Just a note to say I may not be able to pick up and return to things I've started to explore on here, particularly when they require a lot of preparation and research. I've entered university again, and it's making some demands on my time. I think it's worthwhile still to put down a kind of placeholder for things to be thought. Then when I have time again, I can return to the work.
The other thing I should note is that school requires me to be on a laptop for much of the day, and computer screens often give me a headache. So that's limiting my writing on the blog.
