newnumber6: Ghostly being (Default)
Just a little thought experiment.

Premise 1: Multiple Universes exist from every possibility. This is like you see in SF shows all the time - for every choice (either personal or right down to particle interactions), the universe branches out into two (or more) possibilities, creating a new timeline for every possible choice.

Premise 2: Identity (for people) is a combination of two one-way operators (was and will be) which are continuous from any moment X to and moment Y in the future for will be, or past for was, where the state of the object in the earlier (or later) moment is directly dependant on the earlier moment. That is, I was me at 5 if the state of me now is a result of a continuous set of changes from me at 5 until now, in my universe. I will be me at +5years if the state of the character 5 years from now in any one universe is a result of a continuous set of changes over 5 years in that particular universe. This allows there to 'will be' multiple mes at +5 years, but they cannot claim to have identity to each other, because although they share a was connection, they don't share a will be .

Premise 3: There is no afterlife of a supernatural nature.

Under premise 2, it is theoretically possible that there is a non-supernatural afterlife (after death, some advanced entity is able to look back in time to the moment of death and register the mental states, and recreate it), but we will not consider it at first to simplify matters.

Premise 4: Life is awareness
That is, you have to have some level of present or future awareness of your condition to be considered alive. If you've been braindead and in a coma with no awareness for 30 years and then die, technically, for the purposes of the argument, you've been dead 30 years. If you're in a coma with no awareness for 30 years, wake up, and die 5 minutes later, you were alive the whole time. What counts as a level of awareness we can leave somewhat vague. It may well include reduce mental states, dreamlike comas, or extreme brain damage that leaves you functional, or it may exclude those after a point. It doesn't strictly matter which one you choose, so long as you're consistent about it. (Where necessary, we will use 'technical survival' or 'technical life' to talk about moments where the body is alive but there is no awareness)

Arguement: Take a suicidal person. Let's call him Gil Read more... )
