When a detective investigates a murder, they assume that murder is wrong — but where does that moral knowledge come from, and what does it tell us about the nature of reality?

Discussion Questions

6 questions

1.Wallace presents the moral argument for God's existence: the observation that objective moral truths (e.g., torturing children for fun is wrong) seem to exist independently of what any individual or culture believes. How does he develop this argument in detective terms? What "evidence at the scene" of moral experience points toward a moral Lawgiver?

2.He distinguishes between moral relativism (morality is culturally constructed) and moral realism (some things are genuinely, objectively wrong regardless of what anyone thinks). Where do you land on this spectrum? Have you ever encountered a situation where you felt something was wrong — not just that you disliked it — but genuinely, universally wrong?

3.Wallace points out that moral relativists typically argue from moral absolutes — they say things like "it is wrong to impose your morality on others," which is itself a moral absolute. Have you noticed this self-refuting tendency in conversations about morality? How would you press on it gently in a real conversation?
