Ecclesiastes 2:12
So I turned to consider [secular] wisdom, madness, and folly; for what will the man do who succeeds the king? Nothing except what has already been done.
Ecclesiastes 1:17
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.
Ecclesiastes 7:25
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].
Ecclesiastes 1:9-10
That which has been is that which will be [again],
And that which has been done is that which will be done again.
So there is nothing new under the sun.
