Prove it - roll back time and see if I make a different choice. You'd probably need to repeat the experiment a number of times to get a statistically significant result.
Or explain to me what physical forces constrain me to only ever choose the sword.
That's the problem, we can't run the experiment more than once. But at the time you might have seen a sword in a window somewhere, or watched the pawnshop scene in Pulp Fiction, or whatever.. Those are some external influences.. On the firing of neurons to randomly choose A or B, those nurons are chemical reactions which are pre determined by chemistry, the chemicals react to chose A for whatever reason, it would be breaking the laws of physics for them to choose B..
This is still you making the call, but on close inspection, there is no 'Free will'..
He is saying that my choice is not "free" because a choice was already made at some neural level before I made a consciously choice. But he is assuming that that neural level isn't part of my intellect. That some other level of which I'm not aware is pre-selecting my choices for me so my choices are constrained.
He is saying the choice is not 'free' because it picked X at the neural level, for whatever reason... The point is X was chosen, Y was not, and under that scenario X was always going to be chosen..
I think the notion that these things are done without our awareness is a bit specious. That neural level that is making the choice certainly isn't part of anyone else's consciousness! It's still part of me. I still make the choice.
You do make the choice, but you don't have a choice in what choice you make.. You will choose X and there is nothing you can do about it,
"ahh, so I will choose Y, just to spite X"
"But, weren't you always going to choose Y, to spite X?"
