When history looks back I want people to know the Nazis weren't able to kill millions of people and get away with it.

Technology without hatred can be a blessing. Technology with hatred is always a disaster.

There is no denying that Hitler and Stalin are alive today... they are waiting for us to forget, because this is what makes possible the resurrection of these two monsters.

Even before I had had time to really think things through, I realized we must not forget. If all of us forgot, the same thing might happen again, in 20 or 50 or 100 years.

I know I am not only the bad conscience of the Nazis. I am also the bad conscience of the Jews. Because what I have taken up as my duty was everybody's duty.

Discovering witnesses is just as important as catching criminals.

The combination of hatred and technology is the greatest danger threatening mankind.
