I address now my readers rather than my muse. You will have noticed I rarely post now. For various reasons, my old habit of writing to my muse through this site no longer works well for me, but I still like this project. So, I have decided to rework the existing material, as well as some notes that never made it in to the blog, and make a book of it. I'll keep you posted about that, and in the meantime I'll probably add new posts here occasionally as I work through my notes.
