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 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.

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 common good is the notion of shared collective responsibility and reciprocity. It's that that we've lost.

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.

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 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.
