I was just wondering about the JW concept of lifeforce v. spirit.
Now I'm a big fan of Stargate SG-1/Atlantis and, to a lesser degree, Star Trek. And the question I always had about the whole dematerialization and rematerialization process used in wormhole travel and beaming and such is this: If I understand it correctly, ever time you dematerialize, you're effectively killed, or cease to exist. The version of "you" that steps onto the transporter or jumps into the wormhole gets completely zapped and the one that reappears on the other side is simply a perfect copy, with all the memories, feelings and so forth. And that version would be completely unaware that he or she (in the case of the very attractive Amanda Tapping) is not the original, but, as I said, a perfect copy.
If I were a JW, I'd be concerned that the version of me that was dying might be the "original" and that the one resurrected would be just a lifeforce "copy." It would look, think, act and recall just like me, but would it actually be me? In other words, I can copy a Word file on my computer to a key disk, and it would open and act just like the original (the one that was erased). All the fonts, colors and sizes would be right, right down to the slightest detail, but the original would be on my hard disk and, most likely, overwritten. All the 00s and 01s would be identical down to the last detail, but it wouldn't be the same.
Dr. McCoy may have been right. If he stepped up onto the transporter, he would be completely dematerialized, beamed a considerable distance, and then the computer (hopefully) would put all the parts back together again. I thought of this again when I watched a Stargate episode where SG1 was knocked unconscious on a strange planet (they're always strange, right?) When they came to, they were dressed differently, managed to find their weapons and gear and escape. But back at Stargate Command, they soon began to weaken and pass out. It was soon discovered that they were not, in fact, SG1 at all, but replicas in robotic bodies. At first they wondered how their consciouses had been transferred, but they later learned that their minds had not been transferred at all, but that they had been replicated. Moreover, the original team members had revived and they wanted their lives back! Each had identical memories, feelings -- everything -- but despite the fact that they were self aware, they were merely copies.
The show raised some fascinating ethical points, and now some theological ones as well.
What do you think?
