am a theist, so my habits of mind have a particular character. Such predispositions, long typical in Western civilization, have been carefully winnowed out of scientific thought over the last two centuries in favor of materialism, by which I mean a discipline of exclusive attention to the reality that can be tested by scientists. This project was necessary and very fruitful. The greatest proof of its legitimacy is that it has found its way to its own limits. Now scientific inference has moved past the old assumptions about materiality and beyond the testable.
