Science and Its Limits, 2000
"The scientific attitude has usually been characterised as a commitment to following the evidence wherever it leads. That does not look like promising ammunition for someone pushing an official policy of refusing to allow science to follow evidence to...design no matter what the evidence turns out to be..it commits science to either having to deliberately ignore major (possibly even observable) features of the material realm or having to refrain from even considering the obvious and only workable explanation, should it turn out that those features clearly resulted from [intelligent] activity...any imposed policy of naturalism in science has the potential not only of eroding any self-correcting capability of science but of preventing science from reaching certain truths. Any imposed policy of methodological naturalism will have precisely the same potential consequences." p123-124"
