A truly free society is based on a vision of respect for people and what they value.

I love to try to understand first principles and be guided by that. But then, enrich them, because they won't last forever, just like everybody thought Newton had all the answers. And you probably read that, in the last of the 19th century, Harvard and others were discouraging people from going into physics because we have all the answers. And right after that, of course - we have - all this stuff is thrown out the window. And now we have whole new answers.

If somebody is doing more and more to make other people's lives better, have them make all they can, if that's what drives them, because that's what we want.

If we are going to have a Fed, it should not fall into the tyranny of experts with the a fatal conceit that a few wise people can determine interest rates. Interest rates should be driven by the market, and people's time preference, and we see these boom-bust cycles.

If there is wrong, you don't say we have to get rid of it gradually. If injustice exists, you need to eliminate it immediately.

That's the first rule for anybody who controls - do no harm.

The role of business is to provide products and services that make peoples lives better - while using fewer resources - and to act lawfully and with integrity.
