"The science says you must do what you want to do anyway", seems to be what the Bush administration wants to hear from the scientific community. Only that's not what happens.
Like every other field of human endeavour, science is a fallible, but it does set up a methodology to try and eliminate error and refine truth: the scientific method.
What science does not, and cannot offer, is complete certainty.
So when the world's only hyper power falls into the grip of a group of people who regard the Bible as an alternative to science, you know we have returned to the sort of bigotry which was so widespread before the Enlightenment, and which never fully left us. (Northern Ireland offers a home-grown paradigm.)
Were it happening in any other country, we could ignore it. But it's not. American policy, as we know, has world-wide ramifications. Climate change being a major example.
Chris Mooney offers a history of, and an explanation for, the rise of the religious Right in the USA, and describes its link to corporations, and their resentment of government regulation.
Within this coalition there is both a resentment of education, and a resentment of the findings of scientific research which threaten both the core ideology and policies springing from them.
Whilst the author sounds a valid warning against misuses of science coming from the Left, he believes it to be a much larger problem from the Right.
The AIDS epidemic was an early victim. Ronald Reagan's domestic policy adviser did not want children educated in the use of condoms, so AIDS was not mentioned during Reagan's first term.
The tobacco barons did not like the results of research on passive smoking, so they funded their own "research" group which challenged the findings of the Environmental Protection Agency, and worked to undermine its credibility.
Global warming is not man-made. Exxon funded policy groups to say so. George Bush likes to talk about the "incomplete state of scientific knowledge" on this subject. (In this context The Daily Telegraph frequently publishes "findings" purporting to show that climate change is a fiction.)
Evolution contradicts Genesis. Intelligent design is built-up as an alternative that sounds more scientific than Creationism, but is merely another way of saying God created Man. Ergo, evolution is only a theory, and - thank God! - our ancestors were not apes.
(Creationism tried to stick to the creation-in-4004-BC-theory, which even the American Right now realise does not stand up!)
Abortion is sinful, but it also causes breast cancer, and triggers mental illness. Ergo: abortion is also bad for you, "science" says so.
I hope you get the flavour.
This book is carefully balanced, and it offers detailed explanatory background which is especially welcome on the difficult subject of stem cell research.
Above all it's a good read.
