If any of you are familiar with Frank Herbert's Dune series (if not i highly recommend reading at least the first book), you may be aware of an interesting concept that is raised within the books: the ghola. A ghola is essentially a reanimated corpse of sorts, where the dead individual's body is reformed using the tissue/DNA from their body, either by physically recreating the body in its state before death (not the most realistic of the two ways to create a ghola), or by creating a clone of the dead individual. For the sake of this post i would like to focus on the second option (the clone), as it is much more realistic. In the books, (which, if you haven't figured it out already, are science fiction) the memories, personality, etc., of the deceased person are reawakened, and for the reawakened individual it is as if they were brought back from the dead. While this situation is obviously not at all realistic, it does bring up some interesting questions like: 1. If such a thing were possible, would the resulting person be "you"?, 2. What constitutes "you"? Is it your memories? Your personallity? Your flesh and dna? Or some combination of all of them?, And 3. In situations where you "die" briefly (certain essential area's of your body shut down and or your brain is no longer fully functional) and are brought back via adrenaline injections, defribulation, etc., why is this different from the "ghola" you? Because typing out a long long post that goes into the details of my thought process on this was rather impractical, i had to simplify things a bit, but i hope you get the gist of what I am saying. And please, don't hesitate to take things further than i do in the post or to criticize.
