I am at a loss how you could list Dawkins as "good science writing". In my opinion, Dawkins is one of the worst things that could happen to intelligent atheism. I have never heard or read him say anything remotely interesting to the intelligent theist. Dawkins apparently thinks "theism" equals "stupid theism" and does a great job debunking variants of theism that are vastly inferior to himself in terms of intellect. Afaik he has so far shown no sign that he even understands intelligent theism. This has had the effect on countless of intelligent people to think that theism is stupid, and you only need to be a little rational to see that. In other words, rhetorics of the Dawkins kind makes sure that the debate that should he had does not take place. In my book, this is not rhetorics "for good". Such has been the impact of Dawkins that I seriously wonder how many of the self-described atheists on this site have ever even stopped to consider the point of view of intelligent theists. In my opinion, as long as you haven't considered or understood intelligent theists, you have no right calling yourself an atheist ("hur, hur, talking snake" is not a refutation of theism).
Failing to organize a wall of text into paragraphs does not hide the lack of relationship between its first sentence and every other sentence, nor that no sentence other than the first addressed anything relevant to the issue under discussion. The origin of the name "Vermont" is uncertain, but likely comes from the French les Verts Monts, meaning "the Green Mountains". Thomas Young introduced it in 1777. Some authorities say that the mountains were called green because they were more forested than the higher White Mountains of New Hamps...
The topics of rationality and existential risk reduction need their own Richard Dawkins. Their own Darwin. Their own Voltaire.
Rhetoric moves minds.
Students and masochists aside, people read only what is exciting. So: Want to make an impact? Be exciting. You must be heard before you can turn heads in the right direction.
Thus, I've decided to try harder and actually put effort into the quality of my writing instead of just cranking stuff out quickly so I can fill in inferential gaps and get to the cutting edge of the research subjects I care about.
That's why I asked LWers for their picks of best nonfiction writing on Less Wrong.
It's also why I've been reading lots of good science writing, focusing on those who manage to be exciting while covering fairly complex subjects: Dawkins, Sagan, Gleick, Zimmer, Shermer, Ramachandran, Roach, Sacks, Hawking, Greene, Hofstadter, Penrose, Wilson, Feynman, Kaku, Gould, Bryson, Pinker, Kurzban, and others.
I've also been re-reading lots of books and articles on how to write well: Keys to Great Writing, Style: Lessons in Clarity and Grace, Elements of Style, On Writing Well, The Classic Guide to Better Writing, The Book on Writing, Telling True Stories, Writing Tools, Ideas into Words, The Chicago Guide to Communicating Science, A Field Guide for Science Writers, Six Rules for Rewriting, Writing, Briefly, and Singularity Writing Advice. (Conversations with Eliezer also helped.)
I don't know if I can become the Voltaire of rationality and existential risk reduction, but it seems worth a shot. Every improvement in writing style is beneficial even if my starry goal is never met. Also, it appears I produce better writing without really trying than most people produce with trying. (If you've ever had to grade essays by honors English seniors, you'll know what I mean.) I expect to gain more by striving where I already excel than by pushing where I have little natural talent.
(I won't try to write everything well. Sometimes I should just crank things out. To be honest, I didn't spend much time optimizing this post.)
My other hope is that a few other writers decide they would like to be the Voltaire of rationality and/or existential risk reduction. May this post be useful to them. It's a list of recommendations on writing style pulled from many sources, in no particular order.
And, just one piece of process advice. Do not apply any of these rules while drafting. Instead, write down whatever horrible shit comes out of you and do it quickly. Then revise, revise, revise.
Now: What are your favorite pieces of writing advice?
