During the First World War, the anthropologist Bronislaw Malinowski had a conversation with a tribesman in Papua New Guinea who practiced cannibalism.
The cannibal asked Malinowski how the Europeans could possibly be managing to eat the millions of people being killed in the war.
Malinowski replied that they did not eat them at all, as such a practice was neither customary nor acceptable.
The cannibal was shocked, remarking that the Europeans must be barbaric to kill so many people without any intention of eating them. What was the point of all that slaughter?
