It is a pretty structure isn’t it? It makes you think of something solid, stable, well-linked. In fact it… — Primo Levi

Sandro was surprised when I tried to explain to him some of the ideas that at the time I was confusedly cultivating. That the nobility of man, acquired in a hundred centuries of trial and error, lay in making himself the conquerer of matter, and that I had enrolled in chemistry because I wanted to remain faithful to this nobility. That conquering matter is to understand it, and understanding matter is necessary to understanding the universe and ourselves: and that therefore Mendeleev's Periodic Table, which just during those weeks we were laboriously learning to unravel, was poetry, loftier and more solemn than all the poetry we had swallowed down in liceo; and come to think of it, it even rhymed!

Distilling is beautiful. First of all because it is a slow, philosophic, and silent occupation, which keeps you busy but gives you time to think of other things, somewhat like riding a bike. Then, because it involves a metamorphosis from liquid to vapor (invisible), and from this once again to liquid; but in this double journey, up and down, purity is obtained, an ambiguous and fascinating condition, which starts with chemistry and goes very far. And finally, when you set about distilling, you acquire the consciousness of repeating a ritual consecrated by the centuries, almost a religious act, in which from imperfect material you obtain the essence, the ussia, the spirit, and in the first place alcohol, which gladdens the spirit and warms the heart.

I was a chemist in a chemical plant... and I stole in order to eat. If you do not begin as a child, learning how to steal is not easy; it had taken me several months before I could repress the moral commandments and acquired the necessary techniques... I stole everything except the bread of my companions. ...There was a mysterious jar ...It contained ...gray, hard, colorless, odorless, tasteless little rods and did not have a label ...[T]he Russians were a few kilometers away ..; everybody knew the war was about to end: but finally some constants must still subsist, and among them were our hunger ...Alberto took a penknife ...He tried to scrape it ...and saw a spray of yellow sparks ...it was iron-cerium ...from which common flints of cigarette lighters are made. ...Alberto ...explained ...they were mounted on the tips of oxyacetylene torches to ignite the flame. ...Alberto ...did not accept the concentration camp universe ...and miraculously he had remained free ...he had not bowed his head ...I has stolen the : good ...he would turn it into ...an article of high commercial value. Prometheus had been foolish to bestow fire... instead of selling it... the price of a lighter flint was equivalent to a ration of bread... one day of life. ...[I]n two months cerium would have liberated us, an element about which I knew nothing, save ...that it belongs to the equivocal and heretical rare-earth ...family, and that its name has nothing to do with the ...word for wax (cera) and ...it celebrates ...the asteroid Ceres, since the metal and the star were discovered in the same year ...an affectionate-ironic homage to alchemical couplings: just as the Sun was gold and Mars iron, so Ceres must be cerium.
