We all know the typical answer that the reason we ask questions at the seder is to keep the kids interested, but if that is the reason then why do adults ask each other questions on Passover when there are no children present? What is the true purpose of the questions that we ask at the seder table?
Asking questions is a valuable educational tool for adults and not only for children. The Secular term for it is the Socratic method of learning as Socrates was the one who introduced it to the Western world.
When one hears a question, he immediately becomes curious. His curiosity prepares him to receive the answer. Just telling something to another person without awakening their curiosity first will result in the person not absorbing the information fully.
