“There are two styles of walls "opus reticulatum," now used by everybody and the ancient style called "opus incertum." Of these, the reticulatum looks better, but its construction makes it likely to crack… On the other hand, in the opus incertum, the rubble lying in courses and imbricated, makes a wall which though not beautiful, is stronger.”

Context: The wall belongs to history. But we have history to make as well. And the heroes that came before us now call to us to live up to those highest ideals -- to care for the young people who can't find a job in our own countries, and the girls who aren't allowed to go to school overseas; to be vigilant in safeguarding our own freedoms, but also to extend a hand to those who are reaching for freedom abroad. This is the lesson of the ages. This is the spirit of Berlin. And the greatest tribute that we can pay to those who came before us is by carrying on their work to pursue peace and justice not only in our countries but for all mankind.
