I have not read the book yet.
Based on Paul's article, most of the good advices by Jack Bogle are nothing new to people come to this site.
I took a note on Jack's current view on international stocks. While he is still defending a US-only equity portfolio, looks like his current view on international stocks changed a little from the previous edition.
Looking forward to reading the new book soon.However, Bogle admits that “perhaps the relative advantage achieved in the U.S. stock market over the past quarter-century has now been arbitraged away” and that international stocks may be relative bargains.
