So, we all face the same end, and our hearts are naturally inclined towards wrong. What's the ultimate outcome of this life lived this way?
The Finality of Death
Verse 3 concludes with a stark reminder: 'and after that they go to the dead.' This isn't just about the physical burial; it speaks to the end of their conscious experience in this world. The Teacher is emphasizing that all the striving, all the 'madness,' all the pursuit of fleeting pleasures, ultimately leads to the same cessation of life.
A Call to Wisdom
While this passage can sound pessimistic, it's actually a powerful call to live differently. Recognizing the common fate and the corruption of the heart is precisely why the Teacher elsewhere urges wisdom. If life on earth is fleeting and its outcomes can seem unfair, then true wisdom lies in fearing God and keeping His commandments, finding meaning and purpose in Him rather than in the transient things of the world.
