Real life isn't a series of interconnected events occurring one after another - like beads strung on a necklace. Life is actually a series of encounters in which one event may change those that follow in a wholly unpredictable, even devastating way.

In order not to be misunderstood, I want it perfectly clear that I believe it is incumbent on us to conduct our lives in a way that takes into account all the consequences of our actions, including the consequences to other people, and the consequences to the environment.

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.

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.

We need to get environmentalism out of the sphere of religion. We need to stop the mythic fantasies, and we need to stop the doomsday predictions. We need to start doing hard science instead.

That's human nature. Nobody does anything until it's too late.

Sometimes I think man needs to feel a special position within nature, and this leads him to believe that he is either specially hated by other animals or specially cherished. Instead of the truth, which is that he's just another animal on the plain. A smart one, but just another animal.
