X-Message-Number: 4996 From: Date: Mon, 16 Oct 1995 00:02:35 -0400 Subject: nearly-full glass In recent postings Mike Darwin relates evidence of survival of Hossman's cat after an hour's brain ischemia and of mice after partial freezing damage to the brain, but with memory or cognitive functions impaired; and John Clark reminded us of Merkle's calculation that freezing damage probably does not entail turbulent changes in the brain, more or less contrary to Mike's impressions. Mike seems to feel that a walking-around, normal-acting cat, since it may have extensive hidden deficits, leaves us with a glass half (or more) empty. Contrariwise, I see this as very hopeful, with a glass half (or much more) full. The point is that memory and cognitive functions are PERIPHERALS; the central self is far more important, and that almost certainly survived in these cases. The central self--the self-circuit or subjective circuit--is the part or aspect that feels and experiences; it is the ground of being. In these referenced animals, and in many human clinical cases, there can be very severe memory/cognitive impairment, but nevertheless unquestioned survival as an individual. In other words, YOU are much more hardy --including freeze-hardy--than some of your functions and stores. Certainly your memories and connections are important to you, and to some extent may even be said to "define" you as a person. Some people would even prefer permanent death rather than substantial loss of memory. Some (they think) would even prefer death to revival "alone" in a "strange" world. Granted that the "philosophical" problems are unresolved, and we don't yet know whether a continuer or partial continuer, or a duplicate or partial duplicate, would "really" be you, or whether we are even asking the right questions. But I know that I have largely lost my early selves, and I don't mind too much; I assume my distant future selves may have little in common with my present consciousness, and that doesn't bother me either (which doesn't prove it shouldn't). I do not identify myself too strongly with my memories, or my habits, or my environment, or my history--all that is baggage, and I can always get new (and hopefully better) baggage. If "I" can be revived as a living, feeling entity, and if appropriate peripherals can be attached, I don't think "I" will sweat over fidelity or authenticity. Once more: Mike and others seem to think that we must restore the brain by inference from its remains, basically using trajectory-tracing, and that any substantial failures would be disastrous, and that "homegenization" is equivalent to destruction. High-fidelity preservation is an extremely laudable goal, and MIGHT turn out to be essential, granted. But there is MUCH more in our potential armamentarium than trajectory-tracing--there are countless history-anchors in the private and public records--and in any case the traveler who has lost his luggage (however valuable and lamented) has not perished.
