Augustine holds ignorance to be a primary source of human enmity

Evidence

Ignorance, ignorantia, is what “leads men to believe an enemy to be a friend, or a friend an enemy” (19.8). Friendship is thus mixed with fear, which often turns into murderous desires. Hence, we fear that our friends’ affection “be changed into treachery, malice and baseness,” but “certainly we would rather hear that our friends were dead” (ibid.). — Gil Anidjar, The Jew, the Arab, 158
