Ecclesiastes 1:13-17

¹³And I directed my heart to inquire and to search out by wisdom concerning all that is done under the heavens: this is an evil employment which God hath given to the sons of man to busy themselves therewith.

¹⁴I saw all the deeds that are done under the sun: and, behold, all is vanity and a torture of the spirit.

¹⁵What is crooked cannot be made straight; and that which is defective cannot be numbered.

¹⁶I spoke with my own heart, saying, Lo, I have truly obtained greater and more wisdom than all those who have been before me over Jerusalem: yea, my heart had seen much wisdom and knowledge.

¹⁷And I directed my heart to know wisdom, and to know madness and folly; but I have perceived that this also is a torture of the spirit.
