I accept the bullet biting response. I think someone who doesn’t should say the utility of the observers may outweigh Jones’ utility but that you should save Jones for some deontic reason (which is what Scanlon says), or maybe that many small bits of utility spread across people don’t sum in a straightforward way, and so can’t add up to outweigh Jones’ suffering (I think this is incorrect, but that something like it is probably what’s actually driving the intuition). I think the infinite disutility response is wrong, but that someone who accepts it should probably adopt some view in infinite ethics according to which two people suffering infinite disutility is worse than one—adopting some such view may be needed to avoid other problems anyway.
The solution you propose is interesting, but I don’t think I find it plausible:
1. If Jones’ disutility is finite, presumably there is some sufficiently large number of spectators, X, such that their aggregate utility would outweigh his disutility. Why think that, in fact, the physically possible number of observers is lower than X?
2. Suppose Jones isn’t suffering the worst torment possible, but merely “extremely painful” shocks, as in Scanlon’s example. So the number of observers needed to outweigh his suffering is not X, but the lower number Y. I suppose the intuitive answer is still that you should save him. But why think the physically possible number of observers is below Y?
3. Even if, in fact, the physically possible number of observers is lower than X, presumably the fundamental moral rules should work across possible worlds. And anyway, that seems to be baked into the thought experiment, as there is in fact no Galactic Cup. But even if the physically possible number of observers is in fact lower than X, it could be higher than X in another possible world.
4. Even if the possible number of observers is in fact finite, presumably there are possible worlds with an infinite number of possible observers (the laws of physics are very different, or time is infinite into the future, or there are disembodied ghosts watching, etc.). If we think the solution should work across possible worlds, the fact that there can only be a finite number of observers in our world is then irrelevant.
5. You assume our lightcone is finite “with certainty.” I assume this is because of the expected utility concern if there is some chance that it turns out not to be finite. But I think you shouldn’t have epistemic certainty that there can only be a finite number of observers.
6. The solution seems to get the intuitive answer for a counterintuitive reason. People find letting Jones get shocked in the transmitter case counterintuitive because they think there is something off about weighing one really bad harm against all these really small benefits, not because of anything having to do with whether there can only be a finite number of observers, and especially not because of anything having that could depend on the specific number of possible observers. Once we grant that the reason for the intuition is off, I’m not sure why we should trust the intuition itself.
*I think your answer to 1-3 may be that there is no set-in-stone number of observers needed to outweigh Jones’ suffering: we just pick some arbitrarily large amount and assign it to Jones, such that it’s higher than the total utility possessed by however many observers there might happen to be. I am a realist about utility in such a way that we can’t do this. But anyway, here is a potential argument against this:
Forget about what number we arbitrarily assign to represent Jones’ suffering. Two people each suffering very slightly less than Jones is worse than Jones’ suffering. Four people each suffering very slightly worse than them is worse than their suffering. Etc. If we keep going, we will reach some number of people undergoing some trivial amount of suffering which, intuitively, can be outweighed by enough people watching the Galactic Cup—call that number of observers Z. The suffering of those trivially suffering people is worse than the suffering of Jones, by transitivity. So the enjoyment of Z observers outweighs the suffering of Jones, by transitivity. And there is no reason to think the actual number of possible observers is smaller than Z.
Thanks for such an in depth reply! I have two takes on your points but before that I want to give the disclaimer that I’m a mathematician, not a philosopher by training.
First, we’re not saying that the lightcone solution implies we should always save Jones. Indeed, there could still be a large enough number of viewers. What we are saying is this: previously, you could say that for any suffering S Jones is experiencing, there is some number of viewers X whose mild annoyance A would in aggregate be greater than S. What’s new here is the upper bound to X, so A*X > S could still be true (and we let Jones suffer), but it can’t necessarily be made true for any Y by picking a sufficiently large X.
As to your point about there being different number of viewers X in different worlds, yep I buy that! I even think it’s morally intuitive that if more suffering A*X is caused by saving Jones then we have less reason to do so. This for me isn’t a case of moral rules not holding across worlds because the situations are different, but we’re still making the same comparison (A*X vs Y). I’ll caveat this by saying that I’ve never thought too hard about moral consistency across worlds.
