“Since Auschwitz we know what man is capable of. And since Hiroshima we know what is at stake.”

“So, let us be alert--alert in a twofold sense.Since Auschwitz we know what man is capable of. And since Hiroshima we know what is at stake.”

“Our generation is realistic, for we have come to know man as he really is. After all, man is that being who invented the gas chambers of Auschwitz; however, he is also that being who entered those gas chambers upright, with the Lord's Prayer or the Shema Yisrael on his lips.”

“Was Du erlebst, kann keine Macht der Welt Dir rauben. (What you have experienced, no power on earth can take from you.) Not only our experiences, but all we have done, whatever great thoughts we may have had and all we have suffered, all this is not lost, though it is past; we have brought it into being. Having been is a kind of being, and perhaps the surest kind.”

“Sigmund Freud once asserted, "Let one attempt to expose a number of the most diverse people uniformly to hunger. With the increase of the imperative urge of hunger all individual differences will blur, and in their stead will appear the uniform expression of the one unstilled urge." Thank heaven, Sigmund Freud was spared knowing the concentration camps from the inside. His subjects lay on a couch designed in the plush style of Victorian culture, not in the filth of Auschwitz. There, the "individual differences" did not "blur" but, on the contrary, people became more different; people unmasked themselves, both the swine and the saints.”

“A human being is not one thing among others; things determine each other, but man is ultimately self-determining. What he becomes - within the limits of endowment and environment- he has made out of himself. In the concentration camps, for example, in this living laboratory and on this testing ground, we watched and witnessed some of our comrades behave like swine while others behaved like saints. Man has both potentialities within himself; which one is actualized depends on decisions but not on conditions.”

“Long ago we had passed the stage of asking what was the meaning of life, a naïve query which understands life as the attaining of some aim through the active creation of something of value.”
