| Oct 25, 2023 at 2:39 | comment | added | Andrew Bacon | FWIW I was wavering about asking the variant question about second-order arithmetic -- the more interesting question in retrospect. But I have accepted @spaceisdarkgreen 's answer as it is the correct answer to the question I actually asked. | |
