'Madness and Folly' in the Bible

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.

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.
