Another sobering thought is that basically all memory of our existence will be lost within 3 or 4 generations of our death.
I've often thought of this too. Take graveyards for instance, which ones get the most visits? Usually only the most recent. After 50-100 years most family will have moved away or have forgotten the direct link they used to have with their departed relative. Family that is usually more then four generations never get too meet in person due to age refines, so the deceased ones fading memory carry's a lack of importance.
I liked the thought of certain passages pherhaps being added to Ecclesiastes at a later date. This is speculation but could certainly be probable. Was Solomon re-evaluating his very belief on mortality? He certainly was coming to a realization of lifes short journey.
