@Zetherin,
This is all food for a separate thread, but it is an interesting issue, and I deal with it all the time.

Sure. You're not medically dead until there is cardiopulmonary arrest and no brain or brainstem activity. Brain death occurs when there still is cardiopulmonary function but the brain and brainstem are gone, but that is still technically alive.
Zetherin wrote:If he's alive and yet not conscious, there is still a code of ethics doctors have to follow that makes it illegal for them to pull the plug, right (unless there is consent from a family member)?
It's not as simple as pulling the plug, because there are people in "permanent vegetative states" who don't need much medical care other than nutritional support.
But you're not entirely correct about this. If someone is in a permanent vegetative state and they have NO family or guardian, then with the support of a hospital ethics committee and sometimes a court-appointed custodian you can institute comfort measures and stop things like life support, dialysis, and medications.
That said, we DO respect the autonomy of families, which means that we have to be very good about counseling them through these decisions. And it also means you get into the occasional ridiculous situation, which usually happens when families believe in miracles and don't realize that prolonging life without hope for recovery is torture.

A person is a "thing" whether they're alive or dead. But the issue is not their degree of "thingness".

No, we do it because the person in question has great meaning to their family, and it sometimes takes a long time to come to terms with death when medical care can postpone it.
I should add that most families are extremely reasonable about this, and it's much more common that they decide to do comfort care than it is to find an extreme case where people believe in miracles. Ironically, it's usually the relatives who live farthest away who push for full-on life support -- I think there's some guilt about not being close and some distance from seeing just what it's like to live like that.
