Anyway, you wrote the following: >>Processes have no properties at all,because they are concepts and not factually existing things.>> >>Therefore, software can never be considered alive or conscious. Consciousness is a property of hardware---a system has it or does not, and the type of consciousness it has no doubt depends on the specifics of the hardware.>> Isn't installing a software program on my hard drive simply a particular arranging or patterning of the atoms that compose the hard drive? If so, then software is simply patterned hardware. Much like in the brain. I don't understand your statement that processes "are concepts and not factually existing things". Well, you're right that process is not a 'thing', but it's certainly more than an abstract concept. A change in state "is" process. It's not a thing, it's an action. Experience is what happens when the brain system is processing a sufficient amount of data. Consciousness is action. You are a process. The mind is what the brain does, not what the brain is. The rather unique manner in which your system processes data is what I believe you wish to preserve. But I'm doubtful that there is a particular location in the brain whose processes are responsible for the soul you refer to. I'm personally not convinced that your objections to competing theories are, as you say, "insurmountable". The nature of consciousness and the strong sense of self and conscious will that we feel are hotly debated topics. I recommend to those interested Susan Blackmore's article below for some further overview. I've included some relevant snippets. Please note the last paragraph which addresses the competing "ego" vs. "bundle" theories of consciousness. Libet's Experiment on Voluntary action and the sense of free will http://www.susanblackmore.co.uk/Articles/psych01.htm Hold your arm out in front of you and then, whenever you feel like it - of your own free will - flex your wrist. Do it several times and watch what happens in your own mind. You may feel as though you first consciously decided to move, and then moved. It feels as though the conscious decision caused the action. Trying it for yourself helps with thinking about Libet s famous experiment on voluntary action (Libet 1985). Libet asked people to do just this, while he systematically measured the timing of three things. 1. The start of the action - using electrodes on the wrist. 2. The start of the readiness potential in motor cortex - using electrodes on the scalp. 3. The decision to move - using a revolving spot on a clock face (subjects had to say where the spot was when they consciously decided to act). The last of these was the most controversial but subsidiary experiments showed that people are able accurately to time external stimuli this way. The assumption is that they could do the same with their own private decisions. So - which came first? The decision to move, or activity in motor cortex? The answer was more dramatic than anyone expected. The brain activity began about 500 milliseconds, or half a second, before the person was aware of deciding to act. It seems that the conscious decision came far too late to be the cause of the action; as though consciousness is a mere afterthought. Odd though this might seem, it fits with previous experiments on exposed brains, in which Libet demonstrated that about half a second of continuous activity in sensory cortex is needed for a person to become aware of a sensory stimulus (Libet 1981). This implies the odd conclusion that consciousness lags behind the events of the world. But, Libet argued, once events reach neuronal adequacy (i.e. half a second of activity) they are subjectively referred back to the time of the initial evoked potential. So even though consciousness takes half a second to build up, events still seem to happen in real time. Wegner argues that free will is an illusion created in three steps. First we are ignorant about how our brains plan actions and carry them out. Second, we become aware of the results of the planning and call these intentions. Finally the action occurs after the intention and so we leap - erroneously - to the conclusion that our intention caused the action. Not everyone agrees with this interpretation, and there is currently vigorous debate about how neuroscience can contribute to our understanding of free will (Libet, Freeman and Sutherland 1999). Nevertheless, these results should make us question any conclusions we base on our undoubted feelings of conscious control. Just how deep is this illusion then? Dennett (1991) suggests that the fundamental error is to believe in what he calls the Cartesian Theatre . Theatre metaphors are common in discussions of consciousness, and arguably can be helpful (Baars 1997). It certainly feels as though I am sitting inside my head and experiencing the events in turn as though they were some kind of show. But this is a big mistake, argues Dennett. While almost everyone rejects outright Cartesian dualism, most psychologists and neuroscientists still believe in some kind of centre, where everything comes together and consciousness happens ; some kind of magic finishing line beyond which events come into consciousness, or a centre from where my decisions are made and my instructions sent out. But this cannot be, for the reality of the brain is a massively parallel system with no middle. So, as Dennett puts it When you discard Cartesian dualism, you really must discard the show that would have gone on in the Cartesian Theater, and the audience as well, for neither the show nor the audience is to be found in the brain, and the brain is the only real place there is to look for them. (Dennett 1991, p 134). Is there really no persistent me who lives this life; who is conscious and who has free will? Consideration of the nature of self is deeply bound up with questions about consciousness, as recent debates reveal (Gallagher and Shear 1999). Philosopher Derek Parfit (1987) divides theories of the self into two types - ego and bundle theories. Ego theorists (perhaps the natural way to think) believe in a persistent self who is the subject of experiences and whose existence explains the sense of unity and continuity of experience. Bundle theorists (named after Hume s (1739) bundle of sensations ), deny there is any such thing. The apparent unity is just a collection of ever-changing experiences tied together by such relationships as a physical body and memory. While ego theories come easily to most of us, intellectually some kind of bundle theory seems ever more inescapable. Cheers, Scott Rate This Message: http://www.cryonet.org/cgi-bin/rate.cgi?msg=25175
