"But we are here today because we know we cannot be complacent. For history travels not only forwards; history can travel backwards, history can travel sideways. And securing the gains this country has made requires the vigilance of its citizens. Our rights, our freedoms -- they are not given. They must be won. They must be nurtured through struggle and discipline, and persistence and faith. And one concern I have sometimes during these moments, the celebration of the signing of the Civil Rights Act, the March on Washington -- from a distance, sometimes these commemorations seem inevitable, they seem easy. All the pain and difficulty and struggle and doubt -- all that is rubbed away. And we look at ourselves and we say, oh, things are just too different now; we couldn’t possibly do what was done then -- these giants, what they accomplished. And yet, they were men and women, too. It wasn’t easy then. It wasn’t certain then. Still, the story of America is a story of progress. However slow, however incomplete, however harshly challenged at each point on our journey, however flawed our leaders, however many times we have to take a quarter of a loaf or half a loaf -- the story of America is a story of progress. And that’s true because of men like President Lyndon Baines Johnson."
