“‘What is crooked cannot be made straight.
What is lacking cannot be counted.’
I said to myself.
‘I have acquired great wisdom.
My wisdom surpasses all
Who were over Jerusalem before me.
My mind has had great experience of wisdom.
My mind has had great experience of knowledge.
I applied my mind to know wisdom.
I applied my mind to know madness.
I applied my mind to know folly.
I perceived that this also is but a chasing after wind.
In much wisdom
Is much vexation.
Those who increases knowledge
This book once again has the first person singular of Qoheleth speaking. He points out, quite correctly, that the crooked cannot be made straight. However, you can come close. On the other hand, there is no doubt that you cannot count something that is not there. Then Qoheleth gets quite personal. He explains that he has great wisdom and knowledge, greater than anyone whoever was in Jerusalem before him. He knows the difference between wisdom, madness, and folly. In a kind of reversal of the Proverbs, he seems to imply that that with all this wisdom, he is still like chasing after the wind. More problems and vexation come with wisdom. There is an increase in sorrow that comes with more knowledge. Wisdom is not the be all and end all like in Proverbs.
