Reason and authority are the two brightest lights in the world.

Explanation

The law rests on two pillars — rational principle and established precedent; where both converge, the law speaks with its greatest force. (Duplicate maxim — see also 1.5.260.)

Where this applies

• The strongest legal position combines both logical reasoning and established precedent.
• Reason and authority are the two pillars of the law.
• When both sound reasoning and case authority agree, the argument is at its strongest.
