X-Message-Number: 10422 From: Date: Sun, 13 Sep 1998 13:12:34 EDT Subject: optimism Thomas Donaldson (#10410) and Jeff Davis (#10418) have provided important reminders or/and news relevant to potential information retrieval in cryopreserved (and perhaps otherwise preserved!) brains. Thomas points out again that most of the information in the brain is generic rather than individual, and therefore not critical. Mitochondria, for example, can be replaced as needed, and it wouldn't matter in the least if an individual mitochondrion were completely scrambled, or even most of them. Also, the connectivity of the neurons in the brain, a matter of primary importance, is at a higher level; it is related to not just one but several kinds of traces; and it is apparently mostly highly redundant. All of this is encouraging, although of course not conclusive. Incidentally, although most of us, most of the time, appear to take for granted the continuing contributions of many individuals, such as that of Dr.Brown in maintaining Cryonet and of Dr. Donaldson in publishing, editing, and mostly writing Periastron, that doesn't mean we really don't appreciate those contributions. I consider my Periastron file a very valuable resource, and hope it continues for a long time. Jeff Davis provides fascinating new information about the detailed workings of neuronal nets, including again strong references to heavy redundancy and to survivability--yet again very encouraging, although not conclusive. As to the appropriate balance of optimism/caution, either from an individual or a public relations standpoint, that is not as simple as it is sometimes made out to be. The dangers in encouraging complacency are obvious. We need all the continuing help we can get, hopefully more contributions of work and money from existing members, both for the organizations as such and for the research. Ideally, that would be proportional to the potential risks and rewards--but that perceived range varies enormously from person to person. The dangers in discouraging optimism are also obvious. Without some minimum of optimism--again, varying greatly among individuals--we will have nothing. Since we are still in the very early stages of growth of cryonics, it should be abundantly clear that, among the general public, there is no surplus of optimism. On balance, then, it is clear in my mind that we need to encourage optimism. For me, that is easy, since I believe there is ample objective reason for optimism, even in adverse circumstances. Is it possible and desirable to take a bifurcated approach--give potential recruits the impression that their chances are good, and simultaneously tell existing members that unless they pay up big time their chances are minimal? Hardly. Realism must rule. I believe optimism is realistic. In any case, realism requires that we take what we can get (while continuing efforts to get more). To quote G.B.Shaw, only a fool sacrifices the good in quest of the best.
