Round 1
JshwtfFOR
Objective morality does not require a God. We can ground moral reasoning in human well-being, equal moral consideration, reason, empathy, and principles that apply consistently to everyone. Saying “God commands it” doesn't solve the problem either, because we still have to ask whether something is good because God commands it, or whether God commands it because it is good.
CalmStormAGAINST
The practical consequence of my view is simple: if God doesn't exist, when two societies disagree about something like slavery or genocide, you're left with competing human preferences and power. You can say cruelty is wrong because it harms flourishing, but that just assumes flourishing is the standard. Why is flourishing objectively good? Because we prefer it? That's not objective. The secular moral realist can assert moral truths are brute facts, but that's a label, not an explanation. A law needs a lawgiver, or at least a standard beyond human minds. Without that, morality is a human invention we enforce. It can be useful, even admirable, but not objective. So the possibility you're defending is really a hope, not a foundation. I'm not saying atheists can't be good. I'm saying they can't make their goodness objectively binding. That's the cost.
Round 2
JshwtfFOR
A law needs a lawgiver, but morality is not literally a law, so that analogy already assumes what it needs to prove. Saying God grounds morality also doesn't explain why God's commands are morally binding unless goodness is independent of God or “good” simply means whatever God commands. And if God is the standard because He is powerful enough to impose His will, that's authority, not objective moral justification. Human disagreement doesn't make morality subjective any more than disagreement about mathematics makes mathematical truths subjective.
CalmStormAGAINST
Jshwtf's Euthyphro point is the strongest thing on your side, but it cuts both ways. If God's nature is the standard, then commands aren't arbitrary; they reflect what goodness actually is. The dilemma only bites a voluntarist God, not a morally perfect one.
But I'd say your positive case still has a hole. You say ground morality in well-being and equal consideration. Fine. Why are those objectively binding? If someone says, "I only care about my own well-being and my group's," you can call him inconsistent or cruel, but you can't show he's objectively wrong without smuggling in the very standard you're trying to prove. Reason and empathy are human capacities, not external laws. They tell us what we prefer or what follows from premises we already accepted. That's coherence, not objectivity. So the possibility you're defending still looks like a hope wearing a firm voice.
Round 3
JshwtfFOR
You are right that merely asserting “well-being is good” would not establish objectivity. But the same problem applies to God: saying God's nature is objectively good does not explain why His nature is good; it simply makes goodness identical to that nature. The deeper point is that objective truth does not require an external lawgiver. Mathematics has no cosmic legislator, yet mathematical truths can still be objective. Likewise, moral realism can hold that some moral propositions are true independently of what humans or gods happen to prefer.
And if you argue that God is the foundation because He is necessarily good, you have already accepted that goodness is not grounded merely in a command. You are appealing to a standard of goodness to explain why God's nature is good.
CalmStormAGAINST
Take a slaveholder in the 1800s who sincerely thought owning people was fine and good for his society. If no God exists, what makes him objectively wrong? You can cite well-being and equal consideration, but he can just answer: I don't value their well-being. Your math analogy fails because numbers don't depend on anyone caring; morality does. A truth that only binds people who already accept your premise isn't objective. So the possibility you're defending still rests on a shared human preference, not a standard above us. That's a consensus, not a foundation.
