The question is, can a person with no higher order brain functions "want to live?" To want to live, you must understand the difference between life and death. In much the same way I cannot want to turn right without understanding that there is also the option to turn left. Otherwise right would simply be the only choice. If Ashley cannot understand that there is alive and there is dead, than she is just living. Just as I cannot want to go to heaven if there is no hell. If there was only heaven, then going to heaven would simply be a consequence of death.
You should be so overdramatic about what I have said. I simply said that people in these rest homes who are braindead are not going to recover. They have no visitors, and no prospects, and no comprehension of the world around them. Would it matter if I simply quit giving them their medications and let them die naturally? To whom would it matter? Is simply not giving someone medication, someone who does not desire the medication, murder?
Your post is obviously one from someone who's religious. When you start introducing religion into these arguments, then they become pointless. I cannot prove that the soul is simply a human construction given to ourselves in an attempt to seperate us from other living creatures and you cannot prove to me that the soul is something innate that humans are born with that gives us a sentience unique in the animal kingdom. Of course, if the girl did have a soul would she be better off here on Earth in her bodily prison or in heaven? Would God condemn Ashley's parents for removing the feeding tube? Hope, faith, belief are all things posessed by people. They stem from our higher order functions. Our imagination, conceptual abilities, sociological imagination, and human spirit all come from higher order functions. If Ashley doesn't have any higher order function (which may or may not be proven), how can she have these things?
I really don't think we can count on miracles. How many people die from cancer every year? How many in car accidents? How many families are ruined? How many people starve? How many people prayed for others? How many prayers were actually answered? I also believe in God, but that doesn't mean I presume that God wants this girl to survive. If she was supposed to be a functioning human, why hasn't He granted her a miracle yet?
