Which is indeed the main task to do for a non-mechanist. Now, that might not be entirely true. Gödel did try to get a notion of non computable finite object, and recently I find a way to build a model of ZF(or even PA) in which such finite object are not computable, but those models are highly non standard, and such finite things are “truly” infinite, so I don’t believe Gödel’s idea could succeed, nor that he ever took this seriously, as other writing of him put doubt on this. So I agree with you, a non mechanist must conceive actual infinite brain capable of doing an infinity of task in a finite time. Only that can make him hoping to escape the UD statistics in arithmetic.
