X-Message-Number: 4654 From: Date: Thu, 20 Jul 1995 13:50:40 -0400 Subject: emphases Probably too much spacetime has been wasted on the non-question of suspension research vs. repair potential. We are probably all in essential agreement, with differences of emphasis. Even so, I'll make this response to Thomas Donaldson's #4650. First, it shouldn't be necessary to cross every t and dot every i. When I mentioned die casting, I was referring to ordinary symmetrical dice and not possibly loaded ones. My point was valid--that in most cases the broad sweep of historical evidence is much more important than any individual datum of observation. In fact this valid point--or a misapplication of it--is one of the reasons for the failure of cryonics to gain much acceptance so far. A subset of the sweep-of-history principle is that the traditional wisdom is usually right, which implies cryonics is wrong. The problem here, of course, is that the skeptics are looking at the wrong subset and don't really understand the principle; they are merely obeying habits and not really reasoning at all, or not reasoning carefully enough. Thomas mentions that optimistic speculations have often proven wrong. So have I, with specific examples; I am not a short-term optimist. In particular, although I hope I am wrong, I am not optimistic about early perfection of reversible-on-demand suspended animation, even for the brain alone. (For the umpteenth time, this does not denigrate the importance of research, but underlines it.) The difference of emphasis is that Donaldson and Darwin and others fear insufficient support for research--too much complacency about future repair capabilities. They don't want too much optimistic speculation about nanotech and cryptanalysis etc. (Incidentally, when I mentioned the wide view in relation to cryptanalysis, I didn't mean to imply that Merkle had no specifics to offer; he did, even if not enough to complete a "syllogism" to Donaldson's satisfaction. ) But some of us think that investigation into nanotech and inference technology (whether or not very detailed and closely relevant to brain biology) is highly desirable, both for the impetus to actual technological advance and also for its psychological effect. Again: A few people may be overly complacent. A few may be in cryonics for the wrong reasons--starry-eyed and uncritical worship of science-writers' science. But against this is the overwhelming mass of people who "want an automobile that runs" (in my father's words) and will not buy one that almost runs--not at any price. These skeptics pride themselves on hard-headed realism--an exaggeration or parody of the Donaldson/Darwin position. "Show me; I'll believe it when I see it." But this is NOT realism. One is reminded of the saying in Israel: "Here, whoever does not believe in miracles is not a realist." (Yes, that saying has become a bit frayed lately.) Realism not only excludes uncritical acceptance of fantasy; it also INCLUDES reasonable extrapolitions and acknowledgements of the remarkable accomplishments of the past. Have any of the goals of science or technology proven unattainable? On a short term basis, yes--no flying flivver after all this time, to use my well-worn example. But none, to my knowledge, has been ruled out with finality. (And of course many new areas of achievement have opened up that were previously undreamed of. This ALSO is a central element of realism.) The relevance of a datum is more important than its accuracy. Feynman suggested atomic manipulation of matter; the implications of this far outweigh most particular findings about the anatomy and physiology of the brain. Some people think it is impossible to read a page that has been torn up, so they shred documents. In fact, it is sometimes possible to read a page that has been BURNED up. Cryptanalysis is not irrelevant and should not be disparaged. Some think that all the information about your brain can only be found IN your brain. In fact, you have impacted your environment in countless ways, and it will almost certainly become possible to infer massive amounts of information about your fine structure just from the public written records in conjunction with your own genotype, writings, photos, videos, audios, and the memories of your acquaintances. All these things TAKEN TOGETHER will almost certainly converge to fine specifics. If you want some further far-out possibilities, look at some of Yvan Bozzonetti's stuff. For that matter, many of the consequences of the currently dominant interpretations of quantum theory are far from established. How reconcile uncollapsed wave states with universal gravitational interactions, as one small example. (Has anyone important ever suggested that Newton's Third Law implies that no system is ever isolated? ) Or how do we reconcile a fixed past with a blurred present? Or how can we confidently dismiss the "still life" view of spacetime as all laid out in one continuum, past/present/future coexisting? How can anyone seriously claim that we are out of kindergarten when we know NOTHING about the physics of time? A few centuries ago MOST of the physical universe and MOST of its phenomena were totally unkown--e.g. only the visible part of the electromagnetic spectrum was known, and only a tiny part of the sidereal universe and only a minuscule fraction of its history. For all we know, this may STILL be true. The difference between cryonicists and others--at least on the intellectual level--is that we try to look at the big picture. What is important? Your life, and those of the people you love. How can we save and improve ourselves? By applying ALL of the means at our disposal now and in the future, and by working to shift the odds in our favor. Forgive the rambling. I don't think I'll dwell any further on this topic any time soon, unless I think of cleverer ways to say it. Bottom line: skepticism is a MUCH bigger problem for cryonics than is complacency. We need both direct, immediate suspension research and broader, more remotely targeted work toward nanotech and inference technology.
