    “If your method requires infinite storage space and computation speed to use, the problem is not that finite beings aren’t sufficiently rational, it’s that your method doesn’t work.” (@nostalgebraist re Bayes, but applies to many rationalist fantasies.)http://nostalgebraist.tumblr.com/post/161645122124/bayes-a-kinda-sorta-masterpost …

        Worth noting that this was written before Eliezer's "Toolbox-thinking and Law-thinking"; several LW commenters seem to feel that that the T-T & L-T post addresses the criticisms in this post (based on the comments at https://www.lesswrong.com/posts/gsQjde3qeZw36arYE/nostalgebraist-bayes-a-kinda-sorta-masterpost … ).

        I disagree that this answers my criticisms. In particular, my section 7 argues that it's practically unfeasible to even write down most belief/decision problems in the form that the Bayesian laws require, so "were the laws followed" is generally not even *well-defined*.

        It just occured to me that rationalisms are kind of deontological epistemologies. Not only the business of trying to reduce cognition to adherence to rules but also emotional dynamics seems similar. Does it make sense to you?

        Hmm, I’m not sure… say more, maybe? Bayesian rationalism is similar to utilitarianism, formally. I can’t make any sense of critical rationalism, but maybe it’s similar to virtue ethics?

        I’m probably missing the point here but there are plenty of puzzles with solutions that are unsolvable regardless of endless compiting power , see Yanofskyhttps://mitpress.mit.edu/books/outer-limits-reason …
