Every quarrel assumes a rule that both sides already know.
Lewis opens with ordinary arguments, not with religion. When people complain about a broken promise or a jumped queue, they do not just say they dislike it; they say the other person has broken a standard. That shared appeal is what makes it a quarrel rather than a fight, and it is the first clue he follows.
Two facts sit under all clear thinking about ourselves: we believe we ought to behave a certain way, and we do not.
Book One rests on this pair. Lewis argues that people everywhere feel bound by a standard of decent behaviour, and that nobody fully keeps it. Even our excuses give us away, because we would not bother making them if we did not believe in the rule.
Instincts are the keys of the piano; the Moral Law is the sheet music that says which one to play.
Lewis answers the claim that morality is only herd instinct. When the urge to help someone in danger fights the urge to stay safe, a third thing judges between them and often backs the weaker one. That judge, he argues, cannot simply be one of the instincts.
To call one morality better than another is to measure both against a standard that is neither.
Against the idea that morals are mere convention, Lewis points out that we do judge between them, for example when we call Christian morality better than Nazi morality. If no code were better than another, moral reform would be impossible and progress would be an empty word.
Lewis says Christianity begins in dismay, not in comfort.
Book One ends on unease. If there is a power behind the Moral Law and we keep breaking it, we are at odds with that power. Lewis argues that talk of forgiveness means little to someone who does not think there is anything to forgive, so the comfort only comes after the bad news.
Lewis argues that great moral teacher is the one verdict on Jesus that is not open to us.
This is the argument now often summed up as lunatic, liar or Lord. Because of the claims Jesus made about himself, Lewis says, he was either mad, something worse, or telling the truth. Critics reply that it assumes the gospels report his words accurately, which is the point most debates turn on.
Morality has three jobs, like a fleet: keep the ships from colliding, keep each one seaworthy, and know where the fleet is going.
Book Three opens with this picture. Most public talk about morality covers only the first job, fair play between people. Lewis argues the inner state of each person matters just as much, and that both depend on what you think a human life is for.
Pride is the great sin because it is competitive by nature: it enjoys having more than the next person.
Lewis calls pride the vice that almost everyone dislikes in others and almost no one notices in themselves. Other faults can bring people together; pride sets each person against everyone else. His test is simple: the more it annoys you when someone else is proud, the more of it you probably have.
You thought you were being given a tidier cottage; the builder had a palace in mind.
In Book Four Lewis borrows a parable from George MacDonald. You invite God in to fix the leaks, and then he starts knocking down walls and adding wings. Lewis uses it to explain why the change Christianity describes is harder than expected: the aim is not a nicer version of you but a new kind of person.
