Assuming that is a Universal for human nature...(andI do not grant that).
What? I don't understand this statement. Are you saying there is not a universal human nature? That "humanity" or "human being" has no consistent definition?
*sigh*
No. That's not what I'm saying. I feel like you have a cursory understanding of this topic and the arguments used, but, are rather new to the conversation.
I am saying instead that the Universal thriving of human beings is not a uniform and universal desire of all persons.
Some would rather it not be case, and would be happier and more fulfilled if humans did not universally thrive.
There are Psychopaths in the Universe. They do not regard universal human thriving or happiness to be something which they consider morally desirable per se. There are some who are sadistic to an extreme and find no joy in human happiness. There are some who are simply so irretrievably misguided that they have a genuinely "moral" belief that they loathe humanity and either wish it in large part, or even entirely destroyed.
Here's the thing, in an atheistic schema that is neither right nor wrong in a truly moral sense. Some people are merely different from even the vast majority.
I am saying that your (I find it naive) assumption that the Universal thriving of humans is Universally the greatest desire of humanity is provably false. Since it is not a Universal given, than it does not have the force of an objective moral truth, but, merely a subjective moral truth.
Or that human beings can find true and ultimate happiness in different things?
No, I am saying that atheists have no grounds for insisting that your assumption of a universal desire for human happiness is shared by all, and that atheists can only think that or believe that
subjectively....
If so, then you would be a moral relativist.
I am not.
I am telling you that an atheist (even though they do not tend to be moral relativists) have no good objective reason not to be. If they were consistent within their world-view, they
would be moral relativists. If I embraced atheism I would be forced to accept Moral Relativism in order to remain intellectually consistent and honest with myself.
Occasionally watching a good (older) episode of Star-Trek will help you understand how, in an atheistic framework, objective Universal moral truths are hard (if not impossible) to assume. They delve into such issues. Or, rather, they did when it was worth watching (like years ago).
This is because from its inception Star Trek always assumes an atheistic worldview. Its creator assumed an atheistic worldview.
I remember a particular episode wherein our intrepid heroes encountered an alien lifeform which practiced euthanasia at a certain predetermined age in order to maximize resources for their offspring who were obviously younger and more productive (or assumed to be)....The humans hated it, and balked at the practice but their "Prime Directive" battled against interfering with it.....
It's instructive actually.

Are you denying the existence of universals?
I am saying you helping yourself to that universal truth
ab initio (as a Christian you can do that)...but, you want to permit the atheist to do the same.
The atheist has no grounds for helping themselves to that.
Which is why their morality is not therefore objective in nature but rather subject.
What I am saying is:
I believe the argument will fail to be either:
1.) Truly objective
i.e.
The atheist has to help themselves to a moral belief which cannot be enforceable without wrongly violating the rights of others and is therefore subjective in nature.
2.) If objective, truly a moral fact and not an incidental one.
i.e.
Mathematical truths may be universal, and the atheist is welcome to help themselves to them as truths,
but they are not then moral truths.
Then that again would concede to my argument - you are a moral relativist with regard to creation.
I concede nothing.
You cannot derive and ought from an is.
Not true. I have already responded to this. Go back and read what I wrote.
You cannot, and I think you have failed (so far to address it sufficiently)
Some (many in fact) genuinely believe a "moral" truth that human populations should be greatly reduced to the point of nearly proposing mass execution/death.
And they are objectively wrong
Given an atheist world-view, they cannot be objectively wrong.
They could be wrong about incidental facts like not understanding that the sum of 2 and 2 is 4, but, they cannot be objectively proven wrong about their morality.
.Just like people who think the earth is flat.
You used an incidental and
non-moral fact to try to demonstrate that (given atheism) they can assume moral facts.
That example demonstrates what I am saying to you.
You are deriving an "ought" from an "is".
Population reduction would not be in accordance with the life and happiness of all human beings.
Maybe, but who says all humans
SHOULD be happy?
That people disagree on what truth is does not mean there is not truth.
True:
Some people are atheists.
Most atheists and some Christians believe that atheism can truly account for objective moral truths.
But, they cannot.
And that is only morally relevant if God's purpose/design for mankind is that this occurs and he has so ordered the Universe (or issued commands as provided in Divine Command Theory) that we are compelled to seek after that same goal.
Which is it? Are moral truths located in His creation or his commands? That is the whole debate right there. If morality is located in creation, then I win. If only in commands, then you win.
It's in both.....perhaps more than both. Actually, I would say it's really
grounded in God's nature, and his creation is a reflection of his nature....
It is not an "either/or"
They are (or at least can be, and I think they are) complimentary.
From the moment you began this conversation with your initial O.P. you made the assumption that anyone who disagreed with you must adhere to "Divine Command Theory". This has failed you, I think. That is not a good assumption. Obviously, you have a certain familiarity with this topic and arguments used in it, but, this assumption is wrong. Divine Command Theory while respectable and possessed of much truth is, I think, wholly insufficient as an explanation of objective morality.
God's purpose for mankind could have nothing whatsoever to do with human happiness and it would still bear the burden of objective moral truth.
Okay, so if God says, "Obey my command to wear a blue shirt next Tuesday. Your reward for doing so is that you, your family, and all of humanity will be tortured in utter misery into the everlasting. If you disobey me, you will be punished with everlasting life and happiness and joy for you, your family, and all of humanity." Are you morally obligated to obey God and wear a blue shirt next Tuesday? Would you?
O.k. I'll bite:
I was thinking of angelic beings when I wrote that.
It would seem to me that God seems to have little or no particular concern for them in the same way he does his "image-bearers" (which they are not).
Obviously, he doesn't torture them, and would be evil to randomly cause them unneccessary pain or torment for no reason. And yet they are clearly intelligent, powerful, and even possessed of some measure of freedom of will.
However, they are nonetheless a completely different sort of being altogether.
Morally, I do not think that their thriving or happiness is to be regarded as the goal/purpose of their existence. Their purpose is
wholly different than that of mankind's.
They serve him. That is all. That is neither cruel nor wrong, and they don't simply suffer in this capacity, but their "happiness" seems if anything...vaguely irrelevant.
God's purpose then, for mankind,
could have been wholly different (as it is with angels) and it would not be "wrong" of God to design them/us that way. It happens to be true that God has made us differently. Universal thriving and human happiness
CAN BE accounted for as an objective moral truth in THEISM. God had
purpose for us, and that was his design and the foundation of insisting that we conform to the morality which will augment that design/purpose.
This is not "Divine Command Theory"...It's more like "Divine Purpose and Design" theory.
Thus, as I said earlier....atheism cannot simply help itself to something like "purpose" for mankind
ab initio. Don't grant them verbiage like that. Given atheism...humanity, its existence, and its tendencies wants/desires are mere rote facts (like 2+2=4)
They are not moral facts...
They are a descriptor of how humans happen to be phenomenologically.
It's an "is" in atheism not an "ought".
I do appreciate your willingness to take up this debate and stand your ground in it. It has been fruitful engaging and educational thus far.
Thank you for your willingness to debate a meaningful topic!
