"المشكلة كلها في العالم أن الحمقى والمتعصبين دائمًا متأكدين جدًا من أنفسهم، والأشخاص الحكماء مليئون بالشكوك."

Simplified Meaning:

Some people with little knowledge or extreme beliefs often seem very sure of their opinions. However, people who are wiser and more knowledgeable tend to have more questions and uncertainties. For example, imagine two students in a class debate. One student loudly insists they know everything about the topic, even though they have only read a few articles. The other student, who has studied the subject deeply, offers their thoughts but acknowledges there might be more to learn. The second student shows that being wise often means understanding that there is always more to know. In daily life, it's important to remember that having doubts and asking questions is a sign of intelligence and growth, while being too confident without solid understanding can be misleading. So, one should stay humble and open-minded, always willing to learn and listen to others.
