There is a nuance that I think is important to discussions about free will, and this applies to Shapiro just as well as Saplosky: are we talking about fundamental free will (as per the fundamental rules of reality), or effective free will (something that's good enough in every practical sense).

I agree with Alex that there is no fundamental free will, in that regardless of whether you believe in a deterministic reality or a probabilistic one, there is simply a contradiction in terms between free (indicating something undetermined, unconstrained) and will (implying a level of control from the agent). If it's free, it's not will, and if it's will, it's not free. This would kinda require the agent to be external to nature to be both unconstrained and willful, and that's where we could plug God in to fill the gap.

But then Shapiro replies with "society does require an extraordinary number of people to believe that they are capable of making decisions". That's fine, there is really no contradiction here. We are able to make decisions. Those decisions are not free in the most metaphysical sense, but why would we want them to be? We are making decisions precisely to respond to the world around us.

It also doesn't matter that those decisions are determined by the world around us, and even that I am determined by the world around me, because that simply is what we are. All those determined causal chains still produce human beings that are conscious and (often) intelligent, and there simply is no alternative ideal ME that could exist independently of that. So inasfar as it makes sense at all to call myself a person, that person is one that is able to make decisions. In other words, the statements "I exist" and "I can choose" require the exact same assumptions. We do have effective free will.

The reason Ben thinks talking about "a series of chemical firings" is a good counterargument is that, I suspect, he has little scientific culture. One of the core ideas of physics is that complexity can emerge from simplicity through scale. A lot of simple chemical reactions can amount to something really complex and not reducible to the details of those reactions. Those two levels of description don't mesh.

By the way, I also think Saplosky is wrong when he says that since there is no fundamental free will, there cannot be any notion of responsibility. At the level of the fundamental, there isn't even a WE that could be responsible for anything. Choice, and responsibility, are notions that only exist at the level of an individual, so inasfar as the word responsibility even makes sense, we may have it. What we do with it is another matter entirely.

I think it’s worth mentioning that inserting God as a solution to the problem of free will is not as adequate as it’s being made out to be. Take for instance the verse in which Jesus predicts that Peter will betray him 3 times before the rooster crows. Jesus is said to be God, meaning he cannot be wrong. How exactly does Peter have free will? If he chooses to not betray Jesus that would make Jesus wrong and thus not omniscient. If Peter does betray Jesus that would mean his decision was already made up before he even realized what the decision was, thus relinquishing his free will. The theist may make the move of open theism but this brings along its own issues as well.
