Ecclesiastes 2:16

(16) It might be urged on behalf of the Solomonic authorship that Solomon himself might imagine that in the days to come he and his wisdom would be forgotten, but that such a thought does not become a long subsequent writer who had been induced by Solomon’s reputation for wisdom to make him the hero of his work. It would seem to follow that the writer is here only giving the history of Solomon’s reflections, and not his ultimate conclusions. Better to omit the note of interrogation after “wise man,” and put a note of exclamation after “fool,” the “how” being used as in Isaiah 14:4; Ezekiel 26:17.
