There are students whose religious upbringing is going to make them feel uncomfortable in a class where certain kinds of secular ideas are presented. There are students whose ideas about history or sexuality are going to be similarly challenged to question, to affirm or to change those ideas. That doesn't mean they shouldn't be exposed to them; that's why they're at school. That's why they come to university: to be taught how to think well and critically about material that they're being presented with. But it's the teacher who is certified to teach them how to do that.

If the students don't want to learn about evolution, they shouldn't be in the course. A biology course that teaches creationism is not a science course, it's a religion course. So the students demanding that creationism be given credence in that course are out of line and are denying the academic freedom of the professor. They are calling into question the scientific basis of the material that's being presented. And students are not in a position to do that.

What I mean by the common good is that we understand we're all part of something bigger than ourselves, that we live in societies together and must help take care of one another because you never know when you're going to need to be taken care of by others. And it's not enough to say that your family or your church is going to take care of you. Societies are collective entities, we're meant to be connected to one another; the function of government is to administer that connection.

I don't think colleges are safe spaces. It's one thing to have a fraternity house or a community center where students can go and talk about their shared experiences. But it's another thing to have safe spaces in the sense that the university's providing them with protection from what they have to experience and find ways of protesting and resisting.

There's actually a wonderful quote from Stanley Fish, who is sometimes very polemical and with whom I don't always agree. He writes, "Freedom of speech is not an academic value. Accuracy of speech is an academic value; completeness of speech is an academic value; relevance of speech is an academic value. Each of these is directly related to the goal of academic inquiry: getting a matter of fact right."

The internet has made possible a frightening practice of threats and intimidation - threats of unspeakable violence and death.
