Appendix A: The Moral Law: Key Texts and Arguments

The Moral Law argument is the starting point for both the agnostic and the atheist conversation. The following is a quick-reference summary.

The Argument in Three Moves

1. Objective moral values and duties exist — demonstrated by the universal human intuition that some things (genocide, child abuse, betrayal) are genuinely wrong, not merely culturally disapproved
2. If God does not exist, objective moral values do not exist — in a purely material universe, there is no "ought," only "is"; moral claims reduce to personal preferences or evolutionary byproducts
3. Therefore God exists — the Moral Law requires a Lawgiver

Key Texts

• C.S. Lewis, Mere Christianity, Book 1: "Right and Wrong as a Clue to the Meaning of the Universe"
• William Lane Craig, Reasonable Faith, Chapter 3: The Moral Argument
• Romans 2:14–15 — the law written on the hearts of those who do not have the law

Common Objections and Responses

Objection: Evolution explains our moral intuitions.

Response: Evolution explains why we have moral feelings. It does not ground moral truth. If evolution had made torturing children useful for survival, it would have produced the opposite intuition. The evolutionary account destroys the moral judgments the atheist most wants to make.

Objection: Different cultures have different moral codes, proving morality is relative.

Response: Cultural moral codes differ at the margins. No culture has ever valued cowardice over courage, treachery over loyalty, or cruelty over kindness as universal ideals. The differences are in application. The underlying Law is remarkably consistent.
