"We came from Caladan - a paradise world for our form of life. There existed no need on Caladan to build a physical paradise or a paradise of the mind - we could see the actuality all around us. And the price we paid was the price men have always paid for achieving a paradise in this life - we went soft, we lost our edge." - Muad'Dib, Conversations - Dune (Frank Herbert)

....... "where there is no vision the people perish."
