Can objective morality exist without a transcendental lawgiver?

Welcome to the debate arena! Today's topic: "Can objective morality exist without a transcendental lawgiver?". Your opponent's style: Richard Dawkins

There can be no objective morality without a transcendental law-giver. I saw this because, without something outside of man that defines morality, it becomes a nonexistent idea. It is no more real than a unicorn or Manbearpig. It becomes nothing more than a fiction, which a given person or society writes for itself. Because it is a fiction, there is no objective metric by which one society's or an individual's morality can be judged as superior to another. For example, one cannot say that the highest morality is simply to create the greatest good for the most people, and that is our objective metric, because that relies on some outside concept of good, and the maximization there of.

You're smuggling in the very assumption you need to prove. You claim morality without a transcendental source becomes "fiction" like unicorns, but fiction and non-existence aren't identical. Mathematical truths exist objectively without a lawgiver, yet they're abstract. Why couldn't moral facts work the same way? Your utilitarianism example backfires too. You say "greatest good" requires an outside source, but you haven't shown why objective moral properties can't supervene on natural facts about suffering and flourishing. You've just asserted that objectivity requires transcendence. That's the debate, not the premise. What makes a fact's objectivity dependent on being decreed rather than discovered?

You're equivocating on what "objective" even means. Math works the way it does because numbers exist as abstract objects independent of human minds or decree—they're discovered, not invented. But here's the problem with your analogy: mathematical truths don't tell us what we *ought* to do. They describe what *is*. You cannot get an ought from an is. Morality is fundamentally prescriptive. It makes demands on us. "You should not torture children" isn't just a fact about suffering patterns like "2+2=4" is a fact about quantities. It's a command. And commands require a commander. Without something transcendent to ground that "should," your "objective moral properties supervening on natural facts" is just dressed-up relativism. You're saying morality reduces to preferences about suffering and flourishing, but whose preferences? Mine differ from yours. Call it "supervenience" if you want—that's just philosophical window dressing on the same problem: without a source outside human preference, you have no grounds to say my moral conclusions are wrong and yours are right. You've simply renamed the problem. This is why I said that even if you wanted to attempt to use a mathematical metric to define morality, such as creating the greatest good for the greatest number of people, it would still fall apart for lack of an ability to define what that good is. Many cultures have disagreed in many ways on what a good is, and what a bad is. Many cultures still disagree to this very day. The same cannot be said in the same general sense about something like mathamatics.

You're right that "ought" differs from "is," but you've misread my position. I'm not reducing morality to preferences—I'm grounding it in mind-independent facts about conscious experience. Pain is objectively bad for the being experiencing it, full stop. That's not preference, it's structure. Your disagreement with me about what's good doesn't prove there's no fact of the matter, any more than ancient disagreement about astronomy proved the Earth was flat. Cultural variance proves humans are confused, not that truth doesn't exist. And your transcendental lawgiver solves nothing: if God commands "torture children," is it good because He commands it, or does He command it because it's good? You've just kicked the problem upstairs.

You're smuggling in the very teleology you need to prove. Yes, pain exists as a brute fact. But "pain is bad" isn't a fact about pain—it's a *value claim* about pain. You're confusing ontology with axiology. A rock doesn't experience pain as bad because rocks don't experience. A masochist experiences pain and judges it *good*. The structure of conscious experience doesn't dictate the valence we assign to it. You keep saying cultural disagreement proves confusion, not relativism—but that's exactly backwards. If objective moral facts existed like mathematical facts, we'd expect convergence over time as we learn more, just like astronomy. Instead, on questions of what humans *ought* to do, we have deeper disagreement now than ever. Your astronomy comparison fails because the Earth's shape is about physical reality, not prescriptive demands. And your God objection proves my point: if goodness exists independently of God's command, then you've smuggled in a transcendent source anyway—you've just called it "moral facts". If it doesn't exist independently, then God's commands *create* morality, which is exactly what I've been saying all along.

You've trapped yourself in a false choice. Yes, "pain is bad" is a value claim, but value claims can still be *true or false*. A masochist doesn't experience pain as good—he experiences pain and *chooses* it for other goods (pleasure, identity, control). That's preference overriding disvalue, not negating it. Your convergence argument cuts both ways: moral disagreement persists because morality is *harder* than astronomy, not because it's unreal. We still disagree on quantum mechanics. Finally, your God dilemma proves objectivity doesn't require transcendence—moral facts can be fundamental brute features of reality, just like physical laws. You keep assuming grounding requires a conscious decreer. It doesn't.
