The Madness and Folly of Wisdom

This is very true.  I actually googled "how to increase wisdom" and the last verse (18) came up.  It reminded me of that movie "A Beautiful Mind" too.  The deeper you go into rabbit holes the more confused and lost you get.  The more a person knows of this world the more sorrow they get for sure.  Think of a happy child who doesn't know how the body will age, how the world is suffering, how death is near; how all loved ones will one day die, and for the Christian, how so many friends, family, and billions of others in the world may not enter the Kingdom of Heaven.

The Vanity of Wisdom

¹² I the Preacher have been king over Israel in Jerusalem. ¹³ And I applied my heart^[f] to seek and to search out by wisdom all that is done under heaven. It is an unhappy business that God has given to the children of man to be busy with. ¹⁴ I have seen everything that is done under the sun, and behold, all is vanity^[g] and a striving after wind.^[h]

¹⁵ What is crooked cannot be made straight,
    and what is lacking cannot be counted.

¹⁶ I said in my heart, “I have acquired great wisdom, surpassing all who were over Jerusalem before me, and my heart has had great experience of wisdom and knowledge.” ¹⁷ And I applied my heart to know wisdom and to know madness and folly. I perceived that this also is but a striving after wind.

¹⁸ For in much wisdom is much vexation,
    and he who increases knowledge increases sorrow.
