X-Message-Number: 18013 Date: Sat, 24 Nov 2001 07:27:19 -0500 From: Thomas Donaldson <> Subject: CryoNet #18007 - #18012 To Mike Perry: No, what you say does not obviously deal with the problem of duplicates. In the first case, we are really discussing whether we must replace part or all of our patients' brains to reawaken them. Once we assume first that we work by known physical-chemical means, and second that we can indeed replace these parts, then the degree to which we must replace parts becomes a minor issue. Where is the duplication here? A restored patient is no more a duplicate than I am a duplicate of myself 1 year ago ... much less than that, actually. In the second case you discuss, you aren't really discussing bringing someone back but creating another (or many) versions of an existing person. I'd tend to say that each version becomes different, given that they're in different places (and if all those places are identical, then why bother?). There is an issue of identity here. However whether or not we want to do this after our revival remains a separate question, and it has no bearing on our actual revival. I'm not saying that these questions cannot be interesting. I'm just saying that they seem to have virtually no bearing on cryonics itself.
