Excerpt from Primo Levi's 'The Drowned and The Saved', a collection of essays depicting his time at the Concentration (extermination) camps :-
'I too entered the Lager as a nonbeliever, and as a nonbeliever I was liberated and have lived to this day. Actually, the experience of the Lager with its frightful iniquity confirmed me in my non-belief. It has prevented me, and still prevents me, from conceiving of any form of providence or transcendant justice… I must nevertheless admit that I experienced (and again only once) the temptation to yield, to seek refuge in prayer. This happened in October 1944, in the one moment in which I lucidly perceived the imminence of death… naked and compressed among my naked companions with my personal index card in hand, I was waiting to file past the ‘commission’ that with one glance would decide whether I should go immediately into the gas chamber or was instead strong enough to go on working. For one instance I felt the need to ask for help and asylum; then, despite my anguish, equanimity prevailed: one does not change the rules of the game at the end of the match, nor when you are losing. A prayer under these conditions would have been not only absurd (what rights could I claim? and from whom?) but blasphemous, obscene, laden with the greatest impiety of which a nonbeliever is capable.
I rejected the temptation: I knew that otherwise were I to survive, I would have to be ashamed of it.'
