As Tony Judt argues persuasively in Reappraisals, we have entered an “age of forgetting.” Today’s world is so utterly unlike the world of just twenty years ago that we have set aside our immediate past even before we could make sense of it. We literally don't know where we came from, and the results of this burgeoning ignorance are proving calamitous, with the clear prospect of worse to come. We have lost touch with three generations of international policy debate, social thought and public-spirited social activism. We no longer know how to discuss such concepts and we have forgotten the role once played by intellectuals in debating, transmitting and defending the ideas that shaped their time. In Reappraisals, Tony Judt resurrects key aspects of the world we have lost and reminds us how important they still are to us: now and to our hopes for the future.
