"As the twentieth century drew to a close, the connection between hard scientific fact and public policy became increasingly elastic. In part this was possible because of the complacency of the scientific profession; in part because of the lack of good science education among the public; in part, because of the rise of specialized advocacy groups which have been enormously effective in getting publicity and shaping policy; and in great part because of the decline of the media as an independent assessor of fact."

“The romantic view of the natural world as a blissful Eden is only held by people who have no actual experience of nature. People who live in nature are not romantic about it at all. They may hold spiritual beliefs about the world around them, they may have a sense of the unity of nature or the aliveness of all things, but they still kill the animals and uproot the plants in order to eat, to live. If they don't, they will die.”

“Once you abandon strict adherence to what science tells us, once you start arranging the truth in a press conference, then anything is possible. In one context, maybe you will get some mobilization against nuclear war. But in another context, you get Lysenkoism. In another, you get Nazi euthanasia. The danger is always there, if you subvert science to political ends.”

“I think that you cannot eliminate religion from the psyche of mankind. If you suppress it in one form, it merely emerges in another form. Even if you don't believe in God, you still have to believe in something that gives meaning to your life, and shapes your sense of the world. Such a belief is religious.”

“Every one of us has a sense of the world, and we all know that this sense is in part given to us by what other people and society tell us; in part generated by our emotional state, which we project outward; and in part by our genuine perceptions of reality. In short, our struggle to determine what is true is the struggle to decide which of our perceptions is genuine, and which are false because they are handed down, or sold to us, or generated by our own hopes and fears.”

“Science is the most exciting and sustained enterprise of discovery in the history of our species. It is the great adventure of our time. We live today in an era of discovery that far outshadows the discoveries of the New World five hundred years ago.”

“Things do not turn out the way you think they will.”
