Existentialism

The first chapter of Ecclesiastes shows the dire situation of the man without God--he is stuck in a swamp of vanity. All his work will be destroyed by cyclical natural processes--especially by water and wind. People will forget that he existed. Even if he thinks that he creates something new, someone else will probably have done it first. If a man tries to discover knowledge about natural history, he will fail because there are processes that destroy data which have already destroyed the data which the man is trying to access. Man is only left with the detritus of the past and cannot count what is lacking. It is all very similar to the conclusion of Existentialism.
