So what? What thought experiment does this lead to that causes a challenge for ethics? If infinite undefined-ness causes a problem for ethics please specify it, but so far the infinite ethics thought experiments I have seen either:
Are trivially the same as non-infinite thought experiments. For example undefined-ness is a problem for utilitarianism even without infinity. For example think of the Pascal’s mugger who offers to create “an undefined and unspecified but very large amount of utility, so large as to make TREE(3) appear small”
Make no sense. They require assuming two things that physics says are not true – let us assume that we know with 100% certainty that the universe is infinite and let us assume that we can treat those infinites as anything other than limits in a finite series. This make no more sense than though experiments about what if time travel was true make sense and are little better than what if “consciousness is actually cheesy-bread”.
Maybe I am missing something and there are for example some really good solutions to Pascal’s mugging that don’t work in the infinite case but work in the very large but undefined cases or some other kind of thought experiment I have not seen yet in which case I am happy to retract my skepticism.
