Book 1: Right and Wrong as a Clue to the Meaning of the Universe
Chapter 1: The Law of Human Nature
Humans share an innate moral law, a universal sense of right and wrong, which transcends culture and time. This moral law is not mere habit or social conditioning since people recognize it as a standard they often fail to meet but feel obligated to follow. It points to an objective moral order beyond personal preferences. The existence of this law suggests a guiding force or lawgiver. People appeal to this law in disputes, implying its reality. The moral law shapes conscience and judgment. Lewis frames this law as central to understanding human nature.
Chapter 2: Some Objections
Lewis addresses common objections claiming morality is merely social convention or instinct. He argues these fail to explain why people feel they ought to behave in certain ways, not just what they do. Moral obligation is prescriptive and universal, unlike mere habit. People hold themselves accountable to standards that transcend societal norms. The objections fail to account for moral progress and reform. Lewis insists morality cannot be reduced to instinct or social pressure. This chapter defends the objectivity of the moral law.
Chapter 3: The Reality of the Law
The very act of arguing about right and wrong presupposes a shared moral standard. This chapter asserts the moral law’s real and universal existence. It is not relative or invented but something people recognize and appeal to. The law informs conscience and conscience judges actions. The existence of moral disagreement implies an underlying standard. Lewis emphasizes that this standard is binding for all humans. Recognizing the law is key to moral discourse.
Chapter 4: What Lies Behind the Law
Lewis reasons that the best explanation for the universal moral law is a divine lawgiver. This lawgiver must be personal, intelligent, and good. The law reflects a mind that commands and judges. Human morality derives from this source rather than random evolution or social contract. The moral law’s existence points to God’s reality and character. This divine origin grounds objective ethics. Lewis builds the case for God as moral authority.
Chapter 5: We Have Cause to Be Uneasy
Humans regularly break the moral law, revealing moral failure and guilt. Lewis concludes humanity is in a state of moral bankruptcy. No human effort alone can fully rectify this failure. This moral condition necessitates a remedy beyond human capacity. Lewis points toward the need for divine intervention and salvation. Recognition of guilt is a crucial step toward redemption. The chapter prepares for discussing Christianity’s solution.
Book 2: What Christians Believe
Chapter 1: The Rival Conceptions of God
Lewis contrasts views of God as an impersonal force, malevolent power, or personal loving Creator. He argues the latter best explains human experience and the moral law. The personal God creates meaning and moral order. The chapter sets the stage for Christian belief in a relational God. It rejects impersonal or indifferent conceptions of divinity. Lewis emphasizes God’s goodness and love. This personal God invites response and relationship.
Chapter 2: The Invasion

Chapter 3: The Shocking Alternative

It is the foundation for salvation.
Chapter 5: The Practical Conclusion
