    > But if we have no agency, nothing matters. There can be no morality: a criminal was always destined to commit a crime. It was never right for us to punish them, but that’s okay: we couldn’t have acted differently, so we shoulder no blame.

    Right, and determinism seems likely to me to be correct, but I don't see the issue. Whether we'd like things to matter has no impact on whether they really do, but the obvious conclusion along the same lines that "saves" us is that you should act as if you believe in free will (e.g. enacting punishments) even if you don't. Either there is free will, so you behaved correctly, or there isn't, so you didn't really decide how to act anyway.

      Why does it matter how you "should" act if there is no free will. You are just going to act how your are going to act.

        Right, this is why you resolve act as if there is. If there isn't, then "you" didn't really resolve to do anything anyway, or at least it was inevitable that you would make that choice (for example that you would follow this line of reasoning) so it didn't matter. "You" weren't wrong because "you" weren't anything but an automaton.

        If there really were such a thing as free will, whatever that means, then by acting like there is, you were acting correctly.

        It's sort of like how in math, when you're dealing with an if statement, a false premise gives your conclusion for free. You only need to consider the case that you have a choice in the first place when deciding how you should act. Therefore you should act as if free will exists, even if deep down you really don't believe it does.

        Basically "I should choose to act as if I have free will" really expands to "if I can choose how to act, then I should choose to act as if I have free will," which is then straightforward basic logic.
