Years after Adorno, the Slovenian philosopher Slavoj Žižek proposed that "there can be no genocide without poets", meaning that in order to make people commit atrocities there must always be someone who will train their consciousness and acquire a sublime and noble meaning to violence.
However, it seems that Adorno himself had a different intention in his words, which can be found in another (attributed) quote from him that relates specifically to our relationship to animals. Adorno claims that the sources of human violence are in our exploitative attitude towards animals and therefore he claims that "Auschwitz begins wherever a person looks at a slaughterhouse and thinks to himself: these are just animals."
