"Maybe we will have to accept that certain features of the universe are they way they are because of happenstance, accident, or divine choice.  The success of the scientific method in the past has encouraged us to think that with enough time and effort we can unravel nature's mysteries.  But hitting the absolute limit of scientific explanation — not a technical obstacle or the current by progressing edge of human understanding — would be a singular event, one for which past experience could not prepare us."  Brian Greene.  The Elegant Universe.  NY.  Norton.  1999.  385.
