Anytime students shout down a speaker who says something different, this is not good.

You'll remember Newton was furious at Leibniz, because he developed calculus at the same time. And he went to his death believing that he had copied him. And no, it's because all the elements were there, so it's almost inevitable that the next discovery - as long as people are free and allowed to experiment and try new things.

All of our policies are based on whether it will make - enable people to improve their lives or it will make their lives worse.

Hubris, arrogance, is just one step ahead of loss of integrity, because if you think you're better than other people, you know more, then you're going to think, as many leaders have, that the rules don't apply to them - so they lose their integrity.

Putting aside all the things that are said about Hillary [Clinton], my main difference with her is on the vision of what kind of society will make people's lives better. So this is a vision of society in which people are too evil or stupid to run their own lives, but those in power are perfectly capable of running everybody else's lives because they're so much smarter.

I don't like the idea of capitalism anyway. Because it's not capital we are talking about; it's knowledge and creating well-being. Because I mean, that gets people on the wrong track when it's capital and how we allocate capital - no. How do we create the Republic of Science in America? How do we have a system of mutual benefits where people succeed by helping others improve their lives? So I don't like that at all.

What we need to work on is how to increase productivity. And then everybody will be better off.
