In secular or naturalist view, some argue that moral facts exist as part of the universe’s structure.
Just like mathematical truths (e.g., 2+2=4) or physical laws exist regardless of belief. They’re not “created” but discovered — just like gravity wasn’t invented, just revealed.
Some argue we evolved moral intuitions because they’re adaptive, but those intuitions track real moral facts, the way our eyes evolved to track light. Morality isn’t arbitrary, but it’s also not supernatural.
Philosophers like Kant argued that rational beings can discover moral laws (like the Categorical Imperative) through reason alone — no divine authority required.
If you believe in objective morality, you have to explain where it comes from, and why it binds us.
Atheists say that moral facts might just be part of the fabric of reality — like math or physics. That on its own makes no sense.
If someone says moral truths "just exist," like “Murder is wrong,” you can ask: Why? What makes it wrong?
In physics, gravity has measurable effects and a mechanism. But with morality, if there's no God, then saying “torture is wrong” is just a floating truth with no cause, no enforcer, and no explanation.
Even if moral truths exist, why should they apply to me?
Without a mind behind morality — like God — there’s no authority to hold us accountable. It’s like having traffic laws with no government or enforcement — suggestions, not obligations.
Evolution doesn't prove morality, just explains feelings.
If our sense of morality evolved to help us survive, that just means we feel things are right or wrong. But evolution doesn’t care about truth, just survival.
So how do you get from “we evolved to cooperate” to “cooperation is objectively good”?You can’t. That’s jumping from “is” to “ought”.
Abstract moral values = metaphysical weirdness
Saying moral values just exist somewhere — like Platonic objects — is kind of like believing in invisible unicorns. Why should we believe in a realm of objective moral facts that we can’t see, measure, or test?
Ironically, God is a simpler explanation — one eternal moral mind, rather than an unexplained realm of floating moral truths.
So yeah — if someone rejects God but wants to keep objective morality, they’re standing on thin ice unless they can explain:
Where moral truths come from?
