like you can take a look at the wacky stuff here, it's not hard to e.g. describe ordinals so large ZFC can't construct them, or any other particular computable list of axioms for set theory!

*how weird definite-but-not-surveyable collections are

like the collection of countable ordinals is truly insanely large, almost all of them are impossible to describe in any fixed ordinal notation, e.g. almost all of them are uncomputable. it's extremely different in character from N

i haven't thought through this carefully but yeah, i think in this framework aleph_1, or more precisely omega_1 thought of as the collection of all countable ordinals, is definite but not surveyable. in other papers i think he does a good job emphasizing how weird surveyable collections are

every picture or video of an animal is pretty much universally good, like it's really hard to go wrong with those. the fact that the same isn't true of humans points at some things that i think are very sad

the version i heard as a kid was about russian to english and it ended up "the vodka is strong but the meat is rotten," this was a strong meme back in the day
