Ecclesiastes 1:16-18 HCSB
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.” I applied my mind to know wisdom and knowledge, madness and folly; I learned that this too is a pursuit of the wind.
For with much wisdom is much sorrow;
as knowledge increases, grief increases.
