Hitchens' cancer has gone after his vocal cords. His voice is on the fritz, which inspired him to write about its place in his life and writing:
To my writing classes I used … to open by saying that anybody who could talk could also write. Having cheered them up with this easy-to-grasp ladder, I then replaced it with a huge and loathsome snake: “How many people in this class, would you say, can talk? I mean really talk?” That had its duly woeful effect. I told them to read every composition aloud, preferably to a trusted friend. The rules are much the same: Avoid stock expressions (like the plague, as William Safire used to say) and repetitions. Don’t say that as a boy your grandmother used to read to you, unless at that stage of her life she really was a boy, in which case you have probably thrown away a better intro. If something is worth hearing or listening to, it’s very probably worth reading. So, this above all: Find your own voice.
