Time and again, you’ve picked me up. And I hope, sometimes, I picked you up, too. And tonight, I ask you to do for Hillary Clinton what you did for m… - Barack Obama

The one rule that lies at the heart of every major religion is that we do unto others as we would have them do unto us. Adhering to this law of love has always been the core struggle of human nature. For we are fallible. We make mistakes, and fall victim to the temptations of pride, and power, and sometimes evil. Even those of us with the best of intentions will at times fail to right the wrongs before us.

Young people in the audience today, young people like Laura, were born in a place and a time where there is less conflict, more prosperity and more freedom than any time in human history. But that’s not because man’s darkest impulses have vanished. Even here, in Europe, we’ve seen ethnic cleansing in the Balkans that shocked the conscience. The difficulties of integration and globalization, recently amplified by the worst economic crisis of our lifetimes, strained the European project and stirred the rise of a politics that too often targets immigrants or gays or those who seem somehow different. While technology has opened up vast opportunities for trade and innovation and cultural understanding, it’s also allowed terrorists to kill on a horrifying scale. Around the world, sectarian warfare and ethnic conflicts continue to claim thousands of lives. And once again, we are confronted with the belief among some that bigger nations can bully smaller ones to get their way -- that recycled maxim that might somehow makes right. So I come here today to insist that we must never take for granted the progress that has been won here in Europe and advanced around the world, because the contest of ideas continues for your generation. And that’s what’s at stake in Ukraine today. Russia’s leadership is challenging truths that only a few weeks ago seemed self-evident -- that in the 21st century, the borders of Europe cannot be redrawn with force, that international law matters, that people and nations can make their own decisions about their future.

And I think one of the things that's important for bringing about further progress is that we listen to each other and we understand our differences. I don't think it's necessary for us to all speak one language, or all have the same foods, or all have the same customs. But I do believe that there are some universal principles that are important. I believe that the most important principle is a very simple one that is at the heart of most of the world’s great religions, which is treat somebody the same way you’d want to be treated. And if you start with that basic premise, then we will continue to make progress. But I also think that in order for us to make progress, we have to have that fellow feeling and we have to combine that with the use of our brains and reason, and our intellect. […] That requires not just a strong heart, but also using our heads. And if we do those two things, then I feel confident that we'll make progress.
