"I did not intend, nor would I have been able, to do a historian's work, that is, exhaustively examine the sources. I have almost exclusively confined myself to the National Socialist Lagers (camps) because I had direct experience only of these; I also have had copious indirect experience of them through books read, stories listened to, and encounters with the readers of my first two books. Besides, up to the moment of this writing, and notwithstanding the horror of Hiroshima and Nagasaki, the shame of the Gulags, the useless and bloody Vietnam War, the Cambodian self-genocide, the desaparecidos of Argentina, and the many atrocious and stupid wars we have seen since, the Nazi concentration camp system still remains a unicum, both in its extent and its quality. At no other place or time has one seen a phenomenon so unexpected and so complex: never have so many human lives been extinguished in so short a time, and with so lucid a combination of technological ingenuity, fanaticism, and cruelty." From The Drowned and the Saved by Primo Levi (p21).
