People don't want to believe they have to speak like Obama or Clinton to participate meaningfully in politics, because most of us don't speak like Obama or Clinton.

I've always just felt a little out of place. I still feel out of place in San Francisco. It's this place where everything is going great, and everyone feels super optimistic about the world. It's a little different about how I grew up.

I needed a lot of the good things that church provided. But as I grew older, it became increasingly hard for me to rationalize the importance of church in my life with the beliefs that it required that were at odds with modern science.

I have been waiting for someone to come along and tap into that very real frustration that exists in a very large segment of the working-class Republican base. And no one had done it until Donald Trump. I very clearly saw a void, and I knew somebody would fill it. And the moment I knew he had filled it, I knew he would win the nomination.

Politicians of both parties told us that free trade with Asia and Latin America would spur economic growth, and maybe it did somewhere else. In our towns, though, factories continue shutting down or moving overseas.

There are definitely - there is definitely an element of Donald Trump's support that has its basis in racism or xenophobia. But a lot of these folks are just really hardworking people who are struggling in really important ways.

I think running a small nonprofit to work on the opioid crisis and bring interesting new businesses to the so-called Rust Belt - all of these things are valuable, if not more valuable, than running for office.

Undoubtedly, church fish fries and picnics help build social cohesion. It was at my dad's medium-size evangelical church - my first real exposure to a sustained religious community - that I first saw people of different races and classes worshiping together.

Folks like me have to feel a little indebted to the communities that they came from. And if they do, I think we'll start to see a little bit more of a geographic integration in the country because people will start to think, 'You know what? I owe that place something, and I should return to it in one form or another.'

For complicated historical and political reasons, we associate 'poor' in our public consciousness with 'black.' Terms such as 'welfare queen' and 'culture of poverty' became associated uniquely with the social maladies of African Americans in urban ghettos, despite the fact that poor whites outnumbered poor blacks.

We're very good at talking about the individual in American politics and excellent at talking about the government. But we have little ability to even acknowledge everything that exists in the middle, and given how influential politics is on every other part of our life, I think that failure of discourse is pretty corrosive to our overall culture.

Trump's biggest failure as a political leader is that he sees the worst in people, and he encourages the worst in people.

It would be great if people returned to areas of the country that need talented people with good economic prospects. Our country would really benefit if those who went to elite universities, who started businesses, who started nonprofits, weren't just doing so on the coasts.

I used to go on chat rooms on AOL, back when those things existed, and argue with believers in evolution and argued with them that it was against God's law to believe in evolution. It was something I believed really personally.

I have never felt out of place in my entire life. But I did at Yale.

I happen to think that conservatism, when properly applied to the 21st century, could actually help everybody. And the message of Trump's campaign was obviously not super-appealing to Latino Americans, black Americans and so forth. That really bothered me.

When you write a book, and you argue a problem is complicated and multidimensional, it's very easy to read a slice of that book and say, 'Well, this is the part that either confirms or really challenges my biases, so that's what I'm going to say the entire book is about.'

I don't think that the Left has a monopoly on bad ideas. I don't think the Right has a monopoly on good ideas.

Anger about the wars isn't the only reason voters support Mr. Trump. But his willingness to say what other G.O.P. candidates won't reflects what people like most about him: his complete break with the party elite.

We must have the courage to confront dreadful views even in the people we love the most. But that's difficult to do when we cast large segments of our fellow citizens into a basket to be condemned and disparaged, judging them even as we ignore that many of their deplorable traits exist in us, too.

The military is arguably the most significant social institution in our country.

I do think that tonal element of Trump's is attractive, but I don't know if I would go so far as to say the confrontational element of his rhetoric is necessarily attractive.

The most depressing part of the 2016 election is that the candidates often failed to show any cultural leadership: any recognition that the world of public policy was important but hardly the only good and necessary part of our shared society.

For decades, scholars have studied the ways in which implicit biases affect how we perceive other people in this multiethnic society of ours. The data consistently shows that about 90 percent of us possess some implicit prejudices - and, unsurprisingly, people typically favor their own group.
