I like onions and mathematics and other things. I strongly believe that pure sets platonically exist, but that proper classes do not.

It's nice that Wittgenstein had the idea of Church Numerals before lambda calculus was even a thing (proposition 6.021 in the tractatus)

it would be so great to have transfinite lives...

ordinal turing machines (and equivalent models) are so cool, they can semi-decide the whether or not a Σ_1 statement of set theory is true, which has HUGE implications for phil of math but almost no one knows about them :-(

The symbol ∀ implies the existence of a domain being quantified over. So if you don't believe proper classes exist, you shouldn't believe that it is always meaningful for a Π_1 statement to be true.
