So...in addition to writing the Penguin book, there is also of course the Verso book. It's really interesting to be writing two at once. I don't think I've ever quite done it before. They are on two really distinct missions, these books. One is designed to show you that you can incorporate nonhumans into Marxism. The other is super IMAX widescreen 3D ecological philosophy.
(Not that the Verso topic isn't vast as well!)
I stared writing the Verso one, Humankind, this afternoon. Apparently I really do have something to say, as I reached my goal for the day.
The Verso book is in five through-composed shorter chapters. The sequence definitely goes 1 >> 2 >> 3 etc. There's a logical sequence that would be really out of shape if the book's arrangement didn't track it.
The Penguin book is a little different. Each chapter feels modular. You could probably have them in any order, although I think the one I chose is best. The inner logic and the arrangement don't coincide, quite.
That's an interesting, less well known fact about the five parts of rhetoric, Aristotle style. You've got your second part, which is called ordo in Latin. But it's also called dispositio. The latter is the arrangement of the idea sequence. The former is the logical sequence. You see the difference?
When you're thinking how a book should be, what you want to say is actually different from when you want to say it, and both are really important.
The ordo-dispositio mix for each book feels really right. It's nice to be doing them together for that reason. They are different beasts. Maybe the beasts will synergize one another, at this rhetorical level. I know they will at other levels...
I'll be interesting to see what kinds of style differences emerge as I proceed (the third part of rhetoric).
