Some religions assert that there is an eternal self. Other religions assert that the self is temporary but that something lives on.
My question is, what is it, philosophically speaking, that links one moment of consciousness to another moment of consciousness that allows it to be considered the same being?
Thought Experiment One:
The movie, "The 6th Day", with Arnold Schwarzenegger (spoilers ahead, but it's a ten year old movie), is about cloning. In this future, technology exists to not only clone humans, but to accelerate their growth. In addition, memories can be captured and placed into a clone.
Arnold comes home one day to find that a clone of himself is inside with his wife and kids. He goes on an action-packed quest to get to the bottom of this. In the end, it turns out that he was the clone, not the other one that was in his house that night. He had the body and memories of the original, so he thought he was the original. He incorrectly assumed he had a continuous consciousness when in reality, he's a very young being that simply has memories of another implanted into him. (In the movie, clones are purposely given a mark so that they can be identified. That's how he finds out he's the clone.)
Suppose that while sleeping, you are killed and replaced with a clone with your memories. This clone would wake up and never knew anything happened. The original would be dead, but the second one would mistakenly assume that it has had a continuous consciousness when in fact it's a new being.
What makes our bodies continuous? I've read that most of our cells are replaced every few years. Some studies have said that there are areas in the brain where the cells last our entire life. If cells are replaced in small amounts over time, and eventually the entirety is replaced (even those brain cells), is consciousness continuous or no? How would we know?
Thought Experiment Two:
So far, science seems to have revealed that consciousness is an emergent property of the brain, either in total or in part. For instance, damage to the brain can drastically alter one's personality or render the person unable to be conscious anymore, either temporarily or permanently.
So suppose that you die. You wake up in an afterlife. Is this person that wakes up still you? Is it a copy, or is it a continuous consciousness of the original? How can it be determined? If it's merely a copy, then to the original person, they have no afterlife. The copy experiences the afterlife, but not the original.
Thought Experiment Three:
I've seen some proponents of reincarnation say that when one dies, they are reincarnated in a new form. The new form probably won't have your memories, might be another gender and born in a totally different culture, and may or may not have remnants of your personality (people I talk to have had different notions about this last part). What makes this reincarnated version still "you", rather than a wholly separate being?
