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."

Free speech is what we all have and is guaranteed by the First Amendment of the US Constitution. Academic freedom refers to what happens in the university, particularly in the classroom, and to the importance of the teacher having the right to teach and share what he or she has learned, has proven her competence to teach, having gone through a series of tests and certifications including research and writing to demonstrate her abilities and knowledge.

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

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.

We've increasingly lost that sense of community, of the notion that there is something we contribute to and benefit from that is called the common good.

We've increasingly lost that sense of community, of the notion that there is something we contribute to and benefit from that is called the common good. I think I would date the beginnings of that loss to the Reagan administration and to the notion that somehow we were all separate individuals who only ought to be interested in ourselves.
