Since
@everytstudies’ post is long, and has prompted some interesting discussion: here is Sarah Constantin’s explanation of “cognitive decoupling.” It’s an aspect of systematic rationality, focusing on limiting inference. https://srconstantin.wordpress.com/2014/06/09/do-rationalists-exist/ …pic.twitter.com/1QUz9ImPoI

Systematic rationality only works if you do limit inference, because nothing is really truly true. If you take true-enough-for-this-context as “truly true,” you infer way too much. If you take it as “false,” you can’t infer anything.

The term “circumscription” was introduced by John McCarthy as a key move in the logicist program of AI (which he founded). You can’t use logic in the real world without it or something equivalent. https://en.wikipedia.org/wiki/Circumscription_(logic) …

Interesting point that applying logic to the real world requires tight limits or it stops working. Seems obviously correct but I never thought of it in exactly that way.

The _Hard Truths_ book I live-tweeted a couple days ago is largely about this point. The first 3-4 chapters are great; it bogs down in the technicalities of analytic metaphysics after that.

…. and I think my Eggplant book will do a better job covering the same material :)

Has been on hold since October, due to family responsibilities. In the last week I’ve just started to get enough free time to start doing some background reading. Will be another couple months before I can work on it in earnest, at a guess.
