What is the power of historical perspective? How can we learn from the past to reform our society of the future? The late historian Tony Judt reframed the history of the European continent after WWII in his book Postwar. A luminous thinker, he clarified the power of historical perspective for living even ordinary lives. In this final book, written with Timothy Snyder, he traverses the complexities of the twentieth century and guides us through the great debates that made our world.
