In particular, Girard was interested in the causes of conflict and violence and the role of imitation in human behavior. Our desires, he wrote, are not our own; we want what others want. These duplicated desires lead to rivalry and violence. He argued that human conflict was not caused by our differences, but rather by our sameness. Individuals and societies offload blame and culpability onto an outsider, a scapegoat, whose elimination reconciles antagonists and restores unity.
