Humble Brains

As the most social of all species - equipped with highly sensitive social antennea, complex ommunication skills and team work ability, it is surprising that we spend so much time on screwing eachother over.  As if individual greed ever persevered against the common good.  Check out history - it works for a generation or two, maybe.  But then it's back to the drawing board.  Seems to me rocket science is not what we need.  Common sense is.
