Freedom of speech is about expressing your opinion, however bad or good, however right or wrong, and being able to defend it and argue it and be argued with about it in public forums. But that's not what academic freedom is about. That's not what the classroom is about.

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.

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.

The Trump election brought it the fore and made it possible for a number of different groups whose aim is to stop the teaching of critical thinking to to launch direct attacks.

I think there is a disrespect for the mind that Trump, for example, exemplifies. His is a kind of strategic thinking that's more about shrewdness than about intellect. His attack on "elites" is meant to rally his base to rebel against the powers that be - in Washington especially. I don't think he cares much about higher education per se; he just wants to demonstrate that learning isn't necessary for business or government. He wants to elevate mediocrity to a heroic virtue.

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.
