Stephen Pinker, transcribed by edge.org:
The literary scholars Mark Turner and Francis-Noël Thomas have identified the stance that our best essayists and writers implicitly adopt, and that is a combination of vision and conversation. When you write you should pretend that you, the writer, see something in the world that’s interesting, that you are directing the attention of your reader to that thing in the world, and that you are doing so by means of conversation.
That may sound obvious. But it’s amazing how many of the bad habits of academese and legalese and so on come from flouting that model. Bad writers don’t point to something in the world but areself-conscious about not seeming naïve about the pitfalls of their own enterprise. Their goal is not to show something to the reader but to prove that they are nota bad lawyer or a bad scientist or a bad academic. And so bad writing is cluttered with apologies and hedges and “somewhats” and reviews of the past activity of people in the same line of work as the writer, as opposed to concentrating on something in the world that the writer is trying to get someone else to see with their own eyes.
