14. I have seen all the things that are done under the sun and have found everything to be futile, a pursuit of the wind.
15. What is crooked cannot be straightened; what is lacking cannot be counted.
16. I said to myself, “Look, I have amassed wisdom far beyond all those who were over Jerusalem before me, and my mind has thoroughly grasped wisdom and knowledge.”
17. I applied my mind to know wisdom and knowledge, madness and folly; I learned that this too is a pursuit of the wind.
18. For with much wisdom is much sorrow; as knowledge increases, grief increases.
