My wife and I are in a childbirth class with a group of about 30 adults, and recently the question of pain came up. One student (apparently a scientist) argued that all pain was indicative of injury—the normal pain of childbirth, even emotional pain and grief involves small tissue damage in the brain. Fascinating! Who knew?
But as I thought about it that night, I found that there was something in the argument that didn’t sit right with me. The next morning I realized what it was: It’s one thing to point out that pain is linked to some kind of cellular rending as a clinical fact, but to claim that all pain is by definition injury is to step out of the magisterium of science and onto my turf—because at that point we are talking about the meanings of words.
The word injury carries with it a strong connotation of wrongness. It comes from the Latin injuria (in = not jus or jur = right, eg justice, jurisprudence). There are some types of pain that don’t feel wrong at all—in fact, they can feel very right. Exercise is one example. I think of the line from Chariots of Fire, when Eric Liddell responds to his sister’s demands that he give up his shot at the Olympics by saying. “God made me for a purpose, but He also made me fast. And when I run, I feel His pleasure.” I wouldn’t call it God, but I certainly have felt an overwhelming sense of rightness in my own running as I push up against the barriers of pain. Injury is an imprecise, misleading word if it describes something that feels right. (NB this is subjective. Running a 60-second 400 meters will be injurious for one person and sublime for another).
