X-Message-Number: 8848 From: Thomas Donaldson <> Subject: Re: CryoNet #8828 - #8839 Date: Wed, 26 Nov 1997 00:35:29 -0800 (PST) Hi again! To Paul Wakfer: I've already contributed my $1000, and intend to keep it up (and if not promise to tell you why). And yes, complete suspended animation would provide a big advance in cryonic suspensions (given that everything needed is set up in advance). I too want that to happen, as fast as possible. HOWEVER we have no more reason to believe that we will survive sleep (ie. we'll have the same sense of identity) than we have to believe that after lots of highly advanced repair we will survive cryonic suspension. Sure, we can do lots more neuroscience to explain a sense of identity FROM THE OUTSIDE, but what it feels like to be the same person as you were yesterday, and FEELING THAT, is quite different. I can only look at you from the outside, and the same is true about you. The most we'll ever be able to do is to show that our restored patient has the same continuity as someone who awakens after sleep... as seen from the outside. One major problem cryonicists have with "death" comes exactly from this. Most people do not think it is just a physical condition, they think it is metaphysical. And if we tell them we'll be able to revive them "after they have died", then they may even agree --- but add that the person revived is not and cannot be THEM. Certainly there are cases in which destruction has been so very great that whatever we revive may only resemble them in so a fuzzy way that even we, from the outside, would say that at best we have an approximation; but the possibility of much more perfect revival and repair remains, too. In practise, such problems are ignored once we know how to do the repair. Right now doctors are learning how to revive someone after 15 minutes rather than 5; no one claims that people revived fail to be the same person. Yet when we raise the possibility of a FUTURE time in which such abilities extend up to several hours, and can involve considerable damage due to freezing, then it's easy for people to fail to make the leap. If you are "dead", your "soul" is gone. Metaphysics cannot be answered by science, it can only become outmoded. As an instance, I remember vividly a big accident over 15 years ago. It was winter, in Washington DC, and a passenger aircraft failed to take off, crashed into the icy water, with only a few survivors. Yet many passengers were floating amid that ice. How many might have been rescued if more of their rescuers understood the effects of cold, we'll never know. You see, they were all "dead" already. Why bother to revive them? I personally want to see improved cryonics technology (which would go so far as suspended animation, if we can) not because I doubt the eventual possibility of revival, given that I have been rescued from total destruction of my brain, but because of the dangers of helpless waiting that cryonics involves. I'm not referring to any world catastrophes at all, simply to the plain fact that accidents and political events can greatly affect my personal preservation during my suspension. If I must be preserved for 10,000 years there's a lot of dangers I will unknowingly face. Some people may actually remain in suspension that long, but most would not, by simple random attrition. Whatever shortens that period is worthwhile. And I'll add that I take the same viewpoint towards the Prometheus Project itself. It very well MAY "fail" in the sense that we don't learn how to preserve brains perfectly in 10 years; but we will also do a great deal to improve our suspensions. A way of preserving brains which left fewer areas as apparent tangles on electron microscopy --- that is an improvement. We won't be done until we leave NO such areas, but the less brain damage we cause now the easier it will someday be to work out how to fix that which remains. And please understand: I want Prometheus to succeed. But I also think that Prometheus CANNOT fail... though I'll add that I also think, with the people we've got, tht it has excellent chances of success in finding out how to preserve brains. To Saul Kent: First of all, I am very grateful, and I hope others are, of what you have done to push along research both in life extension and in cryonics. Of course I know you do it for yourself, also, but I remain grateful. However in your posting you seem to think I was directing what I said at you. I don't recall mentioning your name. As for arguments about the best way in which we can make cryonics grow, no one says you have to work that out TOO. In the long term, yes, research will be a very good way, particularly since I actually believe our research is likely to succeed, even in the basic simple sense of learning how to cryopreserve brains with no significant damage. Yet fundamentally I think the best of all reasons for research is how it benefits US. And I was directing my comments to others, who seemed to feel that its merits in recruitment overshadowed that fundamental benefit to US. To Will Dye: Glad to see you on Cryonet. I personally don't see anything wrong with simple "immortality". Isn't that what we really want? So why not say so and leave others to twist themselves into knots about it as much as they wish. Anyone who refuses to join because of the words we use has a much deeper problem (incidentally, you're far from alone in proposing we use a new word. I remember lots of such proposals. Somehow none of them ever stuck). and to all, Best and long long life, Thomas Donaldson Rate This Message: http://www.cryonet.org/cgi-bin/rate.cgi?msg=8848
