“Does a wise man answer with blustery knowledge, or fill his belly with the east wind?

The wise man can see where he is going, but the fool walks in darkness. Yet I also realized that the same fate happens to them both.

For the wise man, like the fool, will not be remembered for very long, because in the days to come, both will already have been forgotten. Alas, the wise man dies – just like the fool!

Who knows if he will be a wise man or a fool? Yet he will be master over all the fruit of my labor for which I worked so wisely on earth! This also is futile!

I said, “Who is wise enough to understand why this has happened? Who has a word from the Lord that can explain it? Why does the land lie in ruins? Why is it as scorched as a desert through which no one travels?”

then I discerned all that God has done: No one really comprehends what happens on earth. Despite all human efforts to discover it, no one can ever grasp it. Even if a wise person claimed that he understood, he would not really comprehend it.
