Discussion Questions

6 questions

1.Lewis begins with the observation that when people quarrel, they appeal to a standard they both assume the other person knows — 'That's not fair,' 'You promised.' What is he trying to show with this simple, everyday observation?

2.He distinguishes between the Law of Nature (how things like trees and gravity *do* behave) and the Law of Human Nature (how humans *ought* to behave but often don't). Why is this distinction crucial to his argument?

3.Lewis acknowledges the objection that morality is just social conditioning — that we learned 'fair play' from our upbringing. How does he respond to this? Do you find his response convincing?

a.Can you think of a moral conviction you hold that *cannot* be explained by your upbringing alone?

b.What would it mean if morality really were just social conditioning — what would be lost?
