For good or evil, we are a single people: the more we become conscious of this, the less difficult and long will be humanity’s progress toward justic… - Primo Levi

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 was fed up with books, which I still continued to gulp down with indiscreet voracity, and searched for a key to the highest truths; there must be a key, and I was certain that, owing to some monstrous conspiracy to my detriment and the world's, I would not get in school. In school they loaded with me with tons of notions that I diligently digested, but which did not warm the blood in my veins. 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, but not the way they want me to. I will find a shortcut, I will make a lock-pick, I will push open the doors."
It was enervating, nauseating, to listen to lectures on the problem of being and knowing, when everything around us was a mystery pressing to be revealed: the old wood of the benches, the sun's sphere beyond the windowpanes and the roofs, the vain flight of the pappus down in the June air. Would all the philosophers and all the armies of the world be able to construct this little fly? No, nor even understand it: this was a shame and an abomination, another road must be found.

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.

Tutti scoprono, più o meno presto nella loro vita, che la felicità perfetta non è realizzabile, ma pochi si soffermano invece sulla considerazione opposta: che tale è anche una infelicità perfetta. I momenti che si oppongono alla realizzazione di entrambi i due stati-limite sono della stessa natura: conseguono dalla nostra condizione umana, che è nemica di ogni infinito.
Vi si oppone la nostra sempre insufficiente conoscenza del futuro; e questo si chiama, in un caso, speranza, e nell'altro, incertezza del domani. Vi si oppone la sicurezza della morte, che impone un limite a ogni gioia, ma anche a ogni dolore. Vi si oppongono le inevitabili cure materiali, che, come inquinano ogni felicità duratura, cosi distolgono assiduamente la nostra attenzione dalla sventura che ci sovrasta, e ne rendono frammentaria, e perciò sostenibile, la consapevolezza.
Sono stati proprio i disagi, le percosse, il freddo, la sete, che ci hanno tenuti a galla sul vuoto di una disperazione senza fondo, durante il viaggio e dopo.
