Thomas Donaldson asks why an archived tape would help a patient recover his identity, and whether someone else listening to your tape would become you [in part]. "Identity is not simply knowledge of facts." The brief answer is that information "read into" the brain of a patient, if it is correct, and in the correct biological form, and replaces missing information, then it certainly could help integrate and restore the patient's persona. It could not do the same for someone else, because it wouldn't fit. 2. Brook Norton tends to think "you" exist only in the moment (a bit like a single frame on a roll of movie film), but is nevertheless willing to live with this condition. That is a rare and brave position, and might even be correct. But I cannot emphasize too strongly that, in our current condition of ignorance, it is grotesquely premature to draw any firm conclusions about the nature of reality. Brook also questions my hypothesis that the "self circuit" is time binding as well as space binding. Let me see if I can clarify this a bit in a brief space. First, we know almost nothing about time, and have not resolved all the physical "paradoxes" of continuity, going back to antiquity. Whether space and time are continuous or quantized, mystery remains. In the Einsteinian view of spacetime, as usually interpreted, all of eternity coexists, or would coexist from the viewpoint of an entity able to visualize the whole thing. "Now," past and future are just subjective illusions. From the quantum viewpoint (sometimes seen as the film-frame notion) the situation is even worse, more garbled and contentious. However, from a common-sense perspective (which of course is often wrong), any "self circuit" necessarily binds both space and time. It binds space because it cannot involve only a single elementary particle; it requires a system spread over an appreciable region of space. It must also bind time in order to escape the "film frame" or quantum-chronon problem. It is hard to imagine feeling anything in a single moment, or having a single quantum state of your system represent an experience. Having qualia (probably) means feeling that something is happening, and (probably) nothing can happen in zero time or at a single chronon of time. In particular, a standing wave (with its modulations) must extend over both space and time. I have postulated something along the lines of a standing wave as the basis of the self circuit. 3. Mike Perry points out that your far-future self might still be interested in history, and especially in the history of you, of whom he is the remote continuer. That's true, and possibly comforting to some people, but not really relevant as far as I can see. Why should it matter to me, now, if in the far future someone else (whether or not my own continuer) will think about me? Others have said that, since "you" change over time anyway, a near-duplicate at the same time might be more "you" than your continuer at a later time. More similar, sure, but that doesn't really touch the basic problem, which is that we just don't have any sound or proven criterion (or set of criteria) to gauge "identity," nor do we even know how to state the question clearly. Mike Perry also says: >Sure, a measurement "proves" that you have two particles that are separate and >distinct. But in making that measurement, you have also put them in different >quantum states. When the states are the same, the behavior of the total system >is such that you have to treat them as identical. "have to"? Only for some purposes. (And even if the act of measurement changed the states, it did so separately to the separate particles, and they are still distinct from each other.) If I detect one alpha particle here, and another there, I certainly don't have to treat them the same way. Again, "state" is used in many ways, usually in a very limited sense and NOT taking into account ALL of the possible influences by and upon the system. 4. George Smith commented on the frequency of fabrications by those claiming remarkable memory disturbances or mental experiences, and Jan Coetzee reported one of his own experiences involving submerged personalities. Many strange stories are fabricated, consciously or unconsciously, but there are plenty of very strange yet apparently true stories. (Remember THE MAN WHO MISTOOK HIS WIFE FOR A HAT?) Once, as a young man, coming out of anaesthesia after surgery, I did in fact ask "What am I"-not "Where am I?" or "Who am I?" As a child on one occasion I had a waking hallucination, coming out of sleep. I could see the real room, with my parents present, but I could also see a lion coming through the window. And of course dreams bring countless fantasies, many of them unpleasant. Dream analysis may be a big thing some day. The bottom line, as usual, is that optimism is usually more productive than pessimism, and action is usually more productive than passivity. But we should resist the urge to pronounce unnecessary and premature conclusions--which is not the same as resisting the urge to speculate.
