Why is it that we thrive on questions?
Before we answer, it is important to stress that there is no shame in asking questions.
Though it may seem that one who asks questions admits that he lacks knowledge or understanding, the truth is quite the opposite.
In a sense, it is the scholar – the one with the most knowledge of all – who asks the most questions.
A non-scholar has no questions to ask, not because he knows the most but because he knows the least.
In giving us the Torah, God is not selling us tranquility.
Tranquility is not part of the reward.
Rather, one who reaches a state in which he has no more questions, difficulties, doubts, or problems, is not the ideal man but, on the contrary, is one who has left the world entirely.
–Rabbi Adin Steinsaltz
