Each time we gather to inaugurate a President we bear witness to the enduring strength of our Constitution. We affirm the promise of our democracy. W… - Barack Obama

We know a history so that we can learn from it. We learn our history because we understand the sacrifices that were made before, so that when we make sacrifices we understand we're doing it on behalf of future generations. There’s a proverb that says, “We have not inherited this land from our forebears, we have borrowed it from our children.” In other words, we study the past so it can guide us into the future, and inspire us to do better.

For us, for our children, Africa and its people teach us a powerful lesson -- that we must uphold the inherent dignity of every human being. Dignity -- that basic idea that by virtue of our common humanity, no matter where we come from, or what we look like, we are all born equal, touched by the grace of God. Every person has worth. Every person matters. Every person deserves to be treated with decency and respect. Throughout much of history, mankind did not see this. Dignity was seen as a virtue reserved to those of rank and privilege, kings and elders. It took a revolution of the spirit, over many centuries, to open our eyes to the dignity of every person. And around the world, generations have struggled to put this idea into practice in laws and in institutions.

The world that America seeks is not one we can build on our own. For human rights to reach those who suffer the boot of oppression, we need your voices to speak out. In particular, I appeal to those nations who emerged from tyranny and inspired the world in the second half of the last century, from South Africa to South Asia, from Eastern Europe to South America. Don't stand idly by, don't be silent when dissidents elsewhere are imprisoned and protesters are beaten. Recall your own history, because part of the price of our own freedom is standing up for the freedom of others.
