Our Struggle for Immorality.

I watched the Ted Talk about the four stories we tell ourselves about death by Stephen Cave. Stephen talks about how death plays an extreme role in society throughout history and how we as humans come up with stories about immorality to escape the constant fear of death. The four stories he mentions are elixir, resurrection, soul, and legacy, which are all ideas humanity has relied on to believe that they will live forever in some way or another. Stephen states that when humanity realizes not to fear death but except it and not to rely on these four stories we can truly progress a create a "good story" without worrying about the "end of our book" or death. Stephen reasoning behind this is that humanity has constantly been repeating itself by creating new ways to keep the four stories about immorality alive which has stalled the actual progression of our race. The one thing that i don't agree with is that the human race will want to progress knowing they will eventually die. How do we know that because of this realization we won't just stop trying to progress thinking its not worth anything because we are going to die someday? Is it certain that everyone will want to make the best of there life span and create a "good life story" knowing that you might just be forgotten about in a couple years? I believe that we will never know until this realization occurs if it ever does.
