Krista's Journal: Science That Liberates Us from Reductive Analyses

May 24, 2012

I first began to gain a kind of respect for the revenge impulse in human life when we worked, in the early days of this program, on a show about the death penalty. I came to understand that revenge was the original "criminal justice system." For most of human history, prior to the rule of law, prior to structures of justice that transcend the messiness of human interaction, the threat of retaliation has been a primary tool humans possessed to pursue justice and also to deter cycles of violence. I'll never forget Sister Helen Prejean, a great campaigner against the death penalty, The Last Words of Texas' Death Row Inmatsdescribing anger as a moral response. The question, of course, is where we let that anger take us.

Now, as Michael McCullough lays out passionately, science is able to document how normal, and purposeful, our instinct for revenge is. In the brain, the instinct for revenge looks like a "craving," a felt need that begs for satiation. We do range into the realms of global geopolitics in this conversation — to the world around Joseph Kony in Uganda no less — Michael McCullough is just as interested in the mundane forms this craving takes: in our reactions to neighbors and irritating co-workers or to our political opposites.

The good news is that Michael McCullough's research is also revealing that forgiveness is hard-wired in us — purposeful and normal. He says that to think of forgiveness as a trait of the weak and the vulnerable reflects a simplistic imagination about evolutionary biology. We tolerate and excuse the deficits and mistakes of those we know and love and work with — Grocery store parking lotand even those we don't love but need to work with — many times each day. Forgiveness doesn't work in real life as it too often works in media portrayals of dramatic stories of conversion and high emotion. It happens constantly, and we rarely stop to glorify it with the lofty word "forgiveness."

This science, in other words, liberates us from reductive analyses of ourselves and the world around us. If we accept the normalcy of our instincts both to revenge and forgive, and can see what triggers them both, we have more control over both.

On its cautionary side, it offers lucid explanation of why human societies remain vulnerable — physiologically, not merely politically — to falling back on retaliation and violence as a form of justice. When we cease to see our own well-being as linked to that of others, when we feel threatened by their very existence and are only able to see them amorphously as part of an opposing group, the forgiveness instinct becomes less possible and violence more likely.

This conversation with Michael McCullough heightens my sense of what is at stake in the present global and national moment. One the one hand, the interactivity of the globalized world should make it possible — even necessary — for us to know people far beyond our families and "tribes" as necessary to our survival and even our flourishing.

I am also deeply concerned, as we roll through another toxic election year, at how complete the chasms in American society have become. We have divided ourselves in countless ways — between red and blue, between the 99 percent and the 1 percent. Such distinctions are surely inevitable. But the utter lack of communication, courtesy, and curiosity across these divides seems new to me. Alarmingly, the religious traditions that have been humanity's moral respositories are also implicated in some of these divisions. How intriguing to imagine that we might harness lessons of science towards a more reconciliatory, peacable future.
