What concrete scenario would be possible if you had free will, but would be impossible if you were a material being in a deterministic universe?
Would you mind framing this question in an example?
This might not be the best scenario to illustrate the difference between free will and determinism, because I don't believe there is a difference. But it's the best example I can find of the kind of scenario I have in mind for someone else to propose.
Let the entire state of the universe at one moment be such that that in the next moment my lips will say, "Yes." That's what the nerve impulses, the electrons, the photons are heading to do, so that's what will happen under the laws of nature. Under the deterministic laws of nature it will be impossible for me to say, "No." But (I'm proposing that someone else might say) in the case where I have free will, I can somehow nonetheless say, "No" instead of, "Yes."
That's the closest I can come to an example of the kind of concrete scenario that I'd like to see offered. If someone offered this scenario as an answer to my question, I would then ask, "In the case where all the particles are heading for 'Yes' but you have free will, what would make the difference between you saying, 'Yes' and you saying, 'No'?"
I would expect an answer like, "My intention would make the difference. If I want to say, 'No,' and I have free will, the laws of nature will just have to bend and let my lips utter, 'No.'"
I would then ask for agreement, expecting it to be granted, that even if you have free will, you will still never say, 'No' when all the particles are heading for 'Yes,' if you also want to say, 'Yes'.
I will then interpret this as an admission that if you have free will then your intention is still just another deterministic causal factor along with all the neurons and electrons. If all of the causal factors, including your intention, are heading for "Yes," then you will always say, "Yes." Only if at least one causal factor were different—namely, your intention—might you instead utter, "No."
My conclusion will be that free will is still completely deterministic.
