A little milestone today: I have completed a draft of the introduction. Big deal, it’s just 9 pages. I found it quite difficult to write because it needs to connect to a variety of readers and to motivate the book’s content, while basing itself on previous work. Many revisions are in its future. But I’ll gladly accept any comments any of you have on it to make it better.
