Ecclesiastes 7:23-25

YLT(i) 23 All this I have tried by wisdom; I have said, `I am wise,' and it is far from me. 24 Far off is that which hath been, and deep, deep, who doth find it? 25 I have turned round, also my heart, to know and to search, and to seek out wisdom, and reason, and to know the wrong of folly, and of foolishness the madness.
