Man learns by asking
Since life began, children have learned from parents by asking. The knowledge they teach us is useful, but the most useful is the knowledge that you obtain from many questions, because the one who learns from asking has a desire to learn, unlike... Whoever sits in a seat and listens to knowledge, and for this reason teachers in schools must make their students inquire and hint to them so that they come up with questions themselves. A class, as they call it, that includes questions and answers is better than an entire day in which knowledge is imposed on the students, and most of them are asleep and do not know what the teachers are talking about. Virtuous people, be sure to be aware of the questions. Even if the curricula had many questions, it would have helped teachers and students achieve mastery.
