I don't believe in a plumb line. I believe in the exchange of ideas.

A lot of what is done by the climate lobby is anti-science. But there is some science behind it. Like, there are greenhouse gases, and they do contribute to warming. But if you look at the last, say, 160 years, the first 80 of that period, they went up about four-tenths of a degree. And now, the second 80 that CO2 has increased by, what, 30 percent or something, it's gone up five-tenths of a degree. And there's been in the last 30 or 40 years, there's been no real increase in storms or bad weather.

Just Donald Trump's tenor and insulting of people is just beyond the pale.

If you never failed, then you're probably not doing very much.

The old idea that some genius pulls all of this stuff out of the air is ridiculous. As Ridley pointed out, the only way Edison could invent the lightbulb is because all the elements had been developed before. That's obvious it wasn't just his genius - 20 others developed it at the same time. And that's true for almost every invention and discovery.

If what you preach and what you do are inconsistent, your children will spot hypocrisy faster than anybody and do the opposite.

No centralized government, no matter how big, how smart or how powerful, can effectively and efficiently control much of society in a beneficial way. On the contrary, big governments are inherently inefficient and harmful.
