13. I realized that wisdom has an advantage over folly, just as light has an advantage over darkness.
14. The wise man can see where he is walking, but the fool walks in darkness. Yet I also realized that both of them suffer the same fate.
15. So I said to myself, “If I also suffer the same fate as the fool, what advantage is my great wisdom?” So I said to myself, “This also is vanity!”
16. Certainly no one will remember the wise man or the fool in future generations. When future days come, both will have been forgotten already. How is it that the wise man dies the same as the fool?
17. So I hated life because the work done under the sun is grievous to me. For everything is vanity and chasing wind!
18. So I hated all my toil with which I have toiled under the sun, for I must leave it behind to someone who will be after me.
19. And who knows whether he will be wise or foolish? Yet he will exercise control of all the fruit of my toil with which I toiled wisely under the sun. This also is vanity!
20. So I began to despair of all the toil with which I toiled under the sun.
21. For although a person may toil with great wisdom and skill, he must leave his reward to someone who has not toiled for it. This also is vanity and a great calamity.
22. For what does a person receive for all his toil and in the longing of his heart with which he toils under the sun?
23. All his days are painful, his labor brings grief, and his heart cannot rest at night. This also is vanity!
