Reason is a ray of divine light.

Explanation

The capacity for reason is God-given, and the law, being founded on reason, partakes of a divine character — an unreasonable law is no law at all. (Duplicate maxim — see also 12.11.6.)

Where this applies

• Someone argues that reason has no role in law.
• A legal rule is challenged as unreasonable and thus invalid.
