From my “watched a YouTube video” understanding of Gödel’s Incompleteness Theorem, a consistent mathematical system cannot prove its own consistency, and any seemingly consistent system could always have a fatal contradiction that invalidates the whole system, and the only way to know would be to find the contradiction.
So if at some point our current system of math gets proven inconsistent, what happens next? Can we tweak just the inconsistent part and have everything else still be valid or would we be forced to rebuild all of math from basic logic?
ah I gotcha, thats fair then.
On another note, you’d propose a von Neumann hierarchy without AoC? How would that class be defined?
Admittedly I’m not that big into class theory so I am likely missing something obvious, but to me it seems like the definition of the class requires such a selecting function
