The Second Law of Thermodynamics, that entropy is increasing (or "you can't break even") may apply, but it does not preclude the recovery of information from an isloated system. It means, however, that you may have to work very hard at it, and be lucky as well. But in a practical sense it seems to me that information is lost, even if not in an absolute sense--you just aren't going to be that lucky. One topic of debate right now is whether black holes would destroy information in an absolute sense, some holding they would (which would be problematic for quantum mechanics), others invoking concepts of string theory to argue they wouldn't. >I also agree with Leon Dean, Message #11454, that there is no reason other >than selfishness for cryonics. I strongly disagree with this, insofar as "selfishness" is usually understood. Cyronics can (and should) be practiced for other than narrowly selfish reasons. I even think that *enlightened* self-interest, expanded to the scale of a much longer life than is possible today (and hopefully eternal), will fully reconcile egoism and altruism. (Thomas Donaldson expresses some thoughts along this line too, #11464). With proper orientation and action, one can *benefit* others, and thus securing one's presence can be seen as doing others a favor. Perhaps this will sound facetious and a weak rationalization of simply wanting to save one's hide. But it doesn't have to be. It can be taken quite seriously and literally--I recommend making the effort. The benefiting too has a self-interested basis; one expects reciprocal benefits in return, as is certainly reasonable. > For civilisation to not stagnate, it >depends on >change and evolution. Mike Perry, Message #11463, suggests that >'primitive' >individuals will be 'upgraded' to the latest specification. I think that >this superior >intelligence will not be the same person, apart from sharing some memories. > Again, I strongly disagree, though this kind of attitude seems a common one. It is *possible*, as I've found from personal experience, to regard an earlier stage of oneself as still "oneself" even when much time has passed and many new experiences have occurred, including schooling, acquisition of new skills and knowledge, etc. In the future, as I see it, the self-improvement process could take many forms, ranging from simple education to radical physical changes. There will not be "the" latest specification to which persons are "upgraded" as if some outside agency determines the "specifications" and then allows or requires people to adjust accordingly. The upgrading instead will be self-initiated. People will determine the "specifications" they wish to upgrade to, and advance accordingly by elective choice, a different choice and different mix of enhancements for each individual. >Sir Arthur C Clarke says that we change throughout our lives anyway, and I >agree with him totally. We change, but not necessarily so much as to become really different persons. "The more things change, the more they stay the same,"--in some ways at least. Clarke, in some ways and for some people, is horribly mistaken. > You would have to actually be religious and >believe in a >supernatural unchanging soul, to think that an upgraded version of yourself >would >be the same person. > Not quite. Another idea that supports the "same person" concept is that of convergence to an ideal self, a process that would take infinite time overall and involve unlimited advancement. This is a somewhat complicated idea to explain; email me privately if you are interested. >The relatively new theory of memetics suggests that the very concept of >self is >an illusion - merely the result of Darwinian evolution of so called memes. I don't see the concept as an "illusion." I think it has (or can have) logical coherence, even if many people themselves are not too consistent in what they think of as the "self." >The >concept of a conscious self is a powerfull meme for obvious reasons.

I don't think we have true free will either, but that does not destroy the concept of self, which I think can be developed on informational (and reductionist) grounds, without assuming any mystical soul or free will. >Having said all this, I am not against anyone who wishes to be preserved, >and I >wish the movement well.
