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) …

Replying to @Meaningness
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.
