Ecclesiastes 1:15-18

That which is crooked cannot be made straight; and that which is wanting cannot be numbered. I communed with mine own heart, saying, Lo, I have gotten me great wisdom above all that were before me in Jerusalem; yea, my heart hath had great experience of wisdom and knowledge. And I applied my heart to know wisdom, and to know madness and folly: I perceived that this also was a striving after wind. For in much wisdom is much grief; and he that increaseth knowledge increaseth sorrow.
