We borrow our desires from others. Far from being autonomous, our desire for a certain object is always provoked by the desire of another person — the model — for this same object. This means that the relationship between the subject and the object is not direct: there is always a triangular relationship of subject, model, and object. Through the object, one is drawn to the model, whom Girard calls the mediator: it is in fact the model who is sought. Girard calls desire "metaphysical" in the measure that, as soon as a desire is something more than a simple need or appetite, "all desire is a desire to be",[9] it is an aspiration, the dream of a fullness attributed to the mediator.

Since the mimetic rivalry that develops from the struggle for the possession of the objects is contagious, it leads to the threat of violence. Girard himself says, "If there is a normal order in societies, it must be the fruit of an anterior crisis."[10] Turning his interest towards the anthropological domain, Girard began to study anthropological literature and proposed his second great hypothesis: the victimization process, which is at the origin of archaic religion and which he sets forth in his second book Violence and the Sacred (1972).

If two individuals desire the same thing, there will soon be a third, then a fourth. This process quickly snowballs. Since from the beginning the desire is aroused by the other (and not by the object) the object is soon forgotten and the mimetic conflict transforms into a general antagonism. At this stage of the crisis the antagonists will no longer imitate each other's desires for an object, but each other's antagonism. They wanted to share the same object, but now they want to destroy the same enemy. So, a paroxysm of violence would tend to focus on an arbitrary victim and a unanimous antipathy would, mimetically, grow against him. The brutal elimination of the victim would reduce the appetite for violence that possessed everyone a moment before, and leaves the group suddenly appeased and calm. The victim lies before the group, appearing simultaneously as the origin of the crisis and as the one responsible for this miracle of renewed peace. He becomes sacred, that is to say the bearer of the prodigious power of defusing the crisis and bringing peace back. Girard believes this to be the genesis of archaic religion, of ritual sacrifice as the repetition of the original event, of myth as an account of this event, of the taboos that forbid access to all the objects at the origin of the rivalries that degenerated into this absolutely traumatizing crisis. This religious elaboration takes place gradually over the course of the repetition of the mimetic crises whose resolution brings only a temporary peace. The elaboration of the rites and of the taboos constitutes a kind of empirical knowledge about violence.

Although explorers and anthropologists have not been able to witness events similar to these, which go back to the earliest times, indirect evidence for them abounds, such as the universality of ritual sacrifice and the innumerable myths that have been collected from the most varied peoples. If Girard's theory is true, then we will find in myths the culpability of the victim-god, depictions of the selection of the victim, and his power to beget the order that governs the group. Girard found these elements in numerous myths, beginning with that of Oedipus, which he analyzed in this and later books. On this question he opposes Claude Lévi-Strauss.

The phrase "scapegoat mechanism" was not coined by Girard himself; it had been used earlier by Kenneth Burke in Permanence and Change (1935) and A Grammar of Motives (1940). However, Girard took this concept from Burke and developed it much more extensively as an interpretation of human culture.

In Things Hidden Since the Foundation of the World (1978), Girard develops the implications of this discovery. The victimary process is the missing link between the animal world and the human world, the principle that explains the humanization of primates. It allows us to understand the need for sacrificial victims, which in turn explains the hunt which is primitively ritual, and the domestication of animals as a fortuitous result of the acclimatization of a reserve of victims, or agriculture. It shows that at the beginning of all culture is archaic religion, which Durkheim had sensed.[11] The elaboration of the rites and taboos by proto-human or human groups would take infinitely varied forms while obeying a rigorous practical sense that we can detect: the prevention of the return of the mimetic crisis. So we can find in archaic religion the origin of all political or cultural institutions.

According to Girard, just as the theory of natural selection of species is the rational principle that explains the immense diversity of forms of life, the victimization process is the rational principle that explains the origin of the infinite diversity of cultural forms. The analogy with Darwin also extends to the scientific status of the theory, as each of these presents itself as a hypothesis that is not capable of being proven experimentally, given the extreme amounts of time necessary to the production of the phenomena in question, but which imposes itself by its great explanatory power.

In Things Hidden Since the Foundation of the World, Girard discusses for the first time Christianity and the Bible. The Gospels ostensibly present themselves as a typical mythical account, with a victim-god lynched by a unanimous crowd, an event that is then commemorated by Christians through ritual sacrifice — a material re-presentation in this case — in the Eucharist. The parallel is perfect except for one detail: the truth of the innocence of the victim is proclaimed by the text and the writer. The mythical account is usually built on the lie of the guilt of the victim inasmuch as it is an account of the event seen from the viewpoint of the anonymous lynchers. This ignorance is indispensable to the efficacy of the sacrificial violence.

The evangelical "good news" clearly affirms the innocence of the victim, thus becoming, by attacking ignorance, the germ of the destruction of the sacrificial order on which rests the equilibrium of societies. Already the Old Testament shows this turning inside-out of the mythic accounts with regard to the innocence of the victims (Abel, Joseph, Job, ...), and the Hebrews were conscious of the uniqueness of their religious tradition. With the Gospels, it is with full clarity that are unveiled these "things hidden since the foundation of the world" (Matthew 13:35), the foundation of social order on murder, described in all its repulsive ugliness in the account of the Passion.

This revelation is even clearer because the text is a work on desire and violence, from the serpent setting alight the desire of Eve in paradise to the prodigious strength of the mimetism that brings about the denial of Peter during the Passion (Mark 14: 66-72; Luke 22:54-62). Girard reinterprets certain biblical expressions in light of his theories; for instance, he sees "scandal" (skandalon, literally, a "snare", or an "impediment placed in the way and causing one to stumble or fall"[15]) as signifying mimetic rivalry, for example Peter's denial of Jesus.[16] No one escapes responsibility, neither the envious nor the envied: "Woe to the man through whom scandal comes" (Matthew 18:7).

Girard’s fundamental concept is ‘mimetic desire’. Ever since Plato, students of human nature have highlighted the great mimetic capacity of human beings; that is, we are the species most apt at imitation. Indeed, imitation is the basic mechanism of learning (we learn inasmuch as we imitate what our teachers do), and neuroscientists are increasingly reporting that our neural structure promotes imitation very proficiently (for example, ‘mirror neurons’).

However, according to Girard, most thinking devoted to imitation pays little attention to the fact that we also imitate other people’s desires, and depending on how this happens, it may lead to conflicts and rivalries. If people imitate each other’s desires, they may wind up desiring the very same things; and if they desire the same things, they may easily become rivals, as they reach for the same objects. Girard usually distinguishes ‘imitation’ from ‘mimesis’. The former is usually understood as the positive aspect of reproducing someone else’s behavior, whereas the latter usually implies the negative aspect of rivalry. It should also be mentioned that because the former usually is understood to refer to mimicry, Girard proposes the latter term to refer to the deeper, instinctive response that humans have to each other.

In Girard’s psychology, internal mediation and metaphysical desire eventually lead to rivalry and violence. Imitation eventually erases the differences among human beings, and inasmuch as people become similar to each other, they desire the same things, which leads to rivalries and a Hobbesian war of all against all. These rivalries soon bear the potential to threaten the very existence of communities. Thus, Girard asks: how is it possible for communities to overcome their internal strife?

Whereas the philosophers of the 18th century would have agreed that communal violence comes to an end due to a social contract, Girard believes that, paradoxically, the problem of violence is frequently solved with a lesser dose of violence. When mimetic rivalries accuмulate, tensions grow ever greater. But, that tension eventually reaches a paroxysm. When violence is at the point of threatening the existence of the community, very frequently a bizarre psychosocial mechanism arises: communal violence is all of the sudden projected upon a single individual. Thus, people that were formerly struggling, now unite efforts against someone chosen as a scapegoat. Former enemies now become friends, as they communally participate in the execution of violence against a specified enemy.

Girard calls this process ‘scapegoating’, an allusion to the ancient religious ritual where communal sins were metaphorically imposed upon a he-goat, and this beast was eventually abandoned in the desert, or sacrificed to the gods (in the Hebrew Bible, this is especially prescribed in Leviticus 16).The person that receives the communal violence is a ‘scapegoat’ in this sense: her death or expulsion is useful as a regeneration of communal peace and restoration of relationships.

However, Girard considers it crucial that this process be unconscious in order to work. The victim must never be recognized as an innocent scapegoat (indeed, Girard considers that, prior to the rise of Christianity, ‘innocent scapegoat’ was virtually an oxymoron; see section 4.b below); rather, the victim must be thought of as a monstrous creature that transgressed some prohibition and deserved to be punished. In such a manner, the community deceives itself into believing that the victim is the culprit of the communal crisis, and that the elimination of the victim will eventually restore peace.

Girard believes that the scapegoat mechanism is the very foundation of cultural life. Natural man became civilized, not through some sort of rational deliberation embodied in a social contract, (as it was fashionable to think among 18th century philosophers) but rather, through the repetition of the scapegoat mechanism. And, very much as many philosophers of the 18th Century believed that their descriptions of the natural state were in fact historical, Girard believes that, indeed, Paleolithic men continually used the scapegoat mechanism, and it was precisely this feature what allowed them to lay the foundations of culture and civilization.

In fact, Girard believes that this process goes farther back in the evolution of Homo sapiens: hominids probably were engaged in scapegoating. But, it was precisely scapegoating what allowed a minimum of communal peace among early hominid groups. Hominids could eventually develop their main cultural traits due to the efficiency of the scapegoat mechanism. The murder of a victim brought forth communal peace, and this peace promoted the flourishing of the most basic cultural institutions.

Once again, Girard takes deep inspiration from Freud, but reinterprets his observations. Freud’s Totem and Taboo presents a thesis that the origins of culture are founded upon the original murder of a father figure by his sons. Girard considers that Freud’s observations were only partially correct. Freud is right in pointing out that indeed, culture is founded upon a murder. But, this murder is not due to the oedipal themes Freud was so fond of. Instead, the founding murder is due to the scapegoat mechanism. The horde murdered a victim (not necessarily a father figure) in order to project upon her all the violence that was threatening the very existence of the community.

However, as mimetic desire has been a constant among human beings, scapegoating has never been entirely efficient. Nevertheless, human communities need to periodically recourse to the scapegoating mechanism in order to maintain social peace.

According to Girard, the scapegoat mechanism brings about unexpected peace. But, this moment is so marvelous, that it soon acquires a religious overtone. Thus, the victim is immediately consecrated. Girard is in the French sociological tradition of Durkheim, who considered that religion essentially accomplishes the function of social integration. In Girard’s view, inasmuch as the deceased victim brings forth communal peace and restores social order and integration, she becomes sacred.

At first, while living, victims are considered to be monstrous transgressors that deserve to be punished. But, once they die, they bring peace to the community. Then, they are not monsters any longer, but rather gods. Girard highlights that, in most primitive societies, there is a deep ambivalence towards deities: they hold high virtues, but they are also capable of performing some very monstrous deeds. That is how, according to Girard, primitive gods are sanctified victims.

In such a manner, all cultures are founded upon a religious basis. The function of the sacred is to offer protection for the stability of communal peace. And, to do this, it ensures that the scapegoat mechanism provides its effects through the main religious institutions.

Girard considers rituals the earliest cultural and religious institution. In Girard’s view, ritual is a reenactment of the original scapegoating murder. Although, as anthropologists are quick to assert, rituals are very diverse, Girard considers that the most popular form of ritual is sacrifice. When a victim is ritually killed, Girard believes, the community is commemorating the original event that promoted peace.

The original victim was most likely a member of the community. Girard considers that, probably, earliest sacrificial rituals employed human victims. Thus, Aztec human sacrifice may have impacted Western conquistadors and missionaries upon its discovery, but this was a cultural remnant of a popular ancient practice. Eventually, rituals promoted sacrificial substitution, and animals were employed. In fact, Girard considers that hunting and the domestication of animals arose out of the need to continually reenact the original murder with substitute animal victims.

Following the old school of European anthropologists, Girard believes that myths are the narrative corollary of ritual. And, inasmuch as rituals are mainly a reenactment of the original murder, myths also recapitulate the scapegoating themes.

Now, Girard’s crucial point about the necessary unconsciousness of scapegoating: must be kept in mind in order for this mechanism to work, its participants must not recognize it as such. That is to say, the victim must never appear as what it really is: a scapegoat that is no guiltier of disturbance, than other members of the community.

The way to assure that scapegoats are not recognized as what they really are is by distorting the story of the events that led to their death. This is accomplished by telling the story from the perspective of the scapegoaters. Myths will usually tell a story of someone doing a terrible thing and, thus, deserving to be punished. The victim’s perspective will never be incorporated into the myth, precisely because this would spoil the psychological effect of the scapegoating mechanism. The victim will always be portrayed as a culprit whose deeds brought about social chaos, but whose death or expulsion brought about social peace.

Girard’s Christian apologetics departs from a comparison of myths and the Bible. According to Girard, whereas myths are caught under the dynamics of the scapegoat mechanism by telling the foundational stories from the perspective of the scapegoaters, the Bible contains plenty of stories that tell the story from the perspective of the victims.

In myths, those who are collectively executed are presented as monstrous culprits that deserve to be punished. In the Bible, those who are collectively executed are presented as innocent victims that are unfairly accused and persecuted. Thus, Girard recapitulates the old Christian apologetic tradition of insisting upon the Bible’s singularity. But, instead of making emphasis on the Bible’s popularity, or fulfillment of prophecies, or consistency, Girard thinks the Bible is unique in its defense of victims.

However, according to Girard, this is not merely a shift in narrative perspective. It is in fact something much more profound. Inasmuch as the Bible presents stories from the perspective of the victims, the Biblical authors reveal something not understood by previous mythological traditions. And, by doing so, they make scapegoating inoperative. Once scapegoats are recognized for what they truly are, the scapegoating mechanism no longer works. Thus, the Bible is a remarkably subversive text, inasmuch as it shatters the scapegoating foundations of culture.

Under Girard’s interpretation, the New Testament is the completion of the process that the Hebrew Bible had begun. The New Testament fully endorses the victims’ perspective, and satisfactorily dissociates the sacred from the violent.

The Passion story is central in the New Testament, and it is the complete reversal of traditional myth’s structure. Amidst a huge social crisis, a victim (Jesus) is persecuted, blamed of some fault, and executed. Even the apostles succuмb to the collective pressure and abandon Jesus, tacitly becoming part of the scapegoating crowd. This is emblematic in the story of Peter’s denial of Jesus.

Nevertheless, the evangelists never succuмb to the collective pressure of the scapegoating mob. The evangelists adhere to Jesus’ innocence throughout the whole story. Alas, Jesus is finally recognized as what he really is: an innocent scapegoat, the Lamb of God that was taken to the slaughterhouse, although no fault was in him. According to Girard, this is the completion of a slow process begun in the Hebrew Bible. Once and for all, the New Testament reverses the violent psychosocial mechanism upon which human culture has been founded.

Aside from that, Jesus’ ethical message is complementary. Under Girard’s interpretation, humanity has achieved social peace by performing violent acts of scapegoating. Jesus’ solution is much more radical and efficient: to turn the other cheek, to abstain from violent retribution. Scapegoating is not an efficient means to bring about peace, as it always depends on the periodic repetition of the mechanism. The real solution is in the total withdrawal from violence, and that is the bulk of Jesus’ message.

Girard acknowledges that, on the surface, not everything in the New Testament is about peace and love. Indeed, there are some frightening passages in Jesus’ preaching, perhaps the most emblematic “I come not to bring peace, but a sword”. This is part of the apocalyptic worldview prevalent in Jesus’ days. But, much more than that, Girard believes that the apocalyptic teachings to be found in the New Testament are a warning about future human violence.

Girard considers that, inasmuch as the New Testament overturns the old scapegoating practices, humanity no longer has the capacity to return to the scapegoating mechanism in order to restore peace. Once victims are revealed as innocent, scapegoating can no longer be relied upon to restore peace. And, in such a sense, there is now an even greater threat of violence. According to Girard, Jesus brings a sword, not in the sense that he himself is going to execute violence, but in the sense that, through his work and the influence of the Bible, humanity will not have the traditional violent means to put an end to violence. The inefficacy of the scapegoat mechanism will bring even more violence. The way to restore peace is not through the scapegoat mechanism, but rather, through the total withdrawal of violence.

Thus, Girard believes that, ironically, Christianity has brought about even more violence. But, once again, this violence is not attributable to Christianity itself, but rather, to the stubbornness of human beings who do not want to follow the Christian admonition and insist on putting an end to violence through traditional scapegoating.

Girard believes that, 20th and 21st centuries are more than ever an apocalyptic age. And, once again, he acknowledges a 19th century German figure as a precursor of these views: Carl von Clausewitz. According to Girard, the great Prussian war strategist realized that modern war would no longer be an honorable enterprise, but rather, a brutal activity that has the potential to destroy all of humanity. Indeed, Girard believes 20th and 21st centuries are apocalyptic, but not in the fundamentalist sense. The ‘signs’ of apocalypse are not numerical clues such as 666, but rather, signs that humanity has not found an efficient way to put an end to violence, and unless the Christian message of repentance and withdrawal from violence is assumed, we are headed towards doomsday; not a Final Judgment brought forth by a punishing God, but rather, a doomsday brought about by our own human violence.

Furthermore, the doctrine of Incarnation becomes especially important under Girard’s interpretation. For God himself incarnates in the person of Jesus, in order to become himself a victim. Thus, God is so far removed from aggressors and scapegoaters, He himself becomes a victim in order to show humanity that He sides with innocent victims. Thus, the way to overturn the scapegoat mechanism is not only by telling the stories from the perspective of the victim, but also by telling the story that the victim itself is God incarnate.
