X-Message-Number: 7376 From: Date: Sun, 29 Dec 1996 11:42:20 -0500 Subject: For Anatole Dolinoff Anatole Dolinoff, despite his long and distinguished career in promoting and defending cryonics, has recently (Dec. 28) and at other times said essentially that he has no good ammunition against critics who cite the damage done by freezing and the lack of success so far in reviving large organs of frozen mammals. He has also repeatedly said that "Nobody knows if the chances [of successful revival of people frozen by current methods] are equal to zero." Looking first at this last statement, in my opinion it is not correct. We must carefully distinguish between the "possible" and the "probable." One could correctly say that we do not know whether revival is possible, in the sense that the laws of nature permit it. We CANNOT say that the probability (or chance) of success is zero, because probability relates to the state of knowledge of the observer. The "probability" of an event is zero ONLY if we KNOW FOR SURE that it cannot happen. (I leave aside certain refinements of measure theory.) Since we DO NOT know for sure that revival must fail, its probability is not zero. (In fact, I have published reasons to believe it is closer to unity--certainty--than to zero.) And this brings us back to Anatole's pessimism about offering persuasive arguments to skeptics (not all of whom, we emphatically note, are unfriendly toward our goals). In my opinion, he makes the mistake of letting them set the agenda. They simply say, in effect: "This project is extremely difficult, and we don't see how it could be done. Therefore anyone who involves himself in it must be crazy." The correct answer, of course (or one of them), is the one we have always given, with varying degrees of skill--certainly the difficulty is extreme, but the potentialities of future technology are also extreme. We can use the broad-gauge, common-sense view of past achievements, and past croppers of the pessimists; or we can use more specific, detailed arguments such as Ralph Merkle has done so well. It doesn't pay to be diffident in public discussions, to be seen as lacking confidence. We do NOT of course want to say, or seem to say, anything scientifically incorrect or anything in any way misleading. But we DO need to make our points with cheerful confidence, not conceding anything to a skeptic's alleged credentials. When we're right, we're right, no matter how many Professors say we are wrong. The "uncertain trumpet" will just not rally the troops. It also helps a great deal if we can point to research progress and catch the skeptics in factual errors, as we have often done.
