In one way or another, human desire has always indicated that something is lacking. My stomach is empty so I desire to fill it with food. I don’t have as much money as I would like for the necessities and treats I want so I feel empty until I get enough money to get them. I lack the satisfaction of seeing my favorite baseball team win unless they win. If they do win, I am back to square one with the same emptiness and the same desire by the next day.

René Girard’s theory of mimetic desire pushes the lack that leads to desire a step further. We don’t just lack possessions or a girlfriend; we don’t know what food or what girl to desire until we see what food and what girl somebody else desires. As we learn from scientists’ study of our mirror neurons, we don’t necessarily desire what other people want because they want it or we think they want it. Rather our desires automatically resonate with the desires of others and we need to learn to navigate these resonances as part of human maturation. This prevents us from automatically copying every desire we see in others but the less conscious we are of the impact others’ desires have on us, the more likely we will be driven by others’ desires and the more empty we will be as a result.

Those desires of ours that are drawn from other people easily become conflictual. When that happens, the emptiness opened by mimetic desire deepens into an abyss. When we are wrapped up with a rival, it is never enough to have what the rival wants. As Girard points out, we need to become the other person. We believe (wrongly) that the other person has a certain fullness of being that we don’t have because they have—or seem to have—what we want but don’t have. So it is that we covet not just the ox or wife or car of another but the very being of another person. This is why we never have enough money or possessions or anything else as long as we are in rivalrous relationships. For Girard, this is not an ontological statement but an anthropological one. That is, it is about human relationships. The problem is that we can covet the being of another person until the end of the world and we’ll come up empty. Since the alleged fullness of being on the part of another is illusory, we are only “chasing after wind” (Eccl. 1:14).

Christian thinkers have consistently averred that we are instilled with a longing for God as a gift from God and that this longing means that we cannot be totally satisfied with anything else, no matter how wonderful. As the Psalmist says: our souls “thirst for the living God” (Psa. 42: 2).If we see mimetic desire as fundamental to humanity, it follows that this trait is willed by God and used by God in a fundamental way for our salvation. The certain lack of being caused by mimetic desire gives us an ongoing openness to God, an opening for God to enter into us and dwell within us as Jesus promised us in John’s Gospel. We are created to resonate with the desires of others so that we can resonate with the Desire of the other Other. The phrase “cdeep calls from deep: (Psa. 42: 7) has often been interpreted as the depths of our humanity crying out to the depths of God. This depth is our desire resonating mimetically with God’s Desire. While it is an illusion to think that a human rival has a plenitude of being, God really does have such plenitude. Moreover, God is infinitely generous with God’s plenitude of being. If we open ourselves to God’s Desire, we participate in that Desire is such a way that we can be equally generous with others.
