It’s generally unremarkable in the US if someone does not believe in evolution, the cornerstone of modern science. Only 39 percent of Americans answer yes to the question, “Do you believe that human beings as we know them developed from earlier species of animals?”
Given the ubiquity of the Biblical viewpoint in the US, it’s therefore heartening that Sam Brownback felt the need to expand on his views in today’s New York Times. Perhaps he feels that the remaining 61% of the electorate may require some reassurance that he’s a reasonable man and that he won’t be turning the republic into a theocracy. The problem is that Brownback’s Op Ed piece makes no kind of sense at all and does anything but reassure.
In the May 3 televised debate of Republican presidential hopefuls, Sen. John McCain was asked if he believed in evolution. McCain said “Yes,” and then added, “I believe in evolution. But I also believe, when I hike the Grand Canyon and see it at sunset, that the hand of God is there also.” The candidates were then asked en masse to indicate who did not believe in evolution. Three hands went up: former Arkansas governor Mike Huckabee, Kansas Senator Sam Brownback and Colorado congressman Tom Tancredo. The debate then moved on with no follow-up, which is perhaps excusable given that there were ten candidates and only 90 minutes.
Brownback’s thesis is as follows: “The heart of the issue is that we cannot drive a wedge between faith and reason. I believe wholeheartedly that there cannot be any contradiction between the two.”
So that’s an interesting start. There can be no contradiction between faith and reason. So if I have faith that Senator Brownback is actually an Alpha Centaurian hell-bent on the conquest of Earth, this cannot be contradictory to reason because it’s my faith, and faith and reason cannot be contradictory. Similarly, if I believe that the word was created from the fragments of an egg laid by a duck on the knee of Ilmatar, goddess of the air, or that the world was created last Thursday and everything that supposedly predates that day is an illusion devised by the flying spaghetti monster, then that too cannot be in contradiction to reason.
But what the Senator no doubt means is that reason and his faith — that is the Bible — cannot be contradictory.
Brownback explains, “[Science and Faith] deal with very different questions, but they do not contradict each other because the spiritual order and the material order were created by the same God.”
This is what’s known in logic as “begging the question,” in which the proposition to be proved is assumed implicitly or explicitly in one of the premises. In other words this is circular reasoning. Science (the study of the material order) cannot contradict Brownback’s faith that God created the material order because God created the material order.
Despite this illogic, he does believe that “people of faith should be rational.” That’s a noble wish, and one with which I heartily concur, except that he’s already said in effect that he’s not prepared to accept any rational evidence that happens to contradict his faith in the Bible and its supposed literal truth.
Brownback goes on to make nonsense of his statement that people of faith should be rational by making another irrational statement:
“If belief in evolution means simply assenting to microevolution, small changes over time within a species, I am happy to say, as I have in the past, that I believe it to be true. If, on the other hand, it means assenting to an exclusively materialistic, deterministic vision of the world that holds no place for a guiding intelligence, then I reject it.”
The irrationality here is that Brownback poses a false dichotomy for himself (and us) to choose between. We can have small changes over time within a species OR we can have an exclusively materialistic, deterministic vision of the world. There can be Biblical literalism with its fixed species, or we can have the Darwinian evolution of species along with cold, hard, atheistic materialism. There are of course many other possible options to choose from, including a God who creates the universe eons ago and who then watches his creation evolve, and nontheistic and nonmaterialistic faiths such as Buddhism, which have no problem accepting the evolution of species.
Apparently Senator Brownback is not able to use his rationality to examine his own thinking.
The Senator is generous in exposing the hollowness of his own embrace of rationality by rejecting evidence, no matter how overwhelming, that contradicts his beliefs: “Ultimately, on the question of the origins of the universe, I am happy to let the facts speak for themselves. There are aspects of evolutionary biology that reveal a great deal about the nature of the world, like the small changes that take place within a species.”
He is happy to let the facts speak for themselves, but only if they support the biblically acceptable notion of gradual changes within a species. However the evidence that species are no immutable and that new species can come into being is, to put it mildly, overwhelming. So is the evidence that the Earth and the universe and immeasurably older than the 6,000 years that purely Biblical evidence would support.
Unsurprisingly, Brownback reveals that fundamentally he does not “get” science: “It does not strike me as anti-science or anti-reason to question the philosophical presuppositions behind theories offered by scientists who, in excluding the possibility of design or purpose, venture far beyond their realm of empirical science.”
The purpose of science is to form hypotheses that explain observations, and then to find evidence that may support or undermine those hypotheses. Those hypotheses that gather overwhelming support in the form of repeated observations become “theories.” This includes theories such as gravity, relativity, and evolution. If there were any evidence that supported the contention that life was designed by an intelligence, then that would be examined and debated vigorously by scientists. However the evidence that life was not designed is, again, overwhelming. We simply have to look at the structure of the human eye, which has wiring on top of the receptors, or the existence of vestigial limbs in snakes, or the existence of junk DNA, to see that living beings have — in a strictly metaphorical way — cobbled themselves together.
Brownback continues to expose his fundamental opposition to rationality right up to the end of his article:
“While no stone should be left unturned in seeking to discover the nature of man’s origins, we can say with conviction that we know with certainty at least part of the outcome. Man was not an accident and reflects an image and likeness unique in the created order.”
Apparently “we know with certainty” that “man was not an accident.” There is of course no evidence whatsoever that man was not an accident!
“Those aspects of evolutionary theory compatible with this truth are a welcome addition to human knowledge. Aspects of these theories that undermine this truth, however, should be firmly rejected as an atheistic theology posing as science.”
Again, truth is welcomed when it agrees with Brownback’s Bible. Any evidence that contradicts the Bible should be met with ad hominen reductionism. If I demonstrate through fossil evidence and DNA studies that human beings have evolved from ape-link ancestors then I am apparently merely “posing” as a scientist, and my motivation is to promote — in Brownback’s delightfully oxymoronic term — an “atheistic theology.”
A number of things are clear from Brownback’s piece. First, he is afraid enough of public ridicule to have to explain himself. Second, he is almost certainly not capable of thinking rationally, because he has made an a priori assumption that what the Bible says trumps any evidence that may come his way. Third, he lacks self-awareness because he’s unwilling or unable to examine his own beliefs and thinking in a critical way. Fourth, he will not hold back from demonizing anyone who does present evidence that contradicts his Biblical beliefs. Lastly, he is, like many fundamentalist Christians, an inveterate perpetrator of falsehoods, prepared to present false dichotomies, to beg questions, and to claim as certain that which is open to question.
In short Senator Brownback is an irrational man, lacking in the qualities of intellectual honesty and clarity of thought necessary for the office of President. I’ll raise my hand to that.
