It seems the whole debate boils down to two things:
1. Whether a digitised personality is a 'real' personality.
I happen to think not since DNA and memories are physical things linked to our bodies - a personality loaded into a robot body or a holodeck program is NOT thinking in the same way as a biological entity (or at least not in the same way as a human) unless their entire brain and DNA is also duplicated in the same (albeit artificial) form (i.e. closest I can think of is Ilia). I think they just APPEAR to be the same person because they are programmed that way. To me, the EMH should not have been protrayed as a person i.e. human, but rather a simulation of a person in the same was as Ash and Bishop in Aliens think quite differently to the humans despite having a superficial similarity. He would have been FAR more exciting if he had been a bit off - like the replicants in Blade Runner (but less psychotic). Trek's allegorical roots really let them down when portraying societies and psychologies that think differently from how their audeince thinks (V'Ger being a notable exception).
Pauln6:
See, but that's just the thing. How do you know that the transporter process just doesn't flawlessly turn you into energy and restores you back to original state without killing you? Just because you de-materialize and then re-materialize doesn't mean you die and get copied.
In other words: the transporter actually works like this....
1. Your physical body de-materializes.
2. Your soul (i.e. mind) and spirit body travel along for the journey because you are not technically dead because you are changed into energy during the de-materialization and re-materialization process.
3. You get converted into energy for transport with your mind attached.
4. Sometimes you are able to perceive that you can move a bit inside the matter stream even though your physical body doesn't move from the point it entered and to the point it returned (Again: this is probably your spirit body or a mental image of yourself in the energy state you are living in).
5. Your mind is retained in the energy conversion process (which suggests you really are not dead).
6. Your physical body re-materializes back and is indistinguishable on a genetic level from the physical body that stepped onto the transporter pad.
In other words there is no evidence to suggest that the body is in fact killed. It is simply converted into energy (with the mind attached) and then converted back to it's original form.
I mean, it is sort of like someone flashing out of phase for a second and then coming back. However, just because the body is deconstructed and then put back together flawlessly during this process does not mean in no way that it is still not the original person. The body simply could have been out of phase and the body could be perfectly put on hold or stored in an energy type state.
However, if you are still doubtful: there is another piece of evidence that suggests that the transporter is more a car ride (or a transference) than it is a copy machine. In DS9's "Field of Fire": O'Brien attaches a micro-transporter to the muzzle of a TR-116 rifle and beams a bullet in order to hit a target through a wall. When the bullet re-materializes and hits it's intended target, it ended up having the same kinetic energy as it had when it was first de-materialized.
I mean, how does the transporter destroy, digitize, and then replicate kinetic energy? The simple answer is that it doesn't.
The bullet simply gets phased into energy and continues to travel along in an energy like state (within a second or two) and then it re-materializes on the other side with that same kinetic energy.
If digitised personalities still count as the real person then the transporter is not producing a copy but is re-integrating the person back into the copied body.
If the transporters were to exist for real, perhaps this is how it would have worked. But in Star Trek, we are given evidence that the transporter doesn't operate this way. It presents to us an impossible thing that bends the laws of normal science. We either accept what the series tells us about this fictional device or we reject it. It is that simple.
2. Whether humans have a soul that is quite separate from their physical being and that is capable of being sent to the transporter site at the other end to 'jump' back into the reformed body.
Of course if Trek folk all have a soul then God must spontaneously award them to clones and copies like Tom Riker as well if we want to treat them as 'real' people and possibly sentient artificial beings? This is a bit wibbly wobbly for me. I'm willing to entertain the notion that some part of us can float off to another dimension when we die, I'm less enamoured with the notion that they enjoy transporter trips.
Not if your body doesn't really die and you are flawlessly phased and re-phased (i.e. de-materialized and re-materialized) during the transporter process. But let's say for example that the body did die during the process: do you really think your soul would leave your body that quickly (especially when there is higher power out there that knows what it is going on)?
As for Tom Riker being an approved new identical twin (or an original) that has come into the world: Well, there are all kinds of life out there that is not the standard norm in todays day and age. Just because the creation of this life form came about differently doesn't make it any less likely that it could have existed.
However, if we assume that our souls are not quite so individual and are not linked directly to our bodies but rather that God is using them as a focal point to peek into this universe then that's ok, the omniscient God can re-establish the link with the reformed body and the 'real' person is preserved.
From the Bible, or other doctrines, and from near death experiences, we learn that there is a spirit world (i.e. unseen dimension) that co-exists within our physical world.
Also, God doesn't need to peek into our universe through a person in order to see what it is going on. He can clearly see both the physical world and the spirit world because He is God (The maker of the Heavens and the Earth).
