Famed Scientist Richard Dawkins Destroys Rick Perry on Evolution

AlterNet.org

We all know Texas Governor and GOP Presidential Candidate Rick Perry is full of it with his anti-science agenda, and we've read about his close ties to a cadre of religious extremists who have anointed him for privileging religion over scientific evidence (his "pray for rain" moment being a prime example).

Still, a smackdown from none other than Richard Dawkins on the subject of those outmoded, dangerous beliefs has a particularly satisfying highbrow but low-blow quality to it. Dawkins, an evolutionary bioligist and outspoken atheist, delivered such a smackdown to Perry in the course of a Q and A in the Washington Post's On Faith column.

Dawkins said that while a candidate's views on evolution are not paramount, they're indicative of his or her ability to understand science and his or her general levels of educational literacy.

He also had harsh words for the valuation of ignorance among the Republican electorate.

Here are some choice excerpts:

There is nothing unusual about Governor Rick Perry. Uneducated fools can be found in every country and every period of history, and they are not unknown in high office. What is unusual about today’s Republican party (I disavow the ridiculous ‘GOP’ nickname, because the party of Lincoln and Theodore Roosevelt has lately forfeited all claim to be considered ‘grand’) is this: In any other party and in any other country, an individual may occasionally rise to the top in spite of being an uneducated ignoramus. In today’s Republican Party ‘in spite of’ is not the phrase we need. Ignorance and lack of education are positive qualifications, bordering on obligatory. Intellect, knowledge and linguistic mastery are mistrusted by Republican voters, who, when choosing a president, would apparently prefer someone like themselves over someone actually qualified for the job.

***

A politician’s attitude to evolution is perhaps not directly important in itself. It can have unfortunate consequences on education and science policy but, compared to Perry’s and the Tea Party’s pronouncements on other topics such as economics, taxation, history and sexual politics, their ignorance of evolutionary science might be overlooked. Except that a politician’s attitude to evolution, however peripheral it might seem, is a surprisingly apposite litmus test of more general inadequacy. This is because unlike, say, string theory where scientific opinion is genuinely divided, there is about the fact of evolution no doubt at all. Evolution is a fact, as securely established as any in science, and he who denies it betrays woeful ignorance and lack of education, which likely extends to other fields as well. Evolution is not some recondite backwater of science, ignorance of which would be pardonable. It is the stunningly simple but elegant explanation of our very existence and the existence of every living creature on the planet. Thanks to Darwin, we now understand why we are here and why we are the way we are. You cannot be ignorant of evolution and be a cultivated and adequate citizen of today.

I'd love to see Dawkins debate Perry on live TV, wouldn't you?

Attention Governor Perry: Evolution is a fact

Q. Texas governor and GOP candidate Rick Perry, at a campaign event this week, told a boy that evolution is ”just a theory” with “gaps” and that in Texas they teach “both creationism and evolution.” Perry later added “God is how we got here.” According to a 2009 Gallup study , only 38 percent of Americans say they believe in evolution. If a majority of Americans are skeptical or unsure about evolution, should schools teach it as a mere “theory”? Why is evolution so threatening to religion?

A. There is nothing unusual about Governor Rick Perry. Uneducated fools can be found in every country and every period of history, and they are not unknown in high office. What is unusual about today’s Republican party (I disavow the ridiculous ‘GOP’ nickname, because the party of Lincoln and Theodore Roosevelt has lately forfeited all claim to be considered ‘grand’) is this: In any other party and in any other country, an individual may occasionally rise to the top in spite of being an uneducated ignoramus. In today’s Republican Party ‘in spite of’ is not the phrase we need. Ignorance and lack of education are positive qualifications, bordering on obligatory. Intellect, knowledge and linguistic mastery are mistrusted by Republican voters, who, when choosing a president, would apparently prefer someone like themselves over someone actually qualified for the job.

Any other organization -- a big corporation, say, or a university, or a learned society - -when seeking a new leader, will go to immense trouble over the choice. The CVs of candidates and their portfolios of relevant experience are meticulously scrutinized, their publications are read by a learned committee, references are taken up and scrupulously discussed, the candidates are subjected to rigorous interviews and vetting procedures. Mistakes are still made, but not through lack of serious effort.

The population of the United States is more than 300 million and it includes some of the best and brightest that the human species has to offer, probably more so than any other country in the world. There is surely something wrong with a system for choosing a leader when, given a pool of such talent and a process that occupies more than a year and consumes billions of dollars, what rises to the top of the heap is George W Bush. Or when the likes of Rick Perry or Michele Bachmann or Sarah Palin can be mentioned as even remote possibilities.

A politician’s attitude to evolution is perhaps not directly important in itself. It can have unfortunate consequences on education and science policy but, compared to Perry’s and the Tea Party’s pronouncements on other topics such as economics, taxation, history and sexual politics, their ignorance of evolutionary science might be overlooked. Except that a politician’s attitude to evolution, however peripheral it might seem, is a surprisingly apposite litmus test of more general inadequacy. This is because unlike, say, string theory where scientific opinion is genuinely divided, there is about the fact of evolution no doubt at all. Evolution is a fact, as securely established as any in science, and he who denies it betrays woeful ignorance and lack of education, which likely extends to other fields as well. Evolution is not some recondite backwater of science, ignorance of which would be pardonable. It is the stunningly simple but elegant explanation of our very existence and the existence of every living creature on the planet. Thanks to Darwin, we now understand why we are here and why we are the way we are. You cannot be ignorant of evolution and be a cultivated and adequate citizen of today.

Darwin’s idea is arguably the most powerful ever to occur to a human mind. The power of a scientific theory may be measured as a ratio: the number of facts that it explains divided by the number of assumptions it needs to postulate in order to do the explaining. A theory that assumes most of what it is trying to explain is a bad theory. That is why the creationist or ‘intelligent design’ theory is such a rotten theory.

What any theory of life needs to explain is functional complexity. Complexity can be measured as statistical improbability, and living things are statistically improbable in a very particular direction: the direction of functional efficiency. The body of a bird is not just a prodigiously complicated machine, with its trillions of cells - each one in itself a marvel of miniaturized complexity - all conspiring together to make muscle or bone, kidney or brain. Its interlocking parts also conspire to make it good for something - in the case of most birds, good for flying. An aero-engineer is struck dumb with admiration for the bird as flying machine: its feathered flight-surfaces and ailerons sensitively adjusted in real time by the on-board computer which is the brain; the breast muscles, which are the engines, the ligaments, tendons and lightweight bony struts all exactly suited to the task. And the whole machine is immensely improbable in the sense that, if you randomly shook up the parts over and over again, never in a million years would they fall into the right shape to fly like a swallow, soar like a vulture, or ride the oceanic up-draughts like a wandering albatross. Any theory of life has to explain how the laws of physics can give rise to a complex flying machine like a bird or a bat or a pterosaur, a complex swimming machine like a tarpon or a dolphin, a complex burrowing machine like a mole, a complex climbing machine like a monkey, or a complex thinking machine like a person.

Darwin explained all of this with one brilliantly simple idea - natural selection, driving gradual evolution over immensities of geological time. His is a good theory because of the huge ratio of what it explains (all the complexity of life) divided by what it needs to assume (simply the nonrandom survival of hereditary information through many generations). The rival theory to explain the functional complexity of life - creationism - is about as bad a theory as has ever been proposed. What it postulates (an intelligent designer) is even more complex, even more statistically improbable than what it explains. In fact it is such a bad theory it doesn’t deserve to be called a theory at all, and it certainly doesn’t deserve to be taught alongside evolution in science classes.

The simplicity of Darwin’s idea, then, is a virtue for three reasons. First, and most important, it is the signature of its immense power as a theory, when compared with the mass of disparate facts that it explains - everything about life including our own existence. Second, it makes it easy for children to understand (in addition to the obvious virtue of being true!), which means that it could be taught in the early years of school. And finally, it makes it extremely beautiful, one of the most beautiful ideas anyone ever had as well as arguably the most powerful. To die in ignorance of its elegance, and power to explain our own existence, is a tragic loss, comparable to dying without ever having experienced great music, great literature, or a beautiful sunset.

There are many reasons to vote against Rick Perry. His fatuous stance on the teaching of evolution in schools is perhaps not the first reason that springs to mind. But maybe it is the most telling litmus test of the other reasons, and it seems to apply not just to him but, lamentably, to all the likely contenders for the Republican nomination. The ‘evolution question’ deserves a prominent place in the list of questions put to candidates in interviews and public debates during the course of the coming election.

Richard Dawkins wrote this response to Governor Perry for On Faith, the Washington Post’s forum for news and opinion on religion and politics.
