It is often said by opponents of Intelligent Design that this is not a scientific question, and therefore cannot be a valid part of scientific enquiry. For example, in his column Intelligent Design not science by Richard Olmstead, we are told:
"Science classes should teach alternate scientific theories wherever competing theories collide. However, for a theory to be "scientific," it must provide the basis for testable hypotheses. Scientists and philosophers agree -- if a theory is not amenable to testing, it doesn't belong in a science classroom.
Intelligent design offers no testable hypotheses and, instead, offers only an explanation for observations of complex structures and phenomena in biology that must be taken on faith..."
Now, I understand the need to be able to test and either verify or falsify an hypothesis, but what I do not understand is why Olmstead, and other opponents of ID make the claim that ID is not a testable theory. Consider the following examples:
Imagine a doctor performing an autopsy in which the good doctor has decided, from the outset, that the cause of death must be entirely natural, or, at most, accidental. Any possibility of the subject having been murdered is ruled out a priori. I do not think that most of us would find this position to be, at best, odd, and more probably would consider it to be incompetent. If there is evidence that a person was murdered, then we must not expect the coroner to declare this to be impossible but we already "know" that the cause of death must be either by natural causes, or an accident.
Now consider an archeologist on a dig who finds some rocks that could be either tools or merely natural occuring rocks. If this archeologist told us before the dig that it is not possible for anything he finds to be shown to have been created by a tool making mind, then we should not be surprised that he would declare his knife shaped stone to be a mere fluke of nature.
Our third example involves an arson investigator brought in to investigate a fire. Before she begins she tells everyone that she already knows that all fires begin by accident or as acts of nature, so there is no chance that a human being could have set this fire. One need only imagine the reaction.
Each of the above examples involves a scientist engaging in his or her work. Had any of them ruled out the possibility that their investigation would uncover evidence of being the product of an intelligent mind would be drummed out of the business, and rightly so. This leaves me to wonder if the opponents of Intelligent Design actually understand the purposes of science.
