>>Though there are indeed many like Mr. Weisberg for whom this little-recognized truth (our deepest truths and most passionate convictions cannot always be made to work together) remains so, there are others for whom it is a foundational insight upon which all their subsequent reflections tend to rest.<<

Your argument rests on the assumption that it isn't possible to have a philosophy in which all the most important truths are compatible. I reject this assumption. A world view based on physics and evolutionary biology is completely compatible and consistent. Theist like to talk about the beauty of the physical world and its interconnectedness as evidence of gods handy work while ignoring that science has developed independent fields that also interconnect and have formed a single unified explanation. Just one of the beauties of this belief system is its comforting consistency.
