Although personally, I think cyberspace means the end of our species.

Theories are just fantasies. And they change.

It's better to die laughing than to live each moment in fear.

We are all assumed, these days, to reside at one extreme of the opinion spectrum, or another. We are pro-abortion or anti-abortion. We are free traders or protectionists. We are pro-private sector or pro-government. We are feminists or chauvinists. But in the real world, few of us hold these extreme views. There is instead a spectrum of opinion.

You think you can destroy the planet? What intoxicating vanity. . . . . We've been residents here for the blink of an eye. If we're gone tomorrow, the earth will not miss us.

The work of science has nothing whatever to do with consensus. Consensus is the business of politics. Science, on the contrary, requires only one investigator who happens to be right, which means that he or she has results that are verifiable by reference to the real world. In science consensus is irrelevant. What is relevant is reproducible results. The greatest scientists in history are great precisely because they broke with the consensus.

Human intelligence was more trouble than it was worth. It was more destructive than creative, more confusing than revealing, more discouraging than satisfying, more spiteful than charitable.
