The meaning in life is not out there but inbetween our ears. In many ways this makes us the lords of creation.
Stephen HawkingOne can see from space how the human race has changed the Earth. Nearly all of the available land has been cleared of forest and is now used for agriculture or urban development. The polar icecaps are shrinking and the desert areas are increasing. At night, the Earth is no longer dark, but large areas are lit up. All of this is evidence that human exploitation of the planet is reaching a critical limit. But human demands and expectations are ever-increasing. We cannot continue to pollute the atmosphere, poison the ocean and exhaust the land. There isn't any more available.
Stephen HawkingWe are all different. There is no such thing as a standard or run-of-the-mill human being, but we share the same human spirit.
Stephen HawkingAlthough September 11 was horrible, it didn't threaten the survival of the human race, like nuclear weapons do.
