X-Message-Number: 2701 Subject: CRYONICS Philosophical Issues From: (Charles Platt) Date: Tue, 26 Apr 94 01:15:27 EDT I didn't comment before on the philosophical issues raised here, because for me they don't apply. It is easy to explain, however, WHY I feel they don't apply. People who fall into snow drifts or drown in cold water have been revived after periods of more than three hours of zero detectable brain activity. To me, this doesn't seem qualitatively different from resuscitation after a period at below-freezing temperatures. Since resuscitated patients do not seem "soul dead," it seems tempting to conclude that cryonics cases would be no different. Of course, it is possible that a resuscitated person is not, in some sense, the SAME person as before. Identity may in fact change, and this may be subjectively undetectable. If it is undetectable, however, there's not much point in worrying about it. I feel that it is still conceivable that a "soul" exists, but if it does so, it must derive from structure, or pattern. This would be the only way to explain why a resuscitated person with little brain damage seems the same as before, while a similar patient who does sustain brain damage loses his or her "life force," if such a thing exists. By this reasoning, if a living person has a soul, a frozen person also has a soul, except in cases where the damage prior to freezing was severe enough to destroy the "soul supporting" structure. Ralph Merkle would probably argue that even if the structure is largely destroyed, it may still be possible to reassemble the component parts. This would suggest that a soul could be reconstituted. But since this discussion entails at least two unprovable assumptions, both of them stretching credulity, I see no point in taking it any farther. Really this is all quite half-baked, for a which I apologize. The best argument still seems to be that until anyone can prove some loss of identity or of "soul" as a result of freezing, cryonics remains a better option than any of the usual alternatives. --CP Rate This Message: http://www.cryonet.org/cgi-bin/rate.cgi?msg=2701
