전도서 4:12의 Quotation

The Talmud in the Chapter of Fundamentals (Pirke Avot, 4.1) makes the connection between wisdom and capacity for learning. "Ben Zoma says, 'Who is wise? He who learns from all men,' as it is said, 'From all my teachers I gained wisdom (Psalms 119.99).'" Wisdom is not the accumulation of learning, but the capacity for learning. In this sense, the wisdom of the child may exceed the wisdom of an old king.

The old and foolish king is not cautious because his power has blinded him to the underlying uncertainty of things. Even though he may have access to every pleasure under the sun, he is not so well off as the poor child who is full of potential and capable of learning.
