I was correcting my (many lazy and stupid and regrettable) mistakes, thankfully pointed out by YOS, in the soul posting and hit the wrong button. I seem to have lost everything (which is just as well), including the valuable corrections YOS made in comments (which is unfortunate).
Meanwhile, read this on souls.
Update Thanks to the readers who received the old post by email and who have gave me copies. When I get back, I’ll edit them. Thanks!
