If you look a little further, it seems as if the advantage of wisdom vanishes again. Whether you are wise or foolish, you will all die at some point. This fate befalls every person. People who have died are forgotten – including the people who have lived wisely. The same fate befalls both the wise and the foolish.
15 Et j'ai dit en mon cœur: J'aurai le même sort que l'insensé; pourquoi donc ai-je été plus sage? Et j'ai dit en mon cœur que c'est encore là une vanité.
