"The most striking among Milgram's findings is the inverse ratio of readiness to cruelty and proximity to its victim. It is difficult to harm a person we touch. It is somewhat easier to afflict pain upon a person we only see at a distance. It is still easier in the case of a person we only hear. It is quite easy to be cruel towards a person we neither see nor hear."
- Zygmunt Bauman in Modernity and the Holocaust
