"Those who cannot remember the past are condemned to repeat it."
It implies that if we COULD remember the past, we would NOT want to repeat it. ANY of it. And I totally agree.
Everything humanity has done before now has been a failure. Had ANY of it been a success, we would not be in the mess we're in now. Would we?
So I can see why the powers that be are encouraging the destruction of all of our pasts and the promotion of things to come - NEW things which have not been tried before. And the only reason they even tolerate ANY knowledge of the past is to ensure that no one ever does anything like that again.
