The thing about education - and why I'm so passionate about the position and status of the university - is that it's supposed to teach citizens how to think better, how to think critically, how to tell truth from falsehood, how to make a judgment about when they're being lied to and duped and when they're not, how to evaluate scientific teaching. Losing that training of citizens is an extremely dangerous road to go down.

The reason you go to university is to be taught, is to learn how to think more clearly, to call into question the ideas that you came with and think about whether or not they are the ideas you will always want to hold. A university education at its best is a time of confusion and questioning, a time to learn how to think clearly about the values and principles that guide one's life. Of course, it's also a time to acquire the skills needed for jobs in the "real world," but the part about becoming an adult with ideals and integrity is also important.

I think what is being pointed out by African-Americans is that from slavery forward they have been living in a supposed democracy which treats them as less than other citizens, less than whites in the society. And I think that pointing out that there are structures of discrimination in the society, deeply rooted racist structures, that segregate housing, that send black children to ill-equipped schools, that discriminate in the workplace - these are truths about our society that must be faced.

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.

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.

Richard Hofstadter, in his famous book which was written in the time of the McCarthy period in the 1950 and 1960s, Anti-intellectualism in American Life, talks about the deep hatred that some Americans had for what they consider to be elitist intellectual activity. I think that's what's happening now.

The university is the place where the pursuit of truth is taught, the rules for learning how to pursue it are explained, and students begin to understand how to evaluate the seriousness of truth. Those are incredibly important lessons, and only the teachers' academic freedom can protect them because there will always be people who disagree with or disapprove of the ideas they are trying to convey.
