An importance beyond that which words may convey
One howls with frustration that this book might not be universally accessible; louder yet, since its being a work of philosophy might be the least of the reasons why that is.
For the spirit in which it was conceived and which clearly inspires and leaks from every word is pretty much lost to the world today---that of Humanity, rendered incoherent by what latterly counts as commonsense. This I reckon accounts for the epidemic of Rawls-misreading; indeed it is not unknown for him to even be misread as saying what he *so* was not (think accusing Richard Dawkins of pious Catholicism)--a difference, all told, of competing concepts. He lost; now think of the problems we face today: as urgent as they are seemingly intractable.
So, 'recommend' doesn't come close, but with one proviso: please read it as if you've never before encountered the words 'politics', 'society', 'person', 'justice', 'fairness', 'cooperation', 'liberal*', and 'democracy'---let him convey with his conceptions of these a world of possibilities for our world.
