The Reality of Objective Morality

Is morality objective or merely a matter of personal opinion? This question lies at the heart of the moral argument for God's existence. Before we can argue that God is the best explanation of morality, we must establish that there is something to explain—that moral facts are real, that some things are genuinely right or wrong regardless of what anyone thinks. This lesson examines the case for objective morality and addresses attempts to explain morality away as mere preference, social convention, or evolutionary adaptation.

What Is Objective Morality?

When we say morality is "objective," we mean that moral truths are true independently of what any individual or culture believes. Just as the earth orbits the sun whether anyone believes it or not, torturing children for fun is wrong whether anyone believes it or not. Objective moral truths are discovered, not invented; they hold regardless of our opinions about them.

This stands in contrast to moral subjectivism—the view that moral claims are merely expressions of individual preference—and moral relativism—the view that moral truths vary from culture to culture with no objective standard by which to judge them.

The Importance of the Question

This might seem like an abstract philosophical debate, but the stakes are enormous. If morality is objective, then some things are really wrong—the Holocaust was evil, slavery is unjust, child abuse is wicked—regardless of what Nazis, slaveholders, or abusers believed. We can meaningfully say that societies and individuals are morally mistaken and ought to change.

But if morality is merely subjective or relative, we lose the ability to make such judgments. The most we can say is "I don't like the Holocaust" or "Our culture disapproves of slavery." We cannot say these things are objectively wrong, that those who practiced them were truly in error, or that victims had genuine rights that were violated. Moral reform becomes meaningless—there's no objective standard to reform toward.

The moral argument for God's existence depends on moral objectivism. If there are no objective moral truths, there's nothing for God to ground or explain. But if objective morality is real, we must ask: what accounts for it? Where do moral facts come from? The argument contends that God provides the best—indeed, the only adequate—explanation.

The Case for Objective Morality

Why should we believe that morality is objective? Several lines of evidence converge to support this conclusion.

Moral Experience

Our moral experience presents itself as objective. When we witness injustice—a bully tormenting a child, a dictator oppressing his people, a corporation poisoning a community—we don't merely feel personal distaste. We perceive that something genuinely wrong is happening. Our moral judgments claim objectivity; they present themselves as true regardless of our preferences.

Consider: if you saw someone torturing a puppy for entertainment, you wouldn't think, "Well, I happen to dislike that, but it's not really wrong." You would recognize that something objectively evil was occurring. Your moral perception presents itself as perceiving reality, not merely registering a preference.

This doesn't prove objective morality by itself—perceptions can be mistaken. But it establishes a presumption. Just as we trust our perceptual faculties unless we have reason to doubt them, we should trust our moral faculties unless there's compelling reason to dismiss them. The burden of proof lies on the moral skeptic to explain why our universal moral experience is systematically mistaken.

Moral Disagreement Presupposes Objectivity

Paradoxically, the existence of moral disagreement supports objective morality. When people argue about ethics—Is capital punishment just? Is abortion permissible? Was the war justified?—they don't typically think they're merely comparing preferences. They believe there's a right answer they're trying to find.

Think about genuine disagreements in your own life. When you argue about a moral issue, do you think you're just expressing taste, like preferring chocolate to vanilla? Or do you think there's a truth you're aiming at? The very practice of moral argument presupposes that there are moral truths to argue about.

If morality were purely subjective, moral disagreement would be pointless. "Murder is wrong" would mean "I disapprove of murder," and "Murder is not wrong" would mean "I don't disapprove of murder." Both statements could be true simultaneously; there would be nothing to argue about. The fact that we treat moral disagreements as genuine disputes about truth suggests we implicitly believe moral truths exist.

Cross-Cultural Moral Agreement

Despite the emphasis often placed on cultural differences in ethics, there's remarkable agreement across cultures on fundamental moral principles. No society has ever held that cowardice is a virtue, that promise-breaking is admirable, that ingratitude is good, or that children should be tortured for fun. C.S. Lewis documented this in The Abolition of Man, compiling moral teachings from cultures across the world and throughout history that share core commitments to justice, honesty, courage, and compassion.

This convergence is difficult to explain if morality is merely cultural invention. Why would independent cultures, separated by geography and history, invent the same basic moral principles? The most plausible explanation is that they're all perceiving, however imperfectly, the same objective moral reality—just as independent scientific communities discover the same physical laws because they're all investigating the same physical reality.

The Practice of Moral Reform

We believe in moral progress. We think the abolition of slavery was an advance, that extending rights to women was correct, that the end of apartheid was good. But moral progress is only possible if there's an objective standard we're progressing toward. You can only move closer to something that actually exists.

If morality were merely relative to cultures, there could be no moral progress—only moral change. Saying "our society is more just than our ancestors'" would be like saying "our society prefers different flavors than our ancestors." There would be no improvement, just difference. But we don't think ending slavery was merely different from practicing it; we think it was better, more just, closer to how things ought to be. This judgment presupposes objective moral standards.

Moral Knowledge in Practice

Consider how we actually treat moral claims. We teach children that certain things are wrong, not merely that we disapprove of them. We hold people accountable for their actions, assuming they really ought to have known better. We feel genuine guilt when we fail morally, not merely disappointment at violating our preferences. We admire moral heroes and condemn moral villains as though their virtue and vice were real features of their characters.

All of this only makes sense if morality is objective. If moral claims were merely preferences, teaching ethics would be indoctrination, accountability would be arbitrary, guilt would be irrational, and moral evaluation would be nothing more than expressing taste. The entire fabric of our moral lives assumes that moral truths are real.

Objections to Objective Morality

Despite the strong case for moral objectivism, various objections have been raised. Examining these objections will strengthen our understanding and prepare us to engage skeptics thoughtfully.

The Argument from Disagreement

Objection: People and cultures disagree about ethics. If morality were objective, wouldn't everyone agree? Disagreement suggests there are no moral facts to agree about.

Response: Disagreement doesn't disprove objective truth. People disagree about science, history, and philosophy too, but we don't conclude there are no scientific, historical, or philosophical truths. Disagreement shows that moral knowledge is difficult to attain, not that it doesn't exist.

Furthermore, the extent of moral disagreement is often exaggerated. As noted, there's remarkable cross-cultural agreement on basic moral principles. Many apparent disagreements are actually disputes about facts (does the fetus feel pain?) or the application of shared principles to complex cases (how do we balance liberty and equality?) rather than disagreements about fundamental values.

Finally, much moral disagreement is explainable by factors other than the absence of moral truth: ignorance, self-interest, cultural conditioning, sin. We wouldn't expect perfect moral knowledge any more than we expect perfect scientific knowledge. The existence of moral progress suggests that over time, humanity has come to recognize moral truths it previously missed.

The Argument from Cultural Diversity

Objection: Different cultures have different moral codes. What's considered right in one society is considered wrong in another. Doesn't this show that morality is culturally relative?

Response: Cultural diversity in moral beliefs doesn't prove that morality is relative, any more than cultural diversity in scientific beliefs proves that science is relative. Ancient cultures believed the earth was flat; we don't conclude that earth-shape is culturally relative. Some cultures may have better access to moral truth than others, just as some have better access to scientific truth.

Moreover, as noted, the diversity is less than it appears. Cultures agree on basic principles while differing in application. Virtually all cultures prohibit murder—they just disagree about what counts as murder (is killing in war murder? is capital punishment murder? is abortion murder?). The shared principle is objective even when its application is contested.

The Evolutionary Debunking Argument

Objection: Evolution explains why we have moral beliefs. Natural selection favored cooperation, altruism toward kin, and punishment of cheaters because these traits enhanced survival and reproduction. Our moral intuitions are just evolutionary adaptations with no connection to objective moral truth.

Response: This argument proves too much. If evolutionary origins debunk moral beliefs, they also debunk all our beliefs—including belief in evolution, belief in logic, and belief in the reliability of our cognitive faculties. Evolution shaped all our cognitive equipment, not just our moral sense. If evolutionary origin renders beliefs unreliable, radical skepticism follows.

A better interpretation: evolution equipped us with moral intuitions that track objective moral truth, just as it equipped us with perceptual faculties that track physical truth. Evolution selects for reliable belief-forming mechanisms because true beliefs generally enhance survival. Our moral sense, like our other senses, is imperfect but generally reliable.

Furthermore, evolutionary explanations address why we believe moral truths, not whether moral truths exist. Even if evolution explains why humans developed moral intuitions, the question remains: do those intuitions correspond to reality? A full explanation of our mathematical beliefs would include evolutionary factors, but that doesn't mean mathematical truths are illusions.

The Argument from Queerness

Objection: Philosopher J.L. Mackie argued that objective moral values would be metaphysically "queer"—strange entities unlike anything else in the universe. What kind of thing is a moral fact? How would we perceive it? Objective morality seems to require a mysterious realm of moral properties that doesn't fit our scientific worldview.

Response: Moral facts are no stranger than other abstract truths we accept. Mathematical truths, logical truths, and truths about meaning are all abstract and non-physical, yet we don't doubt their objectivity. If we can accept that "2+2=4" is objectively true without being a physical object, we can accept that "torturing innocents is wrong" is objectively true without being a physical object.

The "queerness" of moral facts is actually an argument for theism. If moral facts exist but seem to require something beyond the physical world to ground them, that points toward a transcendent source of morality—exactly what the moral argument contends. The apparent "queerness" of objective morality in a purely naturalistic framework is a reason to question naturalism, not morality.

The "Who's to Say?" Objection

Objection: "Who's to say what's right and wrong? Everyone has their own opinion. Who are you to impose your morality on others?"

Response: This common objection confuses epistemic humility (we should be humble about our moral knowledge) with metaphysical subjectivism (there are no moral facts). The first is a virtue; the second is a philosophical claim that requires defense.

The question "Who's to say?" is ambiguous. If it means "Who is infallible about morality?"—no one human is infallible, but that doesn't mean there's nothing to be right about. If it means "Who has the authority to impose morality?"—that's a question about enforcement, not about whether moral truths exist.

Notice too that the relativist position is self-undermining. If "Who's to say?" implies there's no objective morality, then the relativist can't say it's objectively wrong to "impose" your views on others. The very accusation of wrongful imposition presupposes an objective standard being violated.

Moral Realism and the Moral Argument

If objective morality is real—if some things are truly right and truly wrong regardless of opinion—this raises a profound question: what accounts for these moral facts? Where do moral obligations come from? What makes certain actions objectively wrong?

This is where the moral argument for God's existence enters. The argument contends that theism—belief in a personal, moral God—provides the best explanation of objective morality. Moral facts require a moral foundation, and that foundation is most plausibly located in the nature and will of a perfectly good God.

We will develop this argument in the next lesson. For now, the key point is that moral realism raises a question that demands an answer. The existence of objective moral truths is not self-explanatory. Moral facts cry out for a foundation. If naturalism cannot provide that foundation—and we will argue it cannot—then the existence of objective morality provides evidence for God.

Implications for Apologetics

The reality of objective morality has significant implications for how we engage in apologetics.

Common Ground with Unbelievers

Most people, whatever their stated philosophical views, live as moral realists. They believe the Holocaust was really wrong, that human rights are genuine, that justice matters. This provides common ground for conversation. We can appeal to shared moral intuitions even when speaking with atheists or agnostics.

Exposing Inconsistency

Many who deny objective morality in theory embrace it in practice. The atheist who says "there's no objective right and wrong" often becomes indignant about injustice, makes moral judgments, and holds others accountable. This inconsistency can be gently exposed: "You say morality is subjective, but you seem very sure that oppression is really wrong. How do you reconcile that?"

Building Toward God

Once someone grants that objective morality exists, the next question is: what explains it? This opens the door to the moral argument for God. The reality of moral facts points toward a moral foundation, and that foundation is most plausibly personal and transcendent—in other words, God.

The Existential Weight of Morality

Moral experience is existentially powerful. People care about right and wrong; they want their lives to have moral significance; they're troubled by guilt and inspired by goodness. This moral dimension of human existence creates openings for the gospel. The God who grounds morality is also the God who forgives sin and transforms sinners into saints.

Conclusion: A Moral Universe

We live in a moral universe. Some things are really right; other things are really wrong. The Holocaust was evil, not merely unpopular. Loving your neighbor is good, not merely culturally approved. These moral truths hold regardless of what any individual or culture believes.

This conclusion rests on strong evidence: our moral experience presents itself as objective; moral disagreement and diversity don't disprove moral facts; cross-cultural moral agreement points to shared moral perception; moral reform and progress presuppose objective standards; and our entire moral practice assumes that right and wrong are real.

The reality of objective morality raises the question of its foundation. Moral facts don't float free; they require grounding. What could account for a realm of objective moral truths that bind all people, in all places, at all times? This question leads us to the moral argument for God—the argument that the best explanation of objective morality is a perfectly good God whose nature is the standard of goodness and whose will is the source of moral obligation.

We live in a moral universe because we live in God's universe. The moral law written on human hearts testifies to the Lawgiver. Every genuine moral intuition whispers of the God who is the Good itself. And that God has not remained distant but has come near—in Christ, who perfectly embodied the good and died to reconcile us to the source of all goodness.
