There once lived in Greece a learned man.He was so well-known for his wide knowledge of almost everything that lots of people from all over the country came to learn things from him.The great man taught his students whole-heartedly and answered their questions with great patience.
One day a student asked him,“You are our teacher,but why do you have more questions about things than we do?On the contrary,we students have far more than you.”
With a smile,the teacher drew two circles—one as large as a big wheel,the other smaller.
“Of course,I’ve learned much more.But a teacher does not necessarily have fewer questions than his students.Now,look at these two circles.Within the big one is my knowledge of things and within the smaller yours.Out of the circles is what is still unknown to us.Since mine is larger,the line that marks out the circle is longer.That means I have more chances to face what is still unknown.And that’s why I myself have more questions than you do.The more you learn,the more questions you have.You will never learn enough,you know.”
