      🧵 inspired by @cdutilhnovaes’ _Formal Languages in Logic_, about why formality is useful. Her overall explanation of how formal rationality works is closely similar to mine in _The Eggplant_ draft, so it was exciting reading! https://amzn.to/2NQNsxa

      The traditional explanation for the power of logic is “expressive precision,” but the experience of attempting to use logic in AI is that it totally fails for that. Specifically, whenever it encounters nebulosity, which is the main point of Part I of _The Eggplant_.

      Another traditional virtue of logic is truth preservation (true premises => true conclusions); but there are nearly no absolute truths in the eggplant-sized world, and deduction does not preserve mostly-truth. So that’s not the answer outside applications in math and CS.pic.twitter.com/JZBRjPqrUH

      “Dual process theories” say we have an innate rationality module that does logic correctly, plus an irrationality module that messes it up. (This goes back to the Greeks.) In a recent 🧵 I pointed out several reasons this is wrong and has damaged cogsci.https://twitter.com/Meaningness/status/1079802460124766215 …

      @cdutilhnovaes’s book [quote below], and the others I’ll cite in this 🧵, treat logic as a culturally-evolved technology for particular sorts of reasoning.

      Mostly we do formal reasoning on paper, or a blackboard or whiteboard. Some bits are best done in the shower, but most of it critically depends on these external material technologies. Richard Feynman got this:pic.twitter.com/zAFeMumKm0

      Rationalism holds that rationality works by abstracting a concrete problem into an immaterial formal realm. This is a weird flex, inasmuch as modern rationalists are usually passionately committed to materialism. Can we do formal logic without spooks? Yes we can!pic.twitter.com/nOa4A8fFGZ

      Taking formal reasoning as typically a publicly observable, material activity exorcizes the banshees. But, there’s something right about the “abstraction” idea. How and when and why does this work? [Eggplant text here and in last, not @cdutilhnovaes]pic.twitter.com/gXxLc31Bme

      The essential problem faced by “mere reasonableness”—informal rationality—is the unenumerability of potentially relevant background factors. Part II of The Eggplant explains how that works. (In part: cross the river when you come to it.)pic.twitter.com/LHdfQBbzpt

      In the Cognitive Reflection Test, you have to forcefully inhibit your informal reasoning, which gets wrong answers. Nice analysis from @drossbucket! @cdutilhnovaes gives similar examples from the Wason selection task: real-world relevance interferes. https://drossbucket.wordpress.com/2018/12/12/the-bat-and-ball-problem-revisited/comment-page-1/ …pic.twitter.com/gS9ykxsecE

          Reasoning with external material formal notation (squiggles on paper) accomplishes abstraction in two ways discussed by @cdutilhnovaes: de-semantification and ease of calculation.

          De-semantification: If you read the word “raven” you usually get a visual image and are primed with all your background knowledge of ravens. Writing ɸ(x) instead of “is a raven” strips that off, and thereby inhibits the “merely reasonable” ways of thinking.

          Humans evolved for concrete sensorimotor activity (e.g. foraging) and for social relationship maintenance. We didn’t evolve for formal rationality; unfortunately there is no “System 2” logic box in the brain, and we are terrible at it. We can manage only with external aids…

          A well-designed formalism, skillfully deployed, makes each next calculation step *visually obvious* and therefore difficult to screw up. Mathematicians speak of calculative rationality as “symbol pushing” because at a felt level that’s exactly what we’re doing.

          Examples: Putting terms in a commutative expression in the right order helps a lot even though “logically” it makes no difference. Align key symbols in formulae vertically on the page to group analogous clauses to make it clear what the next step is.

          Einstein notation replaces enormously complicated algebraic work with visually simple sub/superscript fiddling that analogizes kinesthetically to physically moving things around by hand.

          “Ethnomethodology” is basically the empirical study of rationality, both informal and formal, considered as an embodied, situated, material, social and cultural activity. Unfortunately it has its own jargon plus methodological issues; but seems directly relevant to your work.
