Today I think that if for no other reason than that an Auschwitz existed, no one in our age should speak of Providence.

It is neither easy nor agreeable to dredge this abyss of viciousness, and yet I think it must be done, because what could be perpetrated yesterday could be attempted again tomorrow, could overwhelm us and our children. One is tempted to turn away with a grimace and close one's mind: this is a temptation one must resist. In fact, the existence of the death squads had a meaning, a message: 'We, the master race, are your destroyers, but you are no better than we are; if we so wish, and we do so wish, we can destroy not only your bodies, but also your souls, just as we have destroyed ours.

Man is a centaur, a tangle of flesh and mind, divine inspiration and dust.

If you and your child were going to be killed tomorrow, would you not give him to eat today?

Auschwitz is outside of us, but it is all around us, in the air. The plague has died away, but the infection still lingers and it would be foolish to deny it. Rejection of human solidarity, obtuse and cynical indifference to the suffering of others, abdication of the intellect and of moral sense to the principle of authority, and above all, at the root of everything, a sweeping tide of cowardice, a colossal cowardice which masks itself as warring virtue, love of country and faith in an idea.

Monsters exist, but they are too few in numbers to be truly dangerous. More dangerous are…the functionaries ready to believe and act without asking questions.

For me chemistry represented an indefinite cloud of future potentialities which enveloped my life to come in black volutes torn by fiery flashes, like those which had hidden Mount Sinai. Like Moses, from that cloud I expected my law, the principle of order in me, around me, and in the world... I would watch the buds swell in spring, the mica glint in the granite, my own hands, and I would say to myself: "I will understand this, too, I will understand everything.
