“I have seen everything that is done under the sun, and behold, all is vanity and a striving after wind. 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. For in much wisdom is much vexation, and he who increases knowledge increases sorrow.”(Ecclesiastes 1:14‭, ‬17‭-‬18)
