Lewis argues that the Moral Law is simply a description of what human beings usually do.

### Why this is right The statement is false because Lewis distinguishes what people actually do from what they ought to do. He argues that people regularly violate the Moral Law, so it cannot merely describe their usual behaviour. ### The concept A descriptive statement reports a pattern, such as how objects fall. A moral statement makes a claim about what people should do, even when they do something else. Lewis’s argument depends on this difference: human conduct supplies the facts, while moral obligation evaluates them. ### The other options - **True**: This confuses moral obligation with a description of behaviour. Lewis explicitly says people fail to keep the law. ### Terms - **Descriptive**: Reporting what happens, rather than prescribing what ought to happen. ### Remember For Lewis, the Moral Law says what people ought to do, not what they reliably do.
