The aims of life are the best defense against death. — Primo Levi

It was not possible for us nor did we want to become islands; the just (i giusti) among us, neither more nor less numerous than in any other human group, felt remorse, shame and pain for the misdeeds that others and not they had committed, and in which they felt involved, because they sensed that what had happened around them and in their presence, and in them, was irrevocable. Never again could it be cleansed; it would prove that man, the human species — we, in short — had the potential to construct an enormity of pain, and that pain is the only force created from nothing, without cost and without effort. It is enough not to see, not to listen, not to act.

The prisoners who saved themselves were not the best, the predestined to good, the bearers of a message: what I had seen and experienced showed the exact opposite. Survived the worst of preference, the selfish, the violent, the insensitive, the collaborators of the 'gray area', the spies. It was not a certain rule (there were, nor are there in human affairs, certain rules), but was also a rule. I felt so innocent, but trooped among the saved, and therefore constantly looking for an excuse, before me and the others. Survived the worst, that is the most suitable; the best are all dead.

In countries and epochs in which communication is impeded, soon all other liberties wither; discussion dies by inanition, ignorance of the opinion of others becomes rampant, imposed opinions triumph. The well-known example of this is the crazy genetics preached in the USSR by Lysenko, which in the absence of discussion (his opponents were exiled to Siberia) compromised the harvests for twenty years. Intolerance is inclined to censor, and censorship promotes ignorance of the arguments of others and thus intolerance itself: a rigid, vicious circle that is hard to break.
