Our future is like that of the passengers on a small pleasure boat sailing quietly above the Niagara Falls, not knowing that the engines are about to fail.

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.

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.

Every day you play with the light of the universe.

The strictest justice is sometimes the greatest injustice.

People need patience. It takes time to build a brand.

I say quotations are literary. They are good only when dealing with ideas, not with experience. Experience should be pure, unique.

People are tired of just watching their TV set passively. They are playing interactive games today. They are on the Internet interacting. They want to be part of their TV set.

Always sailing, sailing, sailing...never quite reaching.

It's the best thing in the world, the most challenging thing in the world, being a parent, and one of the first lessons I learned was to ask for help.

We don't do that kind of thing. We don't create registries based on religion.

As for the United States' future in Afghanistan, it will be fire and hell and total defeat, God willing, as it was for their predecessors - the Soviets and, before them, the British.

I don't believe in making pencil sketches and then painting landscape in your studio. You must be right under the sky.
