Cosmopolitans begin, I think, with a sense of one thing we all certainly share, which is our fallibility. Nobody has reason to be confident that they're right about everything. That's one of the motivations for conversation across differences. It's in my interest to converse with people who are wrong about different things from the ones I'm wrong about!

We can't literally talk with everybody else on the planet or even with representatives of every group. But we can be in favor of the respectful exchange of ideas in ways that don't presuppose that all the right answers are on our own side. Still, we should all have moral bottom lines. Once genocide or torture begins the priority shifts from understanding to stopping it. One hope I have for the global conversation as instantiated in human rights treaties is that we are slowly coming to consensus on certain moral baselines.

There are many agreements across the so-called "world religions," at a certain level of abstraction. But when it comes to applying them in concrete situations they may lead to incompatible decisions. As an example, some people think that Christian ideas of sexual modesty suggest that homosexuals should be locked up, some people think that they mean that the churches should recongize gay marriages. But everyone believes in sexual modesty. I think there are universal moral truths, whether or not everyone accepts them. Here's one very low level but important one: it's very bad to torture people.

The challenge, then, is to take minds and hearts formed over the long millennia of living in local troops and equip them with ideas and institutions that will allow us to live together as the global tribe we have become.

A value is like a fax machine: it’s not much use if you’re the only one who has one.

If someone hates you, they won't ask you for things.
