Ecclesiastes 1:13-18

And I set my mind to seek and explore by [man’s] wisdom all [human activity] that has been done under heaven. It is a miserable business and a burdensome task which God has given the sons of men with which to be busy and distressed. I have seen all the works which have been done under the sun, and behold, all is vanity, a futile grasping and chasing after the wind. What is crooked cannot be straightened and what is defective and lacking cannot be counted. I spoke with my heart, saying, “Behold, I have acquired great [human] wisdom and experience, more than all who were over Jerusalem before me; and my mind has observed a wealth of [moral] wisdom and [scientific] knowledge.” And I set my mind to know [practical] wisdom and to discern [the character of] madness and folly [in which men seem to find satisfaction]; I realized that this too is a futile grasping and chasing after the wind. [1 Thess 5:21] For in much [human] wisdom there is much displeasure and exasperation; increasing knowledge increases sorrow.
