First Things: The End of Intelligent Design?
It is time to take stock: What has the intelligent design movement achieved? As science, nothing. The goal of science is to increase our understanding of the natural world, and there is not a single phenomenon that we understand better today or are likely to understand better in the future through the efforts of ID theorists. If we are to look for ID achievements, then, it must be in the realm of natural theology. And there, I think, the movement must be judged not only a failure, but a debacle.
Very few religious skeptics have been made more open to religious belief because of ID arguments. These arguments not only have failed to persuade, they have done positive harm by convincing many people that the concept of an intelligent designer is bound up with a rejection of mainstream science.
The ID claim is that certain biological phenomena lie outside the ordinary course of nature. Aside from the fact that such a claim is, in practice, impossible to substantiate, it has the effect of pitting natural theology against science by asserting an incompetence of science. To be sure, there are questions that natural science is not competent to address, and too many scientists have lost all sense of the limitations of their disciplines, not to mention their own limitations. But the ID arguments effectively declare natural science incompetent even in what most would regard as its own proper sphere. Nothing could be better calculated to provoke the antagonism of the scientific community. This throwing down of the gauntlet to science explains not a little of the fervor of the scientific backlash against ID. ...
