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 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.

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

The growing gap between rich and poor, the seeming lack of concern for the health and well-being of ordinary people, the obscene salaries made by CEOs who are increasing profits by moving their plants to places where labor is cheap - that's where the problem is, not in schools, colleges and universities.

I think the anger that is being directed to universities and so-called elites at universities is actually an anger that's displaced from politicians (who promise to make things better and never do), from employers, it's an anger at the economic system that has put so many of these people out of the kind of work that once was so satisfying to them.

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.
