In context

15So I commended the enjoyment of life, because there is nothing better for a man under the sun than to eat and drink and be merry. For this joy will accompany him in his labor during the days of his life that God gives him under the sun.

17I saw every work of God, and that a man is unable to comprehend the work that is done under the sun. Despite his efforts to search it out, he cannot find its meaning; even if the wise man claims to know, he is unable to comprehend.
