As a new reader and poster, this is one of the first threads that I've read through carefully. I'm impressed, first by how the discussion seems to devote itself as much the rules of rhetoric as to the subject itself.
On subject, I've recently read a light little novel entitled Friends, Lovers, Chocolate by Alexander McCall Smith, which has cellular memory as an important plot element. The characters (and presumably the writer) concluded that the traumatic experience of receiving a transplant can be the cause of the sometimes intense delusions and character alterations we call 'cellular memory'.
It's easy to understand how these internal disturbances can be laid to 'cellular memory' by persons struggling to rationalize their subjective responses to such a recent development in medicine as whole organ transplants.
It's easy to see how one can make the intellectual leap to a conviction that the 'new part of me' is a psychic as well as a physical addition to my Self. And self-delusion does the rest.
I ponder the fact that yesterday I ate a delicious beef hamburger, which is now presumably thoroughly 'incorporated' into my slab sides; yet I feel no impulse to low, graze, or pursue that cute heifer in the field.
But...I'm also constrained to remark that transplanted kidneys remember how to secret urine, corneas to see, hearts to beat, and livers to errr......live. So in a sense, cell memory IS an undeniable fact. But memory resides in the brain, if we are to believe neurological dogma, and the notion that the heart remembers love, or the eyes the image of one's murderer: notions common in romantic literature, are archaic superstitions. Anyone for a slice of Einstein's brain?
