Alongside the liberating relief of the veteran who tells us his story, I now felt in the writing a complex, intense, and new pleasure, similar to that I felt as a student when penetrating the solemn order of differentials calculus. It was exalting to search and find, or create, the right word, that is, commensurate, concise, and strong; to dredge up events from my memory and describe them with the greatest rigor and the least clutter.

An extreme case of the distortion of the memory of a committed guilty act is found in its suppression. Here, too, the borderline between good and bad faith can be vague; behind the "I don't know" and "I do not remember" that one hears in courtrooms there is sometimes the precise intent to lie, but at other times it is a fossilized lie, signified in a formula.

Compassion and brutality can coexist in the same individual and in the same moment...

For human nature is such that grief and pain - even simultaneously suffered - do not add up as a whole in our consciousness, but hide, the lesser behind the greater, according to a definite law of perspective. It is providential and is our means of surviving in the camp. And this is the reason why so often in free life one hears it said that man is never content.

He was a physicist, more precisely an astrophysicist, diligent and eager but without illusions: the Truth lay beyond, inaccessible to our telescopes, accessible to the initiates. This was a long road which he was traveling with effort, wonderment, and profound joy. Physics was prose: elegant gymnastics for the mind, mirror of Creation, the key to man's dominion over the planet; but what is the stature of Creation, of man and the planet? His road was long, and he had barely started up it, but I was his disciple: did I want to follow him?

Human memory is a marvelous but fallacious instrument. The memories which lie within us are not carved in stone; not only do they tend to become erased as the years go by, but often they change, or even increase by incorporating extraneous features.

I am constantly amazed by man's inhumanity to man.

If we had to and were able to suffer the sufferings of everyone, we could not live.

... In our days many men have lived in this cruel manner, crushed against the bottom, but each for a relatively short period; so that we can perhaps ask ourselves if it is necessary or good to retain any memory of this exceptional human state. To this question we feel that we have to reply in the affirmative. We are in fact convinced that no human experience is without meaning or unworthy of analysis, and that fundamental values, even if they are not positive, can be deduced from this particular world which we are describing…

It is lucky that it is not windy today. Strange, how in some way one always has the impression of being fortunate, how some chance happening perhaps infinitesimal, stops us crossing the threshold of despair and allows us to live. It is raining, but it is not windy.
