Stifling Intellectual Inquiry

Richard Neuhaus has an excellent little essay on the Intelligent Design/ Darwinism debate in the April issue of First Things. Here are a couple of paragraphs of an article that should be read in its entirety:

That evolution is a theory is a fact, unless somebody has changed the definition of theory without notifying the makers of dictionaries. The "search for knowledge" and "the pursuit of science," one might suggest, will suffer grievously if we no longer respect the distinction between theory and fact.

To argue that skepticism about the theory of evolution is inadmissible if it is motivated by religion is simply a form of antireligious bigotry. It is a fact that many devout Christians, many of whom are engaged in the relevant sciences, subscribe to the theory of evolution. It is also a fact that some scientists who reject religion also reject evolution, or think the theory highly dubious. That is the way it is with theories.

To simply equate evolutionary theory with science is a form of dogmatism that has no place in the pursuit of truth. The problems with that approach are multiplied by the fact that there are such starkly conflicting versions of what is meant by evolution. The resistance to the theory is almost inevitable when it is propounded, as it often is, in an atheistic and materialistic form.

Atheism and materialism are not science but ideologies that most people of all times and places, not just "red state" Americans, deem to be false. Proponents of "intelligent design" and other approaches, who are frequently well-certified scientists, contend that their theories possess greater explanatory power.

Some school boards have very modestly suggested that students should know that evolution is not the only theory about the origin and development of life. What they want students to know is an indisputable fact. There are other theories supported by very reputable scientists, including theories of evolution other than the established version to which students are now bullied into giving their assent.

On any question, the rational and scientific course is to take into account all pertinent evidence and explanatory proposals. We can know that the quasi-religious establishment of a narrow evolutionary theory as dogma is in deep trouble when its defenders demand that alternative ideas must not be discussed or even mentioned in the classroom. Students, school boards, and thoughtful citizens are in fully justified rebellion against this attempted stifling of intellectual inquiry.

On the matter of taking into account all pertinent evidence and explanatory proposals one often hears the objection that if we are going to be fair in introducing alternative explanations into the classroom we will have to give time to a menagerie of ideas from pantheistic to animistic creation stories and everything in between. This is, of course, a transparently disingenuous attempt to justify continuing the monopoly enjoyed by the materialistic explanation.

The fact is there are not an indefinite number of alternative explanations which would have to be accommodated. There are precisely two genuine options in this debate. Life either arose by purely mindless, mechanistic processes, or it's appearance involved some degree of intelligent input. These two disjuncts exhaust all the possibilities. Nothing else need be discussed.

Nor is it correct to assert that one of these alternatives is a scientific hypothesis and the other is religious. They are both metaphysical explanations. Neither of them is ultimately provable or disprovable by any empirical test. If one is to be excluded they should both be excluded, if one is to be presented in public school classrooms they should both be presented in public school classrooms. There is no reason why the materialist theory should be privileged over it's competitor.

This is all that most people who are trying to get Intelligent Design acknowledged in high school biology classes are asking. They wish to see students genuinely challenged to think through the two contrasting theories and be allowed to decide for themselves which one best accounts for the evidence. Do living things show indications of having been intentionally designed or do they instead appear to have resulted from mindless, purposeless physical laws plus serendipity?

The guardians of the entrenched materialist orthodoxy know very well which possibility will have the greatest intellectual and philosophical allure for students, and that's precisely why they are so determined to prevent the comparison.
