Its interesting to note that Dawkins has gone from a flat scientific affirmation of Atheism, to the more reasonable attitude of Agnosticism. We must think that this change of mind has been caused by the terrific intellectual headwinds he has been bucking by attempting to pass off a statement of faith (as A-G describes it) as a scientific fact of ontological certitude.
Dawkins has done this before (retreat from an Atheistic attitude to a more moderate Agnostic perspective), so dont be surprised if you find him back later at the same old Kool Aid stand, selling the same old Atheist Kool Aid on the same old street corner.
Thank you so much for your insights, dear YHAOS!
