For those who have followed my commentaries for a long time, you may realize that I have already commented on this section as we passed through Chapter 18, which is where it appears in the FIP edition, which I was using at the time, before the Circle published the Complete and Annotated Edition (CE). I have essentially duplicated here the commentary I wrote at that time. The Overview has been updated to reflect the new location of the section. I have replaced the quoted text of the section with the same material from the CE, but have compromised by following the paragraphing used in the FIP, to avoid the need to rewrite study questions and comments to accommodate major changes in paragraph breaks. I have taken advantage of the opportunity to do a minor editing pass through my comments, but the changes are minimal.
We'll be studying this section in two or three weeks. Please print yourself a copy if you can.
