I apologize, and I admit it may be of relative importance as stated above. Most important, I think, there is an objective definition of self-hood - we just may not know for certain what it is. There are many things (as you may know better than I) that we don't know for certain, but if one is an Immortalist it may be critical for one's survival to know the answer to this one. What I am not as confident on is the role of individual values in the arena of survival. Wouldn't it seem like an objective definition is often more important to one's survival than individual values? What if they are opposites? Searching for that objective definition now is critical because someday there may be options available like: 1. Uploading; 2. Sownloading; 3. Changing brains - in with the new, out with the old; 4. Reanimation from cryonics by repairing the old brain versus taking the old brain apart one atom at a time and making a new brain with atoms in similar positions; 5. Making duplicates, and then destroying the original; 6. And, other options that we have not even thought of yet. If you choose the wrong option and it objectivly ends your survival, and you are really dead, and then new guy (with your old memories) thinks he is you, and no one else realizes that a critical mistake has been made (they also think the new guy is you - he is acting just like you used to - how could they have known?), then the mistake may be repeated often. Medical reanimators in the future may think they are restoring frozen patients when instead (because they are using the wrong techniques) they are insuring the patients will be dead forever by destroying the very thing that made you you and me me. ..................................................... Why it does not seem like the essential element is memories. I admit that memories may play a supportive role in overall self-hood, but memories change over one's life - they can be so fleeting. I don't have all the memories that I had yesterday. I don't have all the memories I had a year ago, or 50 years ago. Tomorrow I will have some different memories that I never had before, but over all this time I am still me - an always changing being (a continuing process of self-awareness). What I am looking for as a marker is a thing about selfhood that doesn't ever change, what thing remains constant, what is that thing that we can identify that makes us us?? In any brain: 1. Memories change. (explained above) 2. Atoms change. (known) 3. Structure changes. (Dendrites and dendritic spines are constantly changing, and synapses change) What doesn't change? The *continuing process* itself of feeling different memories and self-awareness doesn't change: The Unique-Self-Aware-Continuing-Process. Let's look at it another way: If we admit a Cartesian starting point (that at least we know we exist because we can doubt that we exist and we could not do that if we did not exist), then I would submit that we also have to be self-aware to hold that doubt. If I were not self-aware (aware of my self thinking doubts and other thoughts) I would NOT know that is was myself that was doing the doubting. If I do not know it is my self that is doubting than I do not know that I exist and we lose even the slim Descarte's tidbit of true knowledge - we then would have nothing. However, we can go beyond Descarte: I doubt therefore I am. (How do I know I doubt?) I am aware of my self doubting. Therefore it is the self being aware of itself doubting (aka: self-awareness) that makes me me. Dave Pizer Rate This Message: http://www.cryonet.org/cgi-bin/rate.cgi?msg=14221
