Conquering matter is to understand it, and understanding matter is necessary to understanding the universe and ourselves: and that therefore Mendeleev's Periodic Table, which just during those weeks we were learning to unravel, was poetry.

There are few men who know how to go to their deaths with dignity, and often they are not those whom one would expect.

Perhaps one cannot, what is more one must not, understand what happened, because to understand [the Holocaust] is almost to justify...no normal human being will ever be able to identify with Hitler, Himmler, Goebbels, Eichmann, and endless others.

They are non-human words and deeds, really counter-human.

To accuse another of having weak kidneys, lungs, or heart, is not a crime; on the contrary, saying he has a weak brain is a crime.
