we can achieve the most reasonable division of resources. I believe technology is one thing we have to aid us here, that we didn't have 30-40 years ago. We have the means to fully automate a lot of processes that would otherwise need to be carried out by a labor force. This was always detrimental to a fair and even society - because our nature has never been to work when we don't have to. That's something society has placed on us as a standard, and the vast majority suffer for it, every single day.
Übereil, who finds it interesting that all moral relativists he's come across have also(unconciously) been utilitalists, even though it's it's natural to him that moral relativism leads to moral nihilism (IE not caring about right and wrong, since it doesn't exist/is meaningless)
I strongly dislike labels because they cloud and simplify complex issues. If you want to call me morally relativistic and utilitarian for the sake of your own comprehension, then be my guest, but I'd like to suggest that you'll never get the complete picture in that way - assuming you even want that.
But if you think I'm not aware of the seeming applicability of those labels, I'd have to say you're very wrong
