הוֹלֵלָה

So I set my mind to know wisdom and madness and folly; I learned that this, too, is a pursuit of the wind.

Then I turned to consider wisdom and madness and folly; for what more can the king’s successor do than what has already been accomplished?

I directed my mind to understand, to explore, to search out wisdom and explanations, and to understand the stupidity of wickedness and the folly of madness.

This is an evil in everything that is done under the sun: There is one fate for everyone. Furthermore, the hearts of men are full of evil and madness while they are alive, and afterward they join the dead.
