Alan Jacobs relays what he learned from reading aloud an essay he was working on:
As I was reading, as my mind was processing words and sending them along to my lips and larynx, a word pricked my conscience; I scanned my word-hoard for alternatives, and managed to retrieve one, to my relief. But it’s not always so easy. A few minutes later in the same lecture I came across a whole phrase that, even as it was about to emerge into the public air for the first time, was revealed to me as fundamentally uncharitable — but because it was a whole phrase I did not have time to construct an alternative. I was therefore forced to utter words even as I was renouncing them, to be convicted out of my own mouth of a lack of generosity. I was made to own, by speaking them, words I wished I had not written.
His broader point about the ethics of writing:
[M]any have been my idle words over the years. I wonder how much harm they have done to others, and even to me. I did not publish my first book until I was nearly 40, and while I used to regret that late start, I now am thankful that I didn’t get the chance earlier in life to pour forth yet more sentences to spend my latter years regretting.
A handful of times over the years I have drafted essays only to realize, before submitting them, that I did not want to say what I had written there; and a few other times I have had cause to thank editors for rejecting pieces that, had they been published, would have brought me embarrassment later.
In some cases the embarrassment would have been because of arguments badly made or paragraphs awkwardly formed; but in others because of a simple lack of charity or grace. An essay begins with an idea, but an idea begins with a certain orientation of the mind and will — with a mood, if you please. We have only the ideas that our mood of the moment prepares us to have, and while our moods may be connected to the truth of things, they are normally connected only to some truths, some highly partial facet of reality. Out of that mood we think; out of those thoughts we write. And it may be that only in speaking those thoughts do we discern the mood from which they arose. “Out of the abundance of the heart the mouth speaks” — a terrifying judgment, when you think of it.
