"To put it super crudely it's a sort of disagreement with the idea that informal rationality is just an approximation to the math instead of the other way around." - Srijit Sanyal gives the best one-line description of @Meaningness's views I've heard. Or at least I thought so?

Srijit’s summary is a not-altogether-accurate description of the relationship between informal rationality (“reasonableness”) and formal rationality. Text here from the definitions section of my Eggplant book, which I hope can clarify! https://meaningness.com/eggplant/terms pic.twitter.com/WqXWfc3M6R

Reasonableness is entwined with perception and with concrete activity in ways that formal rationality isn’t and can’t be—so they have different functions. They’re not just different ways of doing the same thing. cc

Formal rationality has to rely on reasonableness to make contact with concrete reality. There’s always a gap of non-formal interpretation between formal symbolic understanding and the world. Recognizing this is a prerequisite to meta-rationality; but is not meta-rationality.

Meta-rationality means figuring out how to deploy formal rationality effectively in particular circumstances. That can involve examining the specifics of the rationality/reasonableness interface in those circumstances; but it goes well beyond that.pic.twitter.com/1SNXhP7Fhu

Meta-rationality often involves ontological revision: re-thinking the categories, properties, relationships, and individuation criteria that you build a rational model on. Neither reasonableness nor formal rationality involve explicit theories, criteria, or methods for that.

Meta-rationality also often evaluates, selects, combines, modifies, discovers, creates, and monitors formal systems— in order to deal with complex situations which neither reasonableness or rationality, nor any combination of the two, treats adequately.
