Ah. I see. I've read very little material from the Catholic vein. My interests ran more to the Eastern religions, some mystical stuff about Chrisitianity, and the North American Native religions. I started out the whole process in my teens as a 100% atheist, but that changed after awhile.

You might find Sri Aurobindo interesting. He was a man of absolutely enormous intellect and education. He's as comfortable with science as with spirituality, and he also was a confirmed atheist in his youth.
