Many moons ago, when I was in college, I had to take what they called a “writing course”, which was a class designed specifically to teach writing, but about subjects in our chosen major. (Mine was Econ.) I think the point was to prevent a bunch of mathematics geniuses from taking over the field with equations and graphs strung together by incoherent babble.
It doesn’t seem to have worked.
Anyway, the section I was in was unpopular, because the professor assigned not one, not two, not three, but four books. Now, they were all short books, and one of them (The Ghost Map) actually became one of my favorites. But that’s not the one I want to talk about here. I want to talk about the first one we had to read: The Doctors’ Plague.
The book is about Ignaz Semmelweis, a Hungarian doctor who, in the 1840s, tried to reduce the so-called “childbed fever” then prevalent in the hospital where he worked. Germ theory was not widely understood at the time, and Semmelweis’s radical proposal was that doctors and nurses who treated infants and mothers should wash their hands.
This sounds absurdly obvious to us modern readers, but at the time it was heretical, and indeed, Semmelweis wasn’t taken seriously by the medical establishment. Whether due to his difficult temper, some unknown mental disorder, or possibly a language barrier, Semmelweis failed to prevail upon the medical community to adopt hand-washing as a regular practice. He died in an insane asylum, and his work was not recognized until long after his death.
Naturally, we Econ students were all puzzled by this. (Those of us that read it, that is. I suspect a quarter of the class just looked up the book’s synopsis online, and another quarter didn’t even do that.) What on God’s Green Earth does this have to do with Supply and Demand?
After the week or whatever our allotted time to read the book was, the professor started the class by giving his summary of the book–I assume for the benefit of the ones who didn’t read it. He finished up by raising the question we were asking ourselves: why did he assign this?
The point of the book, he said, was that Semmelweis couldn’t communicate his ideas to his colleagues. “So,” he concluded, “You have to learn to write well! It doesn’t matter if you discover something great if no one can understand you.”
I think he intended this as a carpe diem moment, but most of the class felt like they’d just been told the world’s longest shaggy dog story. But he was right; you do have to be able to write well, no matter how good your underlying point is.
I’m not even sure if that was really the main lesson of the Semmelweis story, but nevertheless, it’s true. And regardless of whether writing well has anything to do with Semmelweis or not, the professor created a helpful mnemonic: writing well is as important as good hygiene in a hospital.
