Is it true that there is no absolute morality?

[bennyboy]

Best actions suggest a moral fact or opinion...but are not, themselves, moral facts or opinions.  They're, as you explained, a way to achieve parity with whatever you consider to -be- the moral fact of the matter.  In any case, it sounds like you're completely sold on the idea of objective morality.  

Only this particularly unpragmatic and hypothetical version. In my actual daily life, I pretty much try not to be a dick-- unless I think someone has it coming. Much less enlightened.

But talking about this stuff makes me consider my thought processes and behavior a little more, so that's something. . .

Transcending instinct and opinion in search of the greater good.  Whatever underlies "the greater good" would be the moral fact of the matter, if there were any.  What moral opinions or instincts do you think correlate to the greater good, if any...or do we need a whole new set?

Unless there's an absolute goal at the end of time, which is useless to us as living humans anyway, then the moral goals will be arbitrary to some degree, though based on the interaction between instinct and environment-- I don't want to discuss whether those are better called subjective or objective, but in the end it doesn't matter to the kind of moral facts we're talking about where the moral goals come from-- in other words, even if the moral goals (one's sense of what a more just world would look like or whatever) are subjective, the best behavior for those goals would still be objective facts out there in the ether somewhere.

 Also, do we need to transcend opinion or instinct if/when that opinion or instinct already correlates with the greater good?

We can't know what represents the greatest good, but with some careful consideration, we might discard at least some of those behaviors which seem not to; for the most part, I think we'd all agree that reigning in the emotions is likely to lead to better decision-making. This idea, "Whatever I do, there is probably a better way that I might discover through a more careful consideration," basically informs subjective morality with that hypothetical objective-- perhaps something like the knowledge of death being able to add some urgency to our will to seize the day. . . or how the belief that the brain is a deterministic machine can lead to more sympathy to those whose machines work differently than our own.
