The Spacetime Locus of Consciousness BACKGROUND For cryonicists and immortalists, certain arcane areas of science and philosophy have intensely personal and practical significance. In particular, we want to survive--but the criteria of survival remain unknown. For example, there is no agreement on whether you "really" share identity with a duplicate or with a continuer or successor. Of course, most of us just blunder along and rely on intuition and "common sense." But intuition is notoriously fallible, and if "common sense" starts from the wrong premises then it isn't sense at all. Although most of our choices in life result just from guesses based on imperfect information, still we would like to clear away the haze as much as possible. As just one example of the relevance of these questions, Arthur C. Clarke is reported to reject cryonics because, to paraphrase his reported words, "Every ten years or so I am a different person anyway." To be sure, ostensible reasons for rejecting cryonics are seldom the real ones; nevertheless, we have to take this seriously. Let's look briefly, then, at some questions of existence in spacetime. My starting point is that the ground of being is in feeling, which constitutes or underlies the capacity for subjective experience, which is being or LAWKI (life-as-we-know-it). Thus feeling also underlies consciousness (which is the integration of feeling and computing), and distinguishes beings from robots. The physical basis of feeling I call the "self circuit" or the "subjective circuit"--although of course it may be distributed over segments of the brain (and over time!) and does not necessarily have much in common with an ordinary electric circuit. The one and only rock-bottom, physical/biological root of values is FEEL-GOOD. Apparently the only things that can ever matter to you--directly--are your own internal satisfactions or brain states. The only valid criterion of choice is maximization of your personal future satisfaction over time. Correct assessments and calculations are VERY difficult, because of the many apparent internal conflicts, among other things; but we are always concerned with the FUTURE, since the past and present are probably beyond our influence. WHY YOU ARE DISTRIBUTED OVER SPACE AND TIME Obvious requirements of being are that your consciousness have non-zero volume and non-zero duration. Spelling out the "obvious"--and for now leaving out of account the possible complications of quantum theory--we note: First, consciousness is a mechanism (or an aspect of a mechanism), and that a mechanism requires detail. Since (by definition) there can be no detail at a geometric point in space, you cannot exist at a point, hence must have non-zero volume. Consciousness is space-binding. Second, consciousness requires mental events, and an event requires duration. (Nothing can happen at a single instant of time, if there is such a thing.) Hence your existence requires non-zero duration. Consciousness is time-binding. In slightly less abstruse language, subjective experience depends on events in your brain, involving communication between different parts of the brain. Hence even the smallest experience must span space and time. To exist at all, you require a non-zero volume of spacetime. REMARKABLE IMPLICATIONS It seems fairly clear that, if we have extension in space and time, those extensions may be flexible, even manipulable. Presumably you (or an incarnation of you) survive, in the ordinary course of events, for at least about 1/20 second, which is roughly the limit of human discrimination between stimuli. But unless you have something very close to a simple film-frame existence, with no overlap between frames, it seems likely that you (or parts of aspects of you) have objective and subjective connections to somewhat more distant regions of spacetime. Quantum conjectures reinforce such notions. By extension and iteration, it seems to follow that YOU may exist, or partly exist, in rather remote times and places. By arguments too long to include here, it may even be possible that you share identity--in some sense and degree--with "other" people in different times and places, as various Oriental mystics have speculated or even insisted. Such results would be very strange indeed--but as Clarke and others have noted, the universe is not only stranger than we imagine, but probably stranger than we CAN imagine. If we give credence to some of these far-out possibilities, then I could be wrong in saying that nothing matters--directly--except what happens inside your own skull. But we must be very careful to distinguish between degrees of probability, and not treat all "possibilities" on an equal footing. BACK TO COMMON SENSE What is suggested by the above brief discussion is that--perhaps--most of us were right all along in our "inverse-square-law" attitude toward psychic investment. I.e., we regard as more important those potential events, and those people or objects or situations, that are closer in time and space, other things equal. But we must strenuously avoid any too simple-minded applications of this tenet. Too lazy an interpretation of this rule results in choice of short-term gratification over longer term and more global benefit. In terms of cryonics, nothing is new. We try to save both material and information as completely and reliably as possible. But the unknowns--while leaving open the possibility of inexorable doom in a user-unfriendly universe--also reinforce the possibilities for optimism, for hope in the face of the bleakest "reality." We just don't know enough to make hopelessness realistic in ANY situation. R.C.W. Ettinger Cryonics Institute Immortalist Society Rate This Message: http://www.cryonet.org/cgi-bin/rate.cgi?msg=6631
