    Maybe I am misunderstanding you, but it seems to me that cognition
    has *some* spatial elements to it. I think more three-dimensionally
    and my husband is a linear thinker. I've always seen this as a
    left-brain/right-brain thing. Or maybe space is the best analogy
    that we can find to describe a connective pattern.

    Dispensing with the spatiotemporal lends itself to the concept of
    abstraction. I had never thought of that before.

    I have wondered about the process of memory decay. I could never
    reconcile it with Penrose (the canadian surgeon) who stimulated
    certain portions of a person's brain during neurosurgery and got them
    to reproduce quite mundane memories. I think he might have been the
    originator of "engram" and the concept of holistic memory, but don't
    hold me to that.

    Are you suggesting that these "nerratized and abstracted remainders"
    might be somehow related to memes?
