You Believe in Objective Morality. Here's What That Means.
Torturing a child for entertainment is wrong. It is not wrong merely for some cultures, and it is not wrong only according to majority vote; it is wrong everywhere, always, without exception, no matter what any government, society, or century decides.
You believe that. Everyone does. And that belief is a bigger problem for atheism than most atheists want to admit.
The Claim Nobody Actually Lives By
Ask a committed moral relativist whether slavery was really wrong, or whether it was just "wrong for us, in our culture, at this point in history." Watch them abandon relativism in real time. Nobody actually believes morality is a matter of taste once you push past the dorm-room version of the claim. In every argument about justice, fairness, and cruelty, people act every day as though some things are simply, objectively true about right and wrong, independent of what anyone thinks about them.
That's the starting point, and it isn't a philosophical abstraction; it's a fact about how every human being actually lives.
Atoms Don't Produce Obligations
Here's the problem naturalism can't solve. If the universe is nothing but matter, energy, and the laws of physics operating on both, then it can tell you what is. It cannot tell you what ought to be. Chemistry describes reactions. It does not issue commands. A brain state is a fact about neurons firing; it is not, by itself, a duty. You cannot get "ought" from "is" no matter how long you stare at the periodic table.
Philosophers have called this the is-ought gap since Hume, and naturalism has never closed it. Which means every atheist who insists that racism is objectively evil, that child abuse is really wrong, that some historical atrocity was a genuine moral catastrophe and not just a cultural disagreement, is reaching for a category their own worldview doesn't supply. They're using moral language that requires a moral lawgiver while denying the lawgiver exists.
"Evolution Explains Morality" Doesn't Answer the Question
The most common comeback is that evolution wired us for cooperation because cooperative groups survived better than selfish ones, and that much is fine as far as it goes. That might explain why humans believe certain things are moral, but it does nothing to establish that those beliefs are true.
Evolution selects for survival, not for truth. If believing cruelty was virtuous had somehow improved reproductive odds on the savanna, natural selection would have wired that belief in just as readily as it wired in our current instincts. A process that optimizes for survival has no mechanism for tracking moral truth; it only tracks what keeps genes propagating. So the evolutionary story, at best, explains the origin of a psychological sense of right and wrong. It cannot explain why that sense corresponds to anything actually, objectively true. You end up with strong feelings and no foundation.
C.S. Lewis Saw the Real Disagreement
C.S. Lewis made the point decades ago in Mere Christianity: people argue about morality constantly, but pay attention to what they're arguing about. They appeal to fairness. They demand consistency. They say "that's not fair" and expect the other person to recognize the standard, not shrug it off as a preference. Two people who disagree about a specific moral question are not disagreeing about whether a real standard exists; they're disagreeing about how to apply it. The disagreement itself proves the standard is there. Nobody debates the existence of a strike zone by arguing about whether a particular pitch was a strike.
That near-universal moral sense, cutting across cultures, centuries, and worldviews with remarkable consistency on the big questions, needs an explanation more than a mere byproduct of survival pressure can offer.
The Argument, Stated Plainly
- If objective moral values exist, they require a transcendent, unchanging standard beyond human opinion, culture, or biology.
- Objective moral values do exist; cruelty for its own sake is genuinely wrong, not just disfavored.
- Therefore, a transcendent moral standard exists.
That standard needs a source with the authority to bind every person, in every culture, in every era, and that is a description of a being, not a force. Gravity doesn't issue commands. Only a person can. Theists have a name for that person. Naturalism has no candidate at all.
Not a Trick, But a Description of the Life You're Already Living
You didn't need a philosophy course to feel outrage at injustice; you were already living inside a moral order this argument merely names. That recognition is sharp, immediate, and non-negotiable. It is evidence, and it points somewhere.
The next question is the one this whole series is building toward: if there's a moral Lawgiver, has He done anything to show Himself?
