Sooner or later in life everyone discovers that perfect happiness is unrealizable, but there are few who pause to consider the antithesis: that perfect unhappiness is equally unattainable. The obstacles preventing the realization of both these extreme states are of the same nature: they derive from our human condition which is opposed to everything infinite.

I live in my house as I live inside my skin: I know more beautiful, more ample, more sturdy and more picturesque skins: but it would seem to me unnatural to exchange them for mine.

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.

The future of humanity is uncertain, even in the most prosperous countries, and the quality of life deteriorates; and yet I believe that what is being discovered about the infinitely large and infinitely small is sufficient to absolve this end of the century and millennium. What a very few are acquiring in knowledge of the physical world will perhaps cause this period not to be judged as a pure return of barbarism.

Even in this place one can survive, and therefore one must want to survive, to tell the story, to bear witness; and that to survive we must force ourselves to save at least the skeleton, the scaffolding, the form of civilization. We are slaves, deprived of every right, exposed to every insult, condemned to certain death, but we still possess one power, and we must defend it with all our strength for it is the last — the power to refuse our consent.

To destroy a man is difficult, almost as difficult as to create one: it has not been easy, nor quick, but you Germans have succeeded. Here we are, docile under your gaze; from our side you have nothing more to fear; no acts of violence, no words of defiance, not even a look of judgment.

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.
