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

The phrase 'academic freedom' is often used carelessly: here is a work that will allow a more careful conversation about those many crucial issues facing the academy, in which a well-worked out understanding of conceptions of academic freedom is, as its authors show, an essential tool.

Unless you have the power to stop the government of Iran beheading teenagers for homosexual acts, there's not much to be done except deplore it unless you are willing to converse with people about why they thinking this is okay.

One of the central challenges for global conversation today is to find ways of getting to understand very different views about gender and sexuality. But we should start by recognizing that these issues are subjct to disputation within every society as well as across societies. We need a global conversation that recognizes that we have these very different views. Next, try to agree on fundamental rights: things we think every person is entitled to. Finally, if we're convinced that what a government or a society elsewhere is doing to some people is badly wrong and the conversation gets nowhere.

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.

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.

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.
