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.

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.

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.

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.

Those who expect moments of change to be comfortable and free of conflict have not learned their history.

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.

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.
