we believe in human progress  we create the servants we need  we develop new ways of living  we develop new ways of living  we search for power sources  we need energy to survive  we build on fragile ground  we build on fragile ground  we feel safe in our unstable houses  we fear the world outside  we've become strangers at home  we've become strangers at home  we went too far, we can't turn back  we built too high, we can't get down  we are the slaves of our servants  in the shadow of our ambitions
