| Nov 26, 2022 at 22:43 | comment | added | Martín S | @NikWeaver Yes, that's my intuition as well. I guess the hope would be for some diagonal method to prove "I can prove that "This proof is a proof of C"", where "This proof" is specified as a quined object by some properties. | |
| Nov 25, 2022 at 17:29 | comment | added | Nik Weaver | I'm having trouble with the intuition behind this. The question is whether the intuitive template describes a valid proof. The only questionable step is (1), so we can say that it is a valid proof if and only if (1) is valid. That is, it is valid if and only if it is valid. I don't see how to go further than that. | |
