ImprobableJoe said:You should have really read through the whole debate, because I addressed this aspect, although only fleetingly. The arrow of time only goes in one direction. It is meaningless to make absolute and specific claims of the future based on the past or present, because the potential paths of that arrow are infinite or close enough to it. The point is that there's a line from an embryo to an adult, but that line can only be traced once the adult exists. You can't start from the embryo and claim that you know anything about the potential adult at the end of the line, because that line only goes from the adult back into the past.
The "person-shaped hole in the world" is nonsense, because that person never actually existed. If I take an acorn and crush it before it can start becoming a tree, there is no "tree-shaped hole in the world." The confusion comes in mistaking hindsight for foresight. What we can see looking at what DID happen is nothing like what we can see looking forward at what MIGHT happen.
Oh, no, I quite understand. An observer that had my perspective would be something like a god, that observed from outside of our reality. Since such observation is impossible for humans, you don't agree that any speculation based on such an observer has any validity. The absence of a person who has been killed is no more meaningful then the absence of dragons or of an extinct species.
