I had mixed feelings towards this book. For starters, I assume that it is targeted to people who want to get familiarised with the topic... Nonetheless, that is also my main concern. The authors set up a theory that, being all philosophically imaginative and wit, is psychologically inert. C'mon! Most of PoL seems like a rebranding of already well-established theories in Social Psychology -including Group Psychology, Persuasion Psychology, etc-. Don't get me wrong -- I have no problem with re-thinking or borrowing frameworks from other disciplines; however, I feel that it is being assigned another name or presented as a genuinely new theoretical framework for contributions that are already somewhat like the missal of Social Psychology (or, at times, some ideas that were once very vibrant but are now relatively outdated). They propose and address "new" problems that arise only when theories in psychology are examined superficially. This could have been a valuable rehearsal of these theories in connection to their philosophical takes! Sadly, I believe that this idea was not executed correctly.
