I’ve had more than a few long‑trail conversations about objective morality, often while hiking ridgelines or nursing coffee on a gray Puget Sound morning. The claim usually lands the same way: there must be an objective moral truth “out there,” something real and mind‑independent that tells us what is right or wrong regardless of what anyone thinks. It sounds comforting; like a granite outcrop underfoot. But when we slow down and test the footing, the stone crumbles.

At the center of the problem is a philosophical mismatch. Objective truths, by definition, are mind‑independent facts; entities or realities that remain what they are even if every mind disappears (IEP, Objectivity, 2026). Morality, however, belongs to a different category entirely: it is an evaluative framework built from perception, judgment, empathy, culture, and social cognition. Even philosophers who defend moral realism acknowledge that moral statements are value claims, not descriptive facts about the world the way carbon atoms or gravitation are (Philopedia, Moral Realism, 2026). And when a concept depends on minds to exist, it cannot simultaneously be mind‑independent. That contradiction alone doesn’t kill objective morality, but it does force us to ask harder questions.

Key Point One: Commonality Is Not Objectivity

A lot of people argue that the cross‑cultural overlap in prohibitions, murder, theft, betrayal, shows that some moral truths must be objective. But commonality is not evidence of universality; it is evidence of convergent strategies. Social mammals, including humans, share constraints: cooperation is rewarded, extreme selfishness is punished, and group cohesion keeps you alive. Evolutionary pressures nudge species toward recognizable moral‑like patterns; reciprocity, fairness, empathy, not because these values exist “out there,” but because they keep social species functioning. Moral realism tries to treat these patterns as discoveries of an independent moral realm; a more grounded explanation is that we are observing biological and cognitive convergence, not objective truth. Realists themselves note that even if moral truths existed, we would still be perceiving them through the filter of psychology, culture, and history (Philopedia, Moral Realism, 2026).

Key Point Two: Objectivity Requires a Truth‑Maker—Morality Doesn’t Have One

For a moral claim to be objective, something in the world must make it true independent of minds. With scientific facts, the truth‑makers are concrete: chemical bonds, physical forces, measurable quantities. But what is the truth‑maker for the statement “cruelty is wrong”? Philosophers have proposed natural properties, non‑natural properties, divine commands, rational consistency, or “intrinsic badness,” but none of these candidates satisfy the requirements of objectivity laid out in the very definition theists and moral realists rely on. Even defenders of objective morality split sharply over what these truth‑makers would be, which is telling. Without a stable truth‑maker, “objective morality” floats free of the very structure objectivity requires (IEP, Objectivity, 2026; Philopedia, Moral Realism, 2026).

Speaking personally, the more I’ve thought about it, the more it feels like objective morality is a category error dressed as metaphysics. I understand the impulse; we want our deepest moral commitments to be more than preferences or evolved instincts. But wanting solidity is not the same as having it. What we actually share across cultures and species is something less mystical and far more interesting: a set of adaptive cognitive strategies for navigating social life. That doesn’t cheapen morality. If anything, it makes it more human, more dynamic, and more ours to shape rather than inherit.

So when the conversation turns to objective morality, I prefer to ask: are we demanding the universe hold our values for us, or are we willing to own the responsibility of building them together? That’s the real challenge, and we don’t get to outsource it to mind‑independent facts that simply aren’t there.
