Now for my call to inaction: most scientists will concede that as powerful as science is, it can teach us nothing about values, ethics, morals or, for that matter, God. Don't go about pretending otherwise! For example, science can try to predict how human activity may change the climate, but science can't tell us whether those changes would be good or bad.
Should scientists, as humans, make judgments on ethics, morals, values and religion? Absolutely. Should we act on these judgments, in an effort to do good? You bet. Should we make use of the goodwill we may have accumulated through our scientific achievements to help us do good? Why not? Just don't claim that your science tells you "what is good" ... or "what is God."
Act: fight to keep intelligent design out of science classrooms! Don't act: don't say science disproves intelligent design. Stick with the plainest truth: science says nothing about intelligent design, and intelligent design brings nothing to science, and should be taught in theology, not science classes.
My value judgment is that further progress in science will be good for humanity. My argument here is offered in the spirit of trying to preserve science from its foes--but also from its friends.
