X-Message-Number: 25320 From: Date: Tue, 14 Dec 2004 09:34:03 EST Subject: coadjunate minds Scott Badger added more discussion of split brains and possible implications. This is just a part of the general problem of coadjunate minds. When RBR talks about one mind or one QE per brain, perhaps he means this as an approximation or simplification, or possibly he just hasn't thought much about other possibilities. There are indeed other possibilities, although they do not necessarily invalidate RBR's main views. Brains are very complicated, one of the complications being that, as pretty clearly established, one brain can contain more than one persona or personality; also, elements within a persona can be at variance or even antagonistic. Lorenz spoke of the contentious "parliament of instincts" governing our actions and perhaps also our feelings. We don't yet know the anatomy/physiology of the self circuit or of qualia, or of their distribution in the landscape of the brain, or their hardiness or frailty, durability or transience. There is nothing in principle preventing a single skull from containing more than one "person," but we are probably justified in ascribing, as default, one (primary) person per skull. It's tricky, because a "person" viewed from the outside might be a label given just to a bundle of habits or responses, whereas the bundle of responses does not define you. It is even possible that, given blockages in the nervous system, your subjective life might have little to do with your external responses, conveying a very false impression to the laboratory observer. Further, there are suggestions in current theory, or current speculation, that there could be physical links between widely separated systems. Current theory also suggests that counterfactuals--things that don't or didn't happen--can have physical effects on things that do or will happen. All this together suggests a possible vague validity to the old Oriental notion of "sharing" selves among different people, that you live in me and I live in you. Someone else's subjective state could conceivably have a physical connection to yours. But of course any conclusions at all here would be grotesquely premature. The main thrust of recent postings has been survival criteria, and I don't think anyone suggests that it would make sense to place your main bet on duplication or uploading.
