What Should Be Called Science?
What is, or should be, allowed to earn the moniker scientific? This is not only the fundamental question in the dispute between ID and evolution but it is one of the fundamental questions in a philosophy of science that would be used to decide the question.
Where do we find the division between science that lies outside of physical studies and set this against matters of theology and philosophy? There are, after all, sciences that do not comply with either physicalism (the constraint that only the physical is studied) or methodological naturalism (the constraint that only the physical can be studied). These would include topics like tachyon theory and string theory, topic that are by consensus "science" but at the same time
From what I can tell, it is a minority that understand the greater structure of what is called evolution. The common-knowledge aproach says that evolution is nothing more than the theory of common descent. To come to this conclusion is just as superfluous as saying that all religions are the same because the all talk about a deity. In the case of religion we know that there is a great deal of difference, and these are exclusive differences, between pantheism, polytheism, monotheism, and fatalism. That there is a common characteristic between them is quite immaterial to their overall divergent theory structures. All theologies are theory structures and all scientific theorys are also structures, systematized to draw particular conclusions. The various evolutionary theory structures have their common features yet vary significantly. This variation is adequate to describe each of them as exclusive models. There is not one model, one theory of evolution. In today's world there are three, and perhaps four, that account for the subject.
But if no more than one of them is true, doesn't that mean that creaiton is automatically allowed into the discussion? On the PhiSci (Philosophy of Science) side of the discussion, I don't think that when good science goes beyond these two constraints that it necessarily allows theology in general or creation in particular. But what does happen, and this seems patently obvious, is that any sound criticism of an evolutionary model (a designation that I did not see in Coyne's book) leaves the theory structure lacking the certainty that Coyne, in his recent book Why Evolution Is True, gets all excited about. His certainty is unwarranted. That does, at least, leave room for other models that can rightly apply the scientific findings and answer other questions.
One of the core construction problems involves the demand for naturalism, either methodological or metaphysical (because methodological demands metaphysical), within the theory structure itself. The difficulty here is the naturalism -- it is a presumption. It is not part of the evidence and it is not part of the process. Presuppositions must be kept in their place. When a scientist demans naturalism in either form he automatically exist any experiment or test and is immediately engaged in philosophy. Doing so necessarily begs the question and automatically invalidates the test. (That's not to say that the test might be valid, but that it cannot be valid if it includes the presuppostion.)
A presupposition differs signification from an assumption. Presuppositions can be thought of as driving ideas while assumptions actually guide the mechanics of the process. In the case of the evolutionary model the general assumption is naturalism and the leading assumption is common descent. An evolutionary model can be executed without naturalism but few have attempted such an endeavor.
There are those of us in the OEC community who see the age of the earth, and also the whole universe, as indeterminable. Some, as you may have read, like to set dates of 50KY or 125KY, but those almost certainly defy the fossil record. What is necessary for an alternative model is one that is consistent with scientific findings and at the same time avoids the unnecessary contradictions and confusions of the current evolutionary models.
Evolutionary Models? Is there more than one evolutionary model? There are at least three. There is first the classic Darwinist position that can be identified by uniformitarian graudalism. The second is a variation as promoted by Dawkins, an accelerated gradualism. Then there is the Punctuated Equilibrium of Gould, et. al. Each of these finds certain supporting evidence in both the lab and/or the fossil record. Yet the orthodoxy of each is intended to disprove its predecessor and create a new solution to questions that pop up, and not just from creationists. There is also a fourth, a synthetic system that attempts to blend the three as needed, depending on the evidence.
Some will say that these are simply mechanisms, that all somehow attempt to explain the assumption of common descent. The problem is that each of these mechanism defines a whole new solution, and that is a new model. In addition, these mechanisms are exclusive in their claims. They may bear in common the assumption of common descent, but differ significantly in these other respects. They are all evolution the same way that protestants and Roman Catholics, and Orthodox are all Christian. Yet they are all exclusive in the same way that sola gracie and sola fide separate protestants to an exclusive position, and the authority of the Roman bishop is exclusive from the Orthodox bishop. The three, in each respective case, are exclusive systems with a common assumption. None are the same even though they share common traits. Though most of Christedom rejects the principle, the evolutionary community seems to enjoy its own eccumenism, despite the exclusive differences.
Now we come to a crux, a crisis, a place for a decision. Actually a couple. How can exclusive positions be reconciled? In simple terms, they cannot. This is a reasonable challenge for the naturalist evolutionists. How can evolution demand naturalism without begging the question? It cannot, at least not and be considered valid as a theory structure. But evolutionists do, and modifying their theory accordingly also seems to be a reasonable challenge.
Objection 1: When I read Darwin and many others there is no mention of naturalism or of a Godless universe. How is that latter challenge valid?
Answer: Part of today's popular dialogue demands that evolution always be framed and discussed within the context of naturalism. There is a distinct and clear refusal to employ only physicalism. Jason Rosenhouse quotes Jerry Coyne:
I am a methodological naturalist, but I don't think that all supernatural claims defy scientific analysis. Moreover, I don't see that the methodological/philosophical distinction has a lot to do with the dissonance between faith and science. The real dissonance, as I have repeatedly emphasized, is between the scientific acceptance of only those claims adjudicated by empirical investigation, and the religious acceptance of “truth” claims that are discovered by revelation (or instruction by one's parents) and are unfalsifiable. These are two fundamentally different and incompatible ways of ascertaining “truth.” In fact, I don't see that religion has any way at all of ascertaining “truth,” since its claims cannot be falsified.
Objection 2: This looks like an attempt to simply be scientific and avoid mixing religion with science.
Answer: Coyne confused issues of theory structure. The call to reject some questions because they cannot be "falsified" is a specious objection. Falsification is a matter of methodology and structure which religious matters do not fit into. Of equal importance is that falsification does not apply to evolutionary theory for the same reason. Evolution is a structure, not a positivist RV formula structure.
Evolution cannot be falsified. We cannot prove it wrong like 1+1=3. The best that we can do is expose the fallacies of the theory structure and challenge, and then remove, the current level of certainty that it does not deserve.
