One of concerns

   I am deeply touched by Primo Levi's book. It is not because tragedy in humans history brought me to consider a moment that should not be forgotten, but because I paid an attention to understand characters of human natures. And above all, the writer's extraordinary rational efforts to put into the writing is a vital message about how we ought to live by, even his aim was to report what had really happened in Auschwitz.

   Humans have had a pretty long history of violences toward each others for the sake of survival, and they are not still dead end yet.

   Ultimately, it would stay to last for the last person to be alive on the planet, wouldn't it ?
