Alister McGrath makes some interesting comments on the need for prediction in science, noting that a natural theology may be possible on the basis of accommodation within an ‘inference to the best explanation.’ He writes;
‘…some theories concern entities or situations in which predictions may seem inappropriate or simply impossible. If natural theology rests primarily upon accommodation [and not prediction], it is in good scientific company.’ McGrath, (2009) A Fine Tuned Universe, Louisville: Westminster John Knox, p.60
McGrath is still a keen Darwinist and not really a friend of ID, but it does imply that ID can be justified on the basis of accommodation and need not necessarily seek justification on the basis of explanatory power.
