13 Then I saw that wisdom excelleth folly, as far as light excelleth darkness.
14 The wise man's eyes are in his head; but the fool walketh in darkness; and I myself perceived also that one event happeneth to them all.
15 Then said I in my heart, As it happeneth to the fool, so it happeneth even to me; and why was I then more wise? Then I said in my heart, that this also is vanity.
16 For there is no remembrance of the wise more than of the fool forever; seeing that which now is in the days to come shall all be forgotten. And how dieth the wise man? as the fool.
17 Therefore I hated life; because the work that is wrought under the sun is grievous unto me; for all is vanity and vexation of spirit.
18 Yea, I hated all my labor which I had taken under the sun, because I should leave it unto the man that shall be after me.
19 And who knoweth whether he shall be a wise man or a fool? yet shall he have rule over all my labor wherein I have labored, and wherein I have showed myself wise under the sun. This is also vanity.
20 Therefore I went about to cause my heart to despair of all the labor which I took under the sun.
21 For there is a man whose labor is in wisdom, and in knowledge, and in equity; yet to a man that hath not labored therein shall he leave it for his portion. This also is vanity and a great evil.
22 For what hath man of all his labor, and of the vexation of his heart, wherein he hath labored under the sun?
23 For all his days are sorrows, and his travail grief; yea, his heart taketh not rest in the night. This is also vanity.
