But formulas are holy as prayers, decree-laws, and dead languages, and not an iota in them can be changed. And so my ammonium chloride, the twin of a… - Primo Levi

"It is man who kills, man who creates or suffers injustice; it is no longer man who, having lost all restraint, shares his bed with a corpse. Whoever waits for his neighbor to die in order to take his piece of bread is, albeit guiltless, further from the model of
thinking man than the most primitive pigmy or the most vicious sadist".

Se ne potevano trarre due conseguenze filosofiche tra loro contrastanti: l'elogio della purezza, che protegge dal male come un usbergo; l'elogio dell'impurezza, che dà adito ai mutamenti, cioè alla vita. Scartai la prima, disgustosamente moralistica, e mi attardai a considerare la seconda, che mi era più congeniale. Perché la ruota giri, perché la vita viva, ci vogliono le impurezze: anche nel terreno, come è noto, se ha da essere fertile. Ci vuole il diverso, il diverso, il grano di sale e di senape: il fascismo non li vuole, li vieta, e per questo tu non sei fascista; vuole tutti uguali e tu non sei uguale. Ma neppure la virtù immacolata esiste, o se esiste è detestabile

The conviction that life has a purpose is rooted in every fibre of man, it is a property of the human substance. Free men give many names to this purpose, and think and talk a lot about its nature. But for us the question is simpler. Today, in this place, our only purpose is to reach the spring. At the moment we care about nothing else. Behind this aim there is not at the moment any other aim. In the morning while we wait endlessly lined up in roll-call square for the time to leave for work, while every breath of wind penetrates our clothes and runs in violent shivers over our defenceless bodies, and everything is grey around us, and we are grey; in the morning, when it is still dark, we all look at the sky in the east to spot the first signs of a milder season, and the rising of the sun is commented on every day: today a little earlier than yesterday, today a little warmer than yesterday, in two months, in a month, the cold will call a truce and we will have one enemy less. Today the sun rose bright and clear for the first time from the horizon of mud. It is a Polish sun, cold, white, distant, and only warms the skin, but when it dissolved the last mists a murmur ran through our colourless numbers, and when even I felt its lukewarmth through my clothes I understood how men can worship the sun.
