    I think the current consensus is that it was an interesting theory,
    but turned out to be wrong. It's pretty much discounted among
    faceters now. One of the other faceters on the list might have some
    references at hand. If not I'll try to dig up some. I'll also look
    for an article that I remember written by Dr. Stephen Attaway,
    describing another theory of polishing. 

    The basic problem is that the "finer and finer scratches" theory of
    polishing doesn't fit well with facts like polishing quartz and
    beryl with CeO2, which is softer. That's why we have people
    theorizing about why it works so well.
