15That which is crooked cannot be made straight; and that which is wanting cannot be numbered.
16I spoke with my own heart, saying: 'Lo, I have gotten great wisdom, more also than all that were before me over Jerusalem'; yea, my heart hath had great experience of wisdom and knowledge.
17And I applied my heart to know wisdom, and to know madness and folly — I perceived that this also was a striving after wind.
18For in much wisdom is much vexation; and he that increaseth knowledge increaseth sorrow.
