He who questions well learns well.

Explanation

(English-origin maxim.) Effective cross-examination and forensic inquiry are the engines of truth — a lawyer who asks the right questions will uncover what no amount of passive observation reveals.

Where this applies

• A skilled cross-examiner asks precise, targeted questions and uncovers the key inconsistency in the witness's testimony that no amount of direct examination had revealed.
• A Socratic teacher draws out the correct legal principle from a student by asking increasingly pointed questions, demonstrating that good questioning is the fastest path to understanding.
• A mediator resolves a complex contract dispute by asking each party the right questions until the real source of disagreement emerges, proving that questioning well is learning well.
