Ecclesiastes 7:23-25

I have tested all this with wisdom. I said, “I will be wise [independently of God],” but true wisdom was far from me. Whatever has been is far off, deeply remote and exceedingly mysterious. Who can discover it [for it is beyond the grasp of man]? [Job 28:12-28; 1 Cor 2:9-16] I turned around and directed my heart to know, to investigate and to seek [skillful and godly] wisdom and the reason for things, and to know that wickedness is folly and that foolishness is madness [leading to stupidity and recklessness].
