This one felt like it would take forever to come out, which isn’t fair since it didn’t take longer than other journal articles or book chapters. But it is an early statement of some of the arguments in the new book (which have evolved since then, naturally). It is also the single article for which I have received the most requests from strangers. And it wasn’t even published until today.
