14 I have seen all the works that are done under the sun; and, behold, all is vanity and like grasping the wind.
15 That which is crooked cannot be made straight: and that which is lacking cannot be numbered.
16 I communed with my own heart, saying, Lo, I have come to greatness, and have gotten more wisdom than all they that have been before me in Jerusalem: yea, my heart had great experience of wisdom and knowledge.
17 And I set my heart to know wisdom, and to know madness and folly: I perceived that this also is like grasping the wind.
18 For in much wisdom is much grief: and he that increases knowledge increases sorrow.
