I wonder if Tom understands that in the way he didn't exist 4 billion years ago, he also didn't exist 4 picoseconds ago.
He didn't not exist. All of his existence was getting ready to be him then, same as it was getting ready to be him 4 picoseconds ago, and then it became the him of now.
I'm glad you mentioned this. It's important.
The value of a human individual is not their past. It's their potential in the future. All the stuff that individual might think, do, feel, whatever. It's all about human potential.
People draw arbitrary lines in human development. From implantation, to heartbeat, the brain activity, to birth. But those are all arbitrary divisions between the value of the human at the moment and the human potential of the individual. The potential of a healthy 20 something is more obvious, and actualizing their potential less of a burden on others. But it's the same basic thing, choosing death for one is destroying their potential not their history.
I appreciate your help explaining this.
Tom
