X-Message-Number: 25043 Date: Sun, 14 Nov 2004 14:57:31 -0800 Subject: Cryonics Implications of Souls (to Mike Perry) From: <> Dear Mike: You wrote: "Richard R, #25026, replies at length to my posting on souls (in response to his earlier postings), and raises some very interesting points which I want to reply further to--a particularly busy part of my week is starting up so I will defer for a little while. To answer one question, Richard, yes, I do work for Alcor." That's great, Mike! I have much respect for Alcor and their stated goal of improving the methods of cryopreservation, instead of assuming that future technology can solve any problem (because, no matter what technology can do, it cannot bring back the *same* soul, if it is destroyed; therefore, I consider it essential to develop technology capable of preserving the soul). I am signed up for vitrification and eagerly await the development of high temperature storage. I hope through these discussions (and writings that I will send separately to Alcor), I can influence Alcor to take an official stand on the uploading issue; and the broader issue, which is, what exactly can you do to the brain without destroying personal identity. Merkle's approach of disassembling and reassmbling the brain, atom at a time, using the exact same atoms, surely results in destruction of personal identity. People who undergo this process will never wake up again; it will be as if they were cremated. You wrote: "It might very well be convenient to split a cryopreserved patient into several or many pieces, work on the pieces separately (at low temperature, say, where unintended changes would be minimized), then reassemble the pieces and finally resuscitate the patient physiologically intact. Now, in your view, would such disassembly/ reassembly kill the soul within, so you'd just get a different individual?" It is clear from trauma that we do not need parts of our brain in order to function. In fact, I expect we could do without even larger parts of our brain, if our intention was just to preserve the soul (the qualia experiencer within). Therefore, I would say, there are ways to split the brain into pieces such that the soul is not destroyed. Since we don't know very much about the brain, I would say, we cannot know exactly what divisions are possible without destroying the soul. The question is answerable, but probably not for a long time. Being naive at this point, I would hazard a guess that you could probably split the brain into macroscopic chunks, repair the chunks, and reconnect them, without destroying the soul. But not knowing more about the brain, I would want to err on the safe side in reconstruction, and repair the whole thing as a unit, even if it were to take an additional few decades of computer-supervised work. "If you so much as split a brain into two pieces then joined them back, with full recovery of function, you could say that there was a time when 'you didn't have the person' thus the original is irretrievably lost. Is this how you view the matter? We can also consider the idea of splitting the brain into parts which, however, are still in contact via radio, as should be possible in the future. Is the person still present (assuming consciousness goes on as usual), and if this contact is briefly shut down then resumed, does that kill the soul?" Assuming there were a soul to begin with, my answer would be yes--- shutting down the communication kills the soul. However, I am fairly certain there is no soul to begin with. The soul dies the moment you split it into pieces, and cannot exist afterward even with the radio communication. The reason for this involves the subjective interpretation of the radio signals. For each split piece, there is a piece of hardware that translates the radio signals to neural inputs, and translates neural outputs into radio signals. This conversion of neural function into pure information, which requires both a medium and a subjective interpretive scheme, prevents the emergence of a system-wide soul. Now you might argue each little piece of hardware, combined with its neurons, constitutes or possesses a kind of soul, if the pairing of the two components is complex enough. But the whole system, consisting of all the split pieces, the hardware transmitters and receivers, and the radio waves propagating between them, is not and does not have a soul. The identity of the person whose soul is split is lost forever; from their subjective viewpoint, it is equivalent to them dying. Best Regards, Richard B. R.
