Understanding the scapegoat from a Post-modernist Perspective

Girard’s Thought
Picture two young children playing happily on their porch, a pile of toys beside them. The older child pulls a G.I. Joe from the pile and immediately, his younger brother cries out, “No, my toy!”, pushes him out of the way, and grabs it. The older child, who was not very interested in the toy when he picked it up, now conceives a passionate need for it and attempts to wrest it back. Soon a full fight ensues, with the toy forgotten and the two boys busy pummeling each other.
As the fight intensifies, the overweight child next door wanders into their yard and comes up to them, looking for someone to play with. At that point, one of the two rivals looks up and says, “Oh, there’s old fat butt!” “Yeah,” says his brother. “Big fat butt!” The two, having forgotten the toy, now forget their fight and run the child back home. Harmony has been restored between the two brothers, though the neighbor is now indoors crying.
It would not be much of an exaggeration to say that Girard builds his whole theory of human nature and human culture through a close analysis of the dynamics operating in this story. Most human desires are not “original” or spontaneous, he argues, but are created by imitating another whom he calls the “model.” When the model claims an object, that tells another that it is desirable—and that he must have it instead of him. Girard calls this “mimetic” (or imitative) desire. In the subsequent rivalry, the two parties will come to forget the object and will come to desire the conflict for itself. Harmony will only be restored if the conflicting parties can vent their anger on a common enemy or “scapegoat.”
