      From @Meaningness - “Reasonableness works directly with reality, whereas rationality works with formalisms. Rationalism assumes that a formalism somehow reflects reality, and glosses over questions about how that works.” https://meaningness.com/eggplant/reasonableness …

      I think this articulates the strain in your writing that has always felt wrong to me. I agree about the dangers of believing your formalism somehow really is reality. I don't think any cognitive process can work "directly with reality" rather than through models and formalisms.

      Ah, interesting… I hope that reading that part of the book will change your mind! An intuition pump, maybe: do insects use models and formalisms? Bacteria? Even bacteria interact with the world in complex, goal-directed, effective ways.

          Another intuition pump: a person is just physical stuff (unless you believe in mind/body dualism, which I’d guess you don’t). You are coupled with your environment by physical causality; photons bounce off your breakfast and trigger chemical reactions in retinal cells that >

          I argue (fictionally) in my novel Reality that photons hitting the retina and triggering neurons firing and chemical changes in the brain can *not* account for why a glimpse of something can make a man feel optimistic. That requires meaning, which physics deliberately avoids./1

          I might be introducing a distinction or two that you're not, but I think they're important. To start with a hopefully not controversial example: if we have, like, a rock, it isn't using models, but it also isn't doing anything I would call "cognition". Or "reasonable".

          In contrast, anything with a visual system is _definitely_ using models. The visual system is taking in a tremendous amount of data, throwing most of it away, and building a super faillible model of the world; this is why optical illusions work.
