Ecclesiastes 2:14,15

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.

It is worth the Reader's close observation, that Solomon, having in the foregoing verses ascertained the little pretensions that arise from sensual gratifications to happiness; in these verses he sets himself to make a similar estimate of those pleasures which arise from mental enjoyments. And he proves that those, like the former, are alike vain and unsatisfying. Reader! follow the Preacher's observations with your own. Wherein is happiness to be found? among the book-worms, and the studious of the earth? If Christ be not the object of pursuit; what, less than vanity marks all? The termination to the worldly wise and the fool, is one and the same. All is vanity.
