Where the world ceases to be the stage     
  for personal hopes and desires, where we, 
     as free beings, behold it in wonder,   
      to question and to contemplate,       
       there we enter the realm of art and  
        science. If we trace out what we    
         behold and experience through the  
         language of logic, we are doing    
         science; if we show it in forms    
         whose interrelationships are not   
        accessible to our conscious thought 
       but are intuitively recognized as    
      meaningful, we are doing art. Common  
     to both is the devotion to something   
    beyond the personal, removed from       
  the arbitrary.                            
                  --  A.  Einstein.
