If I were Donald Trump, I would definitely not pick Mitt Romney because it's very easy for Mitt Romney to have have a separate foreign policy operatus in the State Department that would run a dissenting foreign policy from the White House foreign policy. There, I think the populist America-first foreign policy of Donald Trump does run against a potential rival.

With a normal president like President [Barack] Obama, he says a word, and that's because there has been some thought that he's done and there had been policy papers and there's been aides and there's been advisers and then there is a connection to an actual set of policies. And so, the words like have roots into actual stuff.

Through American history, we have had populist movements that often, often, often have this ugly racial element. But, often, there are warning signs of some deeper social and economic problem.

I don't blame the Democrats for fighting. They have got a very energized base. And there is a lot to complain about a lot of these nominees. But I think, if you are actually going to turn someone down from a president's [Donald Trump] own Cabinet, it better be a lot more egregious than the cases we have seen.

To explain the unknown by the known is a logical procedure; to explain the known by the unknown is a form of theological lunacy.

We have rapidly increasing technology, which is making life very good for people who are good at using words, and not so good for people who are not good at using words.

If you just rely on one model, you tend to amputate reality to make it fit your model.
