You see the reason I posited the question is that I'm trying to figure out what the metaphysics behind the belief in uploading is. The first point you raise, regarding a 1-to-1 mapping, makes me think: what is it precisely that we are trying to map? Is it the physical nature of the body as it is at one particular point in time? Or is it the physical state of the brain at one point in time? Because I think the idea that the two sources I quoted are getting at, is that there is a whole lot more to selfhood (and consciousness) than that. The self being a very fluid, loosely tied bag of stuff, we have inevitably to reduce it to some clear-cut definition in order to be able to 'map' it at all. If we accept that I now am not the same
person I was seven years ago, then what exactly is it that we are trying to preserve via uploading? It cannot surely be a continuation of "my" consciousness if we accept the two can exist side by side. So, is it simply our pattern of behaviour?<br><br>Secondly, how can we claim to know with precision the physical state (which is by definition a temporal process, not a static state) in order to map it '1-to-1'? Is the idea that we simulate the physical processes so that we are sure the virtual-brain behaves in precisely the same way a physical one would (ie, processing information in exactly the same way; dealing with sensory input in exactly the way a biological brain does)? How is this possible before we know how consciousness occurs as an epiphenomenon of physical processes?<br><br><div style="font-family: times new roman,new york,times,serif; font-size: 12pt;">----- Original Message ----<br>From: Damien Broderick <thespike@satx.rr.com><br>To:
