X-Message-Number: 2709 Date: 28 Apr 94 19:43:53 EDT From: Mike Darwin <> Subject: SCI.CRYONICS Dreaded Subject Sometime back Ben Best expressed surprise at how few people had taken up the challenge of discussing "the nature of identity." I can only speak for myself, but I have shown restraint so far for several reasons: 1) I have been very busy. 2) I wanted to wait and see what others said and only then add my two cents worth -- if I had anything I thought worth adding. 3) I knew Ben had only to wait a little while: Mention of the word "identity" around a group of cryonicists is like mentioning the word "irregularity" in a nursing home (a mistake I have made): be prepared for an avalanche of discussion, rumination, opinions, deep convictions, and firm pronouncements about both causes of, and solutions to, the problem! So what do I have to say about what has been said so far? Well, first I would like to compliment Bob Ettinger on his cryomsg 2707. I believe much of what he had to say there was *wise* which is very different from being merely "correct" or even "clever." Being a cryonicist of sorts I too have given a great deal of thought to this problem. I note that others who were not cryonicists have thought on this problem too, and at the risk of perhaps boring or distracting you I would like to quote one such: "Who are *you*?" said the Caterpillar. This was not an encouraging opening for a conversation. Alice replied, rather shyly, "I-I hardly know, sir, just at present--at least I know who I was when I got up this morning, but I think I must have been changed several times since then." "What do you mean by that?" said the Caterpillar sternly. "Explain yourself!" "I can't explain *myself*, I'm afraid, sir, said Alice, "because I'm not myself you see." "I don't see," said the Caterpillar. "I'm afraid I can't put it more clearly," Alice replied very politely, "for I can't understand it myself to begin with; and being so many different sizes in a day is very confusing." "It isn't." said the Caterpillar. "Well, perhaps you haven't found it so yet," said Alice; "but when you have to turn into a chrysalis--you will some day, you know--and then after that into a butterfly, I should think you'll feel it a little queer, won't you?" "Not a bit," said the Caterpillar. "Well, perhaps your feelings may be different," said Alice; "all I know is, it would feel very queer to *me*. "You!" said the Caterpillar contemptuously. "Who are *you*?... The above is from *Alice's Adventures in Wonderland* by Lewis Carrol. Having considered the problem of identity for most of my thinking life (having been involved in cryonics for same) I have more than a little sympathy for Alice (but some for the Caterpillar too!). The problem with the idea of a "self circuit" (SC) as a determiner of identity is not that such a *selfawareness* circuit does or does not exist (since we are self aware and self awareness is apparently a property of the arrangement of the atoms in our bodies then some such arrangement, pattern, or circuit; discrete or distributed, probably exists). The problem is, "is conservation of such an SC either both necessary and sufficient to insure conservation of "identity?" I raise this issue because of an apparently casual remark made by the gerontologist Bernard Strehler many years ago. He mentioned in passing (while musing about identity and the quest for immortality) that humans and presumably other phylogenetically close species probably posess a basic sense of "I think and feel; therefore I am," and that memory and individual variation of experience was just so much icing on the cake of the universal experience of being. Years ago I took a course on Transcendental Meditation (TM) from disciples of the Marahishi Mahesh Yogi, the objective of which was to reach a state of "pure consciousness," in other words a sense of being uncluttered by any *particulars* of time, place or memory: To experience pure *being* or to use Bob's words, to experience the "self-circuit" in isolation from any other experience. This was to be achieved by closing one's eyes, sitting or lying in a quiet place and repeating a "mantra" (special sound) over and over again. Given the Maharishi's recent claims of flying, creating world peace, and who knows whatever else kinds of goofy stuff via TM it will probably come as a surprise that I would have anything positive to say about it. In fact, I do. In one important respect it did what it was advertized to do: after prolonged experience with the technique I (and I believe many others) were able to reach a subjective state best described (by me at least) in the more prosaic terms of *being* without particular thought, distraction, motivation or awareness of anything other than merely being. One reason TM (by some fairly good, well repeated objective studies) drops stress levels, reduces cortisol secretion, etc., is that a lot of everything else associated with being alive other than the "pure" feeling of being is most unpleasant. I remain unconvinced however, that experiencing "pure consciouness" or a one-on-one with the SC is the answer to world peace, flying without airplanes...or the solution to the problem of identity! It is interesting to note that the Maharishi's claims about the SC are much the same as Strehler's musings: the experience of pure consciousness is a UNIVERSAL human phenomenon and is generic. Strehler's conclusion was that perhaps we should take some comfort from this realization because even if WE die, the essence of personhood, the SC, will go on in others as long as the species survives. And if immortality IS achieved, we will have a piece of it, will have it in fact, because WE are the SC and the SC will have immortality. Is this right? Hmmmmm. I think that looking to the SC as the source of the soul or the *essence* of identity is a lot like looking for "automobileness". There are many different kinds of automobile and clearly a Ford Pinto is NOT a Lamborghini Countache (sp?) (although I might add that both are equally uncomfortable to ride in as passengers!). Is it the presence of pistons that makes a car a car? What about Wankel engines? But more to the point what makes a *particular* car a particular car? We can of course iterate all the salient features and even with proper tools more or less duplicate them. (This raises the ever present bugaboo of duplication: how can *two* of you be you?) Clearly the arguments about the limtations to memory as the essence of identity seem to have real merit too. A can of CDs with all my memories is not me. And maybe even a computer simulation running those memories on a "nonbiological" copy of my brain hardware isn't me either. These are tough questions. While I, like Bob, have come to no firm or ultimate answers, I do have some opinions at this point: * Looking for some ONE THING like the self circuit to call the soul or identity is probably like looking for the holy grail or the philosopher's stone. People aren't just an SC or their memories, or this or that in isolation... They are ALL of those things. * Identity as we *feel* about it or intuit it may be illusory. If we aren't any one memory plus everything else, which ones are we...? * The above notwithstanding, the longer I live and the "weirder" physics appears to be getting the more credence I give to the idea that continuity, perhaps related to space-time as Bob speculates, may have something to do with it. Heinlein described a person as sort of being like a worm or a wave function through space time in a story he wrote about a scientist who built a machine that could tell exactly when someone was going to die. * The last point above notwithstanding, identity may be best expressed (from the information-theoretic standpoint) as a fidelity curve. Clearly at some point on that curve a person as we understand personhood goes away and at some point BEFORE that point a particular person (given a somewhat arbitrary and coarse-grained set of parameters to describe the particular person by) goes away. Again, a machine analogy is an apt one: if you take the hood ornament off the car it probably is no big deal to the car's "identity" in a functional sense. But if you take the engine out, whoa! People may be much the same. If I wake up from suspension and I can't remember a damn thing about music it certainly won't be the end of the world for me. Most music merely irritates me and I spend relatively little time listening to it for pleasure (I do not even own a "stereo" or CD player). On the other hand, if I were Igor Stravinsky and I woke up knowing nothing about music that might be a very serious problem. (As for me art is another matter altogether. My home is jammed with art books, prints, posters, sculpture, pottery and so on. My visual sense is very important to me and probably a critical element in my identity.) Nor is this kind of thing unique to cryonics or recovery of patients from cryopreservation. The neurologist Oliver Sacks deals with this problem quite nicely in his book *The Man Who Mistook His Wife For A Hat*. People suffer all kinds of injuries today which depersonalize them and in some cases probably erase who they were by all but SC criteria. I remember watching an Oprah Winfrey show while shopping at Price Club; I ended up riveted to the screen in the store for the whole of the show. The subjects were men and women who had suffered TOTAL amnesia after head injury but gone on to make more or less a full functional neurological recovery otherwise. The amnesia in these cases was global and "permanent", the shortest time anyone had been an amnesiac was, as I recall, 5 years -- several were out 15 years or more. A few had recalled a vague memory or two, but most were totally amnesiac. One woman described feeling horrified at the advances (sexual) of this strange man who claimed to be her husband...(they had been married for many years). The stories were all more or less the same: these people knew NOTHING of who they were. In some cases marriages of long-standing dissolved. Some of the amnesiacs experienced major changes in personality, often becoming gregarious and disinhibited and far more socially functional (this is a common side effect of head injury (and Prozac): it is no accident that Roseanne Barr went from a shy withdrawn mouse of a girl before a head injury as a teenager to the wildly extroverted, foul-mouthed (and I might add highly creative and entertaining) person she is today. The cap of the show for me was when Oprah asked a very insightful and profound question to both the "victims" and their families: "Do you feel you (or your relative) are the same person as before the accident?" The answers were divided but it was my impression (this show was years ago) that most said "No, I (s/he) is not the same person." One husband and wife had to "fall in love all over again" and in fact the husband noted that this woman with whom he was now living was not at all like his former wife (whom he admitted to still "mourning"). (Imagine being married to a quiet, thin, prudish and very shy small town librarian and after her head injury in the stacks you find you've taken home Roseanne from the hospital!) The point here is simple: SC conservation or no, such a change in a person (complete loss of memories, change in appearance (i.e., weight gain due to lusty disinhibition and newfound gluttony for food), hypersexuality, a complete change in temperament) would strain the credulity of even the most conservative that this was indeed the same person. And listen folks, this happens right here today, WITHOUT cryonics. The problem certainly exists for those people who were on Oprah and for their families. Perhaps the most disturbing thing about the Oprah show was that it demonstrated that head injury under some circumstances appears to be able to permanently either erase declarative memories OR access to them. I suspect it is the former rather than the latter. But that is another subject alotgether. So where does all this leave us? "So you think you're changed, do you?" "I'm afraid I am, sir," said Alice; "I can't remember things as I used--and I don't keep the same size for ten minutes together!" "Can't remember *what* things?" said the Caterpillar. "Well I've tried to say 'How doth the little busy bee,' but it all came different!" Alice replied in a very melancholy voice...." Alas, poor Alice, I know exactly how she feels.
