There was a story many years ago about an artificial intelligence that was created to aid researchers by absorbing knowledge in many fields. It would digest the information for a researcher and see if anything it found in other areas would be useful to the researcher. The prototype A.I. was visited by a priest in order to determine if it had a soul (if not, it could be turned off and duplicated, so it could be marketed to the world). I thought the title of the story was "Ariel" (the name of the A.I.?), but have been unable to locate it though the web. I also thought it was in Omni magazine (or one of the collections from it) but it does not show up in any index I can locate.
Anyone know the story, the title and the author (and where it could be found)?
