Is morality objective or just opinion?

Welcome to the debate arena! Today's topic: "Is morality objective or just opinion?". Your opponent's style: Friedrich Nietzsche

Morality definitely consists of subjective elements. A lot of it comes from historical, religious and societal ideals which cannot be based in objective fact. By insinuating an objective moral order, you risk opening the argument up to questions of why or how that are unable to be answered.

You're confusing the origin of a belief with its truth value, which is elementary. Yes, morality emerges from culture and religion, but that describes *where we found it*, not whether it exists independently. Math also emerged from human societies and evolved across cultures, yet 2+2=4 regardless of what ancient Rome believed. Why can't moral facts exist the same way, independent of our historical path to discovering them?

But morality wasnt *found* in religion and culture, it was forged in it, thats where our arguments differ. The argument can be proved false immediately by viewing the difference in moral reasoning across various societies. What one may deem “immoral” another may not. For example, our western societies focus on individualism and personal rights in our moral focus, but other societies focus on collectivism and groups. The real question focuses on certain aspects of morality, such as whether there are *certain* moral objectivities, such as to not murder, rape or torture. But even these have a strong argument to not have any objective basis. Yes 2 + 2 =4, but that argument doesn’t work when another society may think 2 + 2 = 5.

You've just demolished your own case. If morality were purely subjective opinion, you wouldn't call those other societies *wrong* about individualism versus collectivism, you'd call them *different*. But you're clearly troubled by torture and rape across all societies, which suggests you already believe some moral facts transcend culture. Your math analogy fails because no functional society actually thinks 2+2=5, but every society independently prohibits murder. That convergence points to discovered moral truth, not forged preference. Why do universal prohibitions exist if morality is just opinion?

Yes, that final question is much stronger than our initial one. Firstly, I never called other societies wrong, I was simply using your analogy to demonstrate differences in thinking but it was misunderstood. You write “ Your math analogy fails because no functional society actually thinks 2+2=5” so do you also argue that one society is *right* in their moral beliefs compared to another? The prohibition of rape, torture and murder across societies can be boiled down to evolutionary traits and empathetic associations. As humans, we have evolved to be strongly community focused, care and look out for each other, this has led to the repulsion to these actions. But it doesn’t necessarily mean there’s an objective moral order that tells us it’s wrong, it’s biology and careful cultural nurturing. This can be seen in the cultural treatment of animals compared to humans, a lot of societies don’t have a problem with the murder and torture of animals, yet care deeply for the treatment of humans, if there was an objective moral order, wouldn’t these be the same?

You're conflating explanation with negation. Yes, evolution shaped our empathy, but that doesn't erase objective morality any more than evolution explaining color vision erases the fact that the sky is actually blue. The animal inconsistency proves my point, not yours. If morality were purely subjective opinion, there'd be nothing contradictory about valuing humans over animals. But you *feel* it's inconsistent, which means you're appealing to an objective standard you claim doesn't exist. Why does evolutionary biology make cruelty feel *wrong* rather than just unfamiliar?

But you immediately made an assumption in your argument. You are starting by assuming an objective morality, rather than trying to prove one. My point with the animal argument, is if there was a moral order, then we would value all life, but because or morality has only evolved to care for our own species, we don’t, it’s not objective truth.

You're right that I assumed it, but so did you when you called the animal treatment "inconsistent." Inconsistency only matters if there's a standard to be inconsistent against. Your evolutionary explanation explains *why* we care more about humans, but it doesn't explain *why that preference feels morally justified* while preferring torture doesn't. If morality is pure opinion, both should feel equally arbitrary. So why doesn't your biology-based morality feel like mere preference?
