Indiscriminate ideological suspicion of any idea, without the urge to exalt an idea of one's own, will discourage rather than promote lucidity.

The Left’s identity politics poses a threat to free speech and to the kind of rational discourse needed to sustain a democracy... The focus on lived experience by identity groups prioritizes the emotional world of the inner self over the rational examination of issues in the outside world and privileges sincerely held opinions over a process of reasoned deliberation that may force one to abandon prior opinions.

What I worry about is that the truth doesn't matter, and I think this is something that has changed from 20 years ago, it's not just that the truth doesn't matter anymore, it's that it doesn't matter that the truth doesn't matter anymore. [...] I also think that people really do want some kind of an honest assessment of things that are important. Of something grounded in fact. I think that is something that is actually necessary for a liberal democracy to function.

What’s at stake in this debate goes far beyond a few months of headlines, or passing tensions in our foreign policy. When you cut through the noise, what’s really at stake is how we remain true to who we are in a world that is remaking itself at dizzying speed. Whether it’s the ability of individuals to communicate ideas; to access information that would have once filled every great library in every country in the world; or to forge bonds with people on other sides of the globe, technology is remaking what is possible for individuals, and for institutions, and for the international order. So while the reforms that I have announced will point us in a new direction, I am mindful that more work will be needed in the future. One thing I’m certain of: This debate will make us stronger. And I also know that in this time of change, the United States of America will have to lead. It may seem sometimes that America is being held to a different standard. And I'll admit the readiness of some to assume the worst motives by our government can be frustrating. No one expects China to have an open debate about their surveillance programs, or Russia to take privacy concerns of citizens in other places into account. But let’s remember: We are held to a different standard precisely because we have been at the forefront of defending personal privacy and human dignity.

The problem is that this kind of vilification and over-the-top rhetoric closes the door to the possibility of compromise. It undermines democratic deliberation. It prevents learning –- since, after all, why should we listen to a “fascist,” or a “socialist,” or a “right-wing nut,” or a left-wing nut”?

It makes it nearly impossible for people who have legitimate but bridgeable differences to sit down at the same table and hash things out. It robs us of a rational and serious debate, the one we need to have about the very real and very big challenges facing this nation. It coarsens our culture, and at its worst, it can send signals to the most extreme elements of our society that perhaps violence is a justifiable response.

So what do we do? As I found out after a year in the White House, changing this type of politics is not easy. And part of what civility requires is that we recall the simple lesson most of us learned from our parents: Treat others as you would like to be treated, with courtesy and respect. (Applause.) But civility in this age also requires something more than just asking if we can’t just all get along.
