X-Message-Number: 8723 From: Thomas Donaldson <> Subject: Re: CryoNet #8708 - #8716 Date: Wed, 5 Nov 1997 23:53:28 -0800 (PST) Hi guys (and girls, and whoever else doesn't fall under those headings): I believe that Charles Platt suffers from a major misconception about cryonics, though Bob Ettinger should really be the first to answer him. NO, we do NOT advocate freezing people now as a means to raise money to perfect freezing at some time in the future. NOT AT ALL. Cryonic suspension would remain worthwhile whether or not we could do much research to improve it NOW at all. It would even remain worthwhile if the total number of cryonicists remained at its present low state for centuries. We advocate freezing people now because we believe that the current knowledge ofmedicine and all other abilities that we have bearing upon reviving and preserving people constitute only the slightest shadow of what they will someday become. Rather than decide that someone is "dead" (whatever that may be!) and therefore see that they become truly destroyed and therefore most certainly DEAD, even as cryonicists see it, we think it is far more modest and wise to try to keep them around, as well preserved as we can. We can right now only form the vaguest of ideas about just what doctors of the 23rd Century or the 24th Century or the 70th Century (remember how in PROSPECT OF IMMORTALITYEttinger describes how long someone will last given the physics of freezing in liquid nitrogen?) will be able to do to revive him. It is this which makes cryonics very much NOT the same as suspended animation. With suspended animation we know beforehand that we can revive this person. With cryonics we do not. We preserve the patient because we know just how little we really know. I myself have advocated that we do scientific research to improve our means of preservation. I do not believe that we, as cryonicists, should be content to simply wait for the future. At the same time I have said, and said many times, that cryonics should (and I believe will) continue into the indefinite future. That is, we will NEVER know all we can know about medicine, the universe, or any other subject: not in the 23rd Century, the 24th, or the 70th. To BELIEVE that you know all of anything is the beginning of stagnation, not the end of knowledge. And yes, the time between the 30th and the 50th Century may well be a time of stagnation. So long as cryonics societies survive in any form, then they can at least remain awake to all the questions that remain unanswered in medicine or elsewhere, and ready for the 70th Century when it arrives. I have even said repeatedly that it is CRYONICISTS who will ultimately find out how to revive these patients. Those cryonicists may not be anyone now living (though I would like such projects as Prometheus to succeed, Prometheus won't solve all our problems with suspension). But who else would even try? But when I talk about reviving suspension patients, I do not mean just those suspended under the best conditions. I mean every suspension patient for whom the information required still exists, even if in some unknown (presently) unreadable form. It's easy as we go about our lives to feel pride at the achievements of scientists and think that our understanding, even of physics, has come close to completion. We hear from MDs, from scientists of all kinds, of how well their theories now explain so many things. At school we learn of some or all these theories, too, so that thinking in that way becomes almost automatic. Yet anyone who seriously reads and thinks about the history of science should (and I hope will) stop and think: someday ALL of this may be seen as completely false. Sure, perhaps an approximation to the truth we NOW know, but only a poor approximation... How can that happen? Because the fundamental ways we now think about matter, energy, life, all those other things, are tied in closely with our "knowledge", and stand or fall along with those theories. Here is little history of science. You see, Galileo was far from the first to think about moving bodies and how they moved. Many people before him were troubled by this problem. But it was Galileo who introduced the notions of TIME and ACCELERATION, which ultimately helped to explain them within our current physics. Explain? Predict. Sometimes, hardly always. And this happens in medicine too: in the last 20 years we've seen the dogmas that nerve cells can never be repaired, and people ischemic at room temperature for more than 5 minutes can never be revived, fall into many research questions rather than remain standard truths. Without the notions of time and acceleration the entire theory of simple physics cannot exist. And so long as we think in terms of the physics we all learned we will fail to see the physics of the 24th Century, or the 70th. Or the medicine of those times, either. WE DO NOT LIVE IN A TIME FUNDAMENTALLY MORE KNOWLEDGEABLE THAN ANY OTHER. That is the root point which cryonics explicates by cryonic suspension: just why we freeze pieces of brain obtained from the coroner, or freeze people found only hours after their "death", or all the other acts which may puzzle those who believe in current medicine so firmly. And to really convince someone of cryonics, they must come to understand how ignorant we all are. I hope someday that this will be seen as a common truth that need not be explained; and when that day happens, we'll find the majority of people to be cryonicists. As to when that day might come I cannot say. Long long life, Thomas Donaldson Rate This Message: http://www.cryonet.org/cgi-bin/rate.cgi?msg=8723
