it's his choice, it's HIM. Right?
Yep.
You can move forward, if you like.
So, the rest of the thought experiment is really just ruminating on what's already been said. There's no new scenarios, but there is I think plenty to talk about in what's already been said.
Goes 1-4 he chooses teet. Go 5 he chooses to cry. The source of that difference? The source of the difference between 1-4 and #5? The source is, according to the libertiarian free-willist, HIM.
We'll call him Willy, if you will. Free Will Willy. His name now is William Sasso - he goes by Free Will "Free Will" Sasso now. But that's all beside the point.
Willy is the source of the difference.
But, we've established that when we rewind time, Willy is the same. When we rewind back to moment -1, Willy is in exactly the same state every time - we've perfectly rewound every aspect of him. So... can he really be the source of the DIFFERENCE if he's the SAME? (forgive me for typing like Age here, but this is important). I find it... unsatisfying, to say the least, to say that the source of the difference is something that was the same.
Let's consider a completely different example of something entirely unrelated to see perhaps why it's so unsatisfying. I've got two examples, one neat and one messy.
Example 1: the neat example -- We work in a physics lab. We have a supercomputer that does relativistic calculations of physical scenarios. We've prepared a simulation - we're going to roll a rock down a hill. Now, our simulations software is perfectly deterministic -- OR SO WE THINK! So, we roll the rock down the hill, and it bounces down and hits various rocks and dirt clumps and pieces of grass, and near the bottom of the hill it bounces off this one particular other rock and it bounces right-ward.
And then we reset the simulation -- the simulation that we've apparently programmed to be deterministic -- and something unexpected happens. For some reason, the rock bounces left.
So I look to you and I ask you, "Why did it bounce left this time?" And your answer to me is, "Because the rock model was a perfect sphere."
And so I ask you if it was a perfect sphere on the run where it bounced right, and you say "Yeah of course". And I say "so why did it bounce right?" and you say "because it was a perfect sphere."
Now, at this point, me and everyone else in the room is looking at you like... WHAT? It was a perfect sphere, perfectly the same both times we ran the simulation, and you're saying that THAT'S the source of the difference? The source of the difference is something that was perfectly the same between them? Does that make sense? I certainly can't make sense of it. I want to find a difference to explain the difference, intuitively, I don't want to look at something that was perfectly the same to explain the difference.
Example 2: a little bit more messy -- We observe two children playing in a playground. They're very similar, both rich, white, from rich white christian families, family intact with a rich white mom and dad. I say to you, "hm, I wonder how their lives will play out". Fast forward many years. One of the kids is a multi-millionaire, successful, running a business of his own creation. The other one is in a half way house for drug addicts.
"How did their lives turn out so differently?" I ask you. "Well, you see, this one had rich white christian parents", you say. I give you a funny look. It doesn't make sense to me. As an explanation for the source of the difference, it just doesn't make sense to me. You've pointed to something the same between them as the source of the difference...
This is where I get hung up with libertarian free will. This is where I go from thinking "I don't know if libertarian free will exists, but I'd like to see some evidence" to thinking "I don't know that there's ANY possible state of the world that could possibly correspond to free will existing. I think it's just untenable".
The idea that you could explain the source of a change between two scenarios as being something that was perfectly the same between the two scenarios just seems intuitively extremely absurd to me, and I believe most people would understand my intuitive reaction here. Do you understand why it feels intuitively absurd to me?
