Did chemistry theorems exist? No: therefore you had to go further, not be satisfied with the quia, go back to the origins, to mathematics and physics. The origins of chemistry were ignoble, or at least equivocal: the dens of the alchemists, their abominable hodgepodge of ideas and language, their confessed interest in gold, their Levantine swindles typical of charlatans and magicians; instead, at the origin of physics lay the strenuous clarity of the West-Archimedes and Euclid.

Dawn came on us like a betrayer; it seemed as though the new sun rose as an ally of our enemies to assist in our destruction.

We who survived the Camps are not true witnesses. We are those who, through prevarication, skill or luck, never touched bottom. Those who have, and who have seen the face of the Gorgon, did not return, or returned wordless.

We must be listened to: above and beyond our personal experience, we have collectively witnessed a fundamental unexpected event, fundamental precisely because unexpected, not foreseen by anyone. It happened, therefore it can happen again: this is the core of what we have to say. It can happen, and it can happen everywhere.

We will not return No one must leave here and so carry to the world, together with the sign impressed on his skin, the evil tidings of what man's presumption made of man in Auschwitz

I'm a libertine, but it's not my specialty.

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. This dismays us, and at the same time gives us a sense of relief, because perhaps it is desirable that their words (and also, unfortunately, their deeds) cannot be comprehensible to us. They are non-human words and deeds, really counter-human.
