“These are questions that had been going through Thereza’s head since she was a child. Indeed, the only serious questions are the one that a child can formulate. Only the most naive questions are truly serious. They are the questions with no answer. A question with no answer is a barrier that cannot be breached. In other words, it is questions with no answer that set limits of human possibilities, describe the boundaries of human existence.”
