You unlock this door with the key of imagination. Beyond it is another dimension: a dimension of sound, a dimension of sight, a dimension of mind. Yo… - Rod Serling

It's simply a national acknowledgement that in any kind of priority, the needs of human beings must come first. Poverty is here and now. Hunger is here and now. Racial tension is here and now. Pollution is here and now. These are the things that scream for a response. And if we don't listen to that scream - and if we don't respond to it - we may well wind up sitting amidst our own rubble, looking for the truck that hit us - or the bomb that pulverized us. Get the license number of whatever it was that destroyed the dream. And I think we will find that the vehicle was registered in our own name.

There is an answer to the doctor's question. All the Dachaus must remain standing. The Dachaus, the Belsens, the Buchenwald, the Auschwitzes – all of them. They must remain standing because they are a monument to a moment in time when some men decided to turn the Earth into a graveyard. Into it they shoveled all of their reason, their logic, their knowledge, but worst of all, their conscience. And the moment we forget this, the moment we cease to be haunted by its remembrance, then we become the gravediggers. Something to dwell on and to remember, not only in the Twilight Zone but wherever men walk God's Earth.

Every man is put on earth condemned to die. Time and method of execution unknown.
