As said below, something else was expected of a university, which pushes open doors and revel in platitudes. We're in the world of "There's only" or "We have to." This book taught me nothing and not thinking for two pennies. You can skip 2 or 3 pages, I did often, and it does not interfere with anything playback. An example: p. 24-25-26-, the author lists the "pearls" heard on TV. Why 3 pages? If he wanted a full report, it was at least 30 pages. If it's for examples, 3 or 4 quotes quite sufficient.
