“So I turned to consider wisdom.
I considered madness.
I considered folly.
What can one do
Who comes after the king?
Only what has already been done.
Then I saw that wisdom excels folly
As light excels darkness.
‘The wise have eyes in their head.
But fools walk in darkness.’”
Now Qoheleth considered, wisdom, madness, and folly again. What happens when a king dies? The next king will pretty much do what the preceding king had done. Finally, he saw the light. He realized that wisdom exceeds folly just like light exceeds darkness. Wisdom is light while folly is darkness. This picks up the main theme of Proverbs again. The wise have eyes in their head, but the fools are blind, walking in darkness.
