I did not read Philosophy: Principles and Problems, or rather, I did read it. It turns out, it is just a reprint of The Intelligent Person’s Guide to Philosophy.
The main difference is that the conservative, more or less intellectually-minded imprint, Bloomsbury, changed the title. My guess is to make it sound less populist and more… I don’t know. High-minded.
Whatever. I got from the library in an orgy of Roger Scruton borrowing, so I guess, not much lost. Perhaps even a net benefit because I might have gained some small amount of muscle from carrying it home. Not much though. It’s an even smaller book in this edition.
