But here is the point then. On what grounds do we hold people accountable for doing "bad", "evil", or "wrong"?
Usually on the grounds that we feel they harm us and our society. Actual tangible grounds that is. Not blind obedience to declarations of "Good" and "Evil" from some "revealed" source of "objective" morality.
I am saying that by your way of thinking that all acts are amoral.
Only because you have gone ahead and defined them that way. Obviously if subjective morality does not qualify under your definition of morality (even though value satatements on right and wrong are made) and if there is no objective morality, then there is nothing left to fall under your definition of morality so it doesn't exist. You are playing word games.
And if they are amoral, then we have no more grounds for punishing a person who kills than a bear who kills. We might do it because we fear the person or bear will do it again, because we don't trust them or are uncomfortable around them, or simply out of a sense of our personal revenge.
Or for any number of other moral bases, such as self preservation, empathy with the victim, etc. By the way, it is interesting that you gave the bear a moral excuse for doing what it did (protecting its young). Why not use the example of a bear who kills for the sheer joy of it? Or would you find that a bit morally repugnant? Sure we can rationalize that the bear is just a mindless killing machine (maybe it is?) but don't you instinctively still feel a sense of injustice when you see it mauling random helpless toddlers passing by? That'd be your empathy kicking in, and it is a big part of what forms your subjective sense of morality.
Certainly we hold human beings to a higher standard than animals, but isn't that because we are human beings ourselves and relate to them better, and because we know for sure that humans are thinking beings who could and should know better than to behave in such a way?
Just because you label it morality doesn't mean it is about morality.
And just because you relabel it as excluded from morality doesn't make that so either.
And subjective morality is a worthless way to run a planet.
It is all we have.
And it works a lot better when we realize that instead of pointing to some "revealed" and "objective" morality that may scream to us peronally as unjust. If you strangle your internal feelings of right and wrong and replace them with obedience to some external code, what do you think it bound to eventually happen? Something rather awful, no? Crusades, inquisitions, witch trials, gentical mutilation, the list goes on and on. Things any healthy person's sense of empathy would lead them to conclude is wrong, but "objective" morality tells them is righteous. Is that any way to run a planet? I think history has shown it isn't.
But I don't understand why you make these decisions in your amoral world.
Because a lack of objectivity in moral judgments doesn't make questions of right and wrong magically disappear. We still have these issues to address and we do so address them.
Then I repeat. If there is only subjective morality, there is no true basis for calling anything a moral good or a moral evil.
Only if you define terms as you have done.
And thus no reason to reward a moral good or punish a moral evil, except for how it impacts me personally, of for some alturistic people, how we see it impacting society.
We punish certain acts because we judge them dangerous to our society's ideals. We see that they will hurt people or threaten our way of life so we deem them wrong and we outlaw them. Conversely, we see that charity helps those we can relate to (fellow humans) and so we call it good.
As I have repeatedly noted, absent objective morality our findings of good and bad are not arbitrary. They are based on the experiences we have, our DNA, and our empathic sense (based on self preservation and idenfication) These bases of what forms our moral sense can be modified by our culture and our programming (be it religious or political), but the bases remain.
On the other hand, if we could show that they were right about their being a source of objective morailty, but that they were wrong about their understanding of what that source was seeking in the way of behavior, then we might have a reason to stop them
I find this truly mind blowing. Are you telling me that you need some external "source of morality" to motivate you from stopping men from bashing the heads of babies against rocks? You otherwise feel no "reason to stop them"? Have you no sense of empathy?
No, absent a belief in objective moraily, we have no right to say that the act is in reality horrible.
Yes we do. I just did.
Because absent an objective (i.e. existing) morailty, morality does not exist.
Now, who is redefining morality?
If you insist on redefining morality for yourself, why should I not do the same?
I am speaking of obedience to a code of behaviour placed upon you from outside yourself, that your own internal sense of right and wrong fundamentally diasgrees with.
Would you really call that "moral?"
It would mean that should this code tell you theft and murder are virtues and kindness a vice, you'd have to call that just and right. This is the kind of mentality that leads to the attrocities I noted above, such as flying planes into buildings or burning witches at the stake.
