The problem is we don't know what the climate is doing. We thought we knew 20 years ago. That led to some alarmist books - mine included - because it looked clear-cut, but it hasn't happened.

I have heard that the Saudi Arabians are paying Greenpeace to campaign against Nuclear Power. It wouldn't surprise me at all.

NASA will send up a big sun shade that will be in orbit between the earth and sun and deflect 2 or 3 percent of the sunshine back into space. It would be cheaper than the international space station.

Evolution is a tightly coupled dance, with life and the material environment as partners. From the dance emerges the entity Gaia.

There aren't just bad people that commit genocide; we are all capable of it. It's our evolutionary history.

Let's make hay while it lasts.

Perhaps the single most important thing that we can do to undo the harm we have done is to fix firmly in our minds the thought: the earth is alive.

Nature favors those organisms which leave the environment in better shape for their progeny to survive.

The oil companies regard nuclear power as their rival, who will reduce their profits, so they put out a lot of disinformation about nuclear power.

If you start any large theory, such as quantum mechanics, plate tectonics, evolution, it takes about 40 years for mainstream science to come around. Gaia has been going for only 30 years or so.

Carry your heart through this world like a life-giving sun

Thanksgiving began in 1621 when Native Americans sat down with a bunch of undocumented pilgrims. They had dinner and the pilgrims never left.

André Weil always looked like that, not only when he talked about the devil.

God is not asking us to not have anything or even to give away every single thing that we have. He is asking us to share with people who have less than us, which we do all the time.

In summoning even the wisest of physicians to our aid, it is probably that he is relying upon a scientific "truth", the error of which will become obvious in just a few years' time.

Fredo, you're my older brother and I love you. But don't ever take sides against the Family again. Ever.

I'm more relaxed about life now that I'm older. I like it-despite the wrinkles. It's what I feel inside that's precious.

The greatest event for the world is the arrival of a new and wise person.
