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

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.

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.

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.

I suspect any worries about genetic engineering may be unnecessary. Genetic mutations have always happened naturally, anyway.

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.

I'm wishing this was something else I was writing, but, Pops, we've got to let you know we love you and know you'll always be with us.

Right" he said "Let's get one thing clear. I am not here to teach you law-I am here to teach you loopholes.

The truth is that I'm constitutionally incapable of doing an ordinary job.

In the age of revolution you have to be able to imagine revolutionary alternatives to the status quo. If you can't, you'll be relegated to the swollen ranks of keyboard-pounding automatons.

I often quote an African proverb that says: "The world is not ours, the earth is not ours, It's a treasure we hold in trust for future generations." And I often hope we will be worthy of that trust.

You'd think one day we'd learn. You don't get anything unless you fight for it, united and with visible numbers. If ACT UP taught us anything, it taught us that.

Tell me what time you spend alone with God... and I'll tell you how spiritual you are.

Anger is temporary madness.

Some things it don't pay to be curious about.

It is strange that the tactile sense, which is so infinitely less precious to men than sight, becomes at critical moments our main, if not only, handle to reality.
