E46: How do metaphors work?
Conceptual metaphor is a theory in cognitive science that claims understanding and problem-solving often (but not always) happen via systems of metaphor. I present the case for it, and also expand on the theory in the light of previous episodes on ecological and embodied cognition. This episode is theory. The next episode will cover practice.This is the beginning of a series roughly organized around ways of discovering where your thinking has gone astray, with an undercurrent of how techniques of literary criticism might be applied to software documents (including code). Books I drew uponAndrew Ortony (ed.), Metaphor and Thought (2/e), 1993 (four essays in particular: see the transcript).Lakoff and Johnson, Metaphors We Live By, 1980. (I worked from the first edition; there is a second edition I haven't read.)Two of the Metaphor and Thought essays have PDFified photocopies available:Reddy's "The Conduit Metaphor – A Case of Frame Conflict in Our Language About Language"Lakoff's "The Contemporary Theory of Metaphor"Other things I referred toHelper T cellsRichard P.

E45: The offloaded brain, part 5: I propose a software design style
In this podcast, the host explores a software design style inspired by ecological and embodied cognition. They discuss using Erlang-style 'processes' as core building blocks and the importance of avoiding Big Ball of Mud. The episode delves into the balance between intellectual control and biological plausibility in design decisions. Additionally, the host references Extreme Programmers' practices and test-driven design concepts for inspiration.

E44: The offloaded brain, part 4: an interview with David Chapman
David Chapman, an AI researcher, discusses his work on the Pengi program. They explore ecological software design, indexical expressions, and the implementation of a game controller. They also discuss the behavior of bee wolves and the maintenance of the AI program Pangy.

E43: The offloaded brain, part 3: dynamical systems
Scientists studying ecological and embodied cognition try to use algorithms as little as they can. Instead, they favor dynamical systems, typically represented as a set of equations that share variables in a way that is somewhat looplike: component A changes, which changes component B, which changes component A, and so on. Peculiarities of behavior can be explained as such systems reaching stable states. This episode describes two sets of equations that predict surprising properties of what seems to be intelligent behavior.Source:Anthony Chemero, Radical Embodied Cognitive Science, 2011Either mentioned or came this close to being mentionedJames Clerk Maxwell, "On Governors", 1868 (PDF)Andy Clark, Being There: Putting Brain, Body, and World Together Again, 1997Stanford Encyclopedia of Philosophy, "Embodied Cognition", 2020Stanford Encyclopedia of Philosophy, "The Computational Theory of Mind", 2021Wikipedia, "Dynamical Systems Theory"Nick Bostrom, "Letter from Utopia", 2008/20CreditsThe image is from Maxwell's "On Governors", showing the sort of equations "EEs" work with instead of code.

E42: The offloaded brain, part 2: applications
Suppose you believed that the ecological/embodied cognitive scientists of last episode had a better grasp on cognition than does our habitual position that the brain is a computer, passively perceiving the environment, then directing the body to perform steps in calculated plans. If so, technical practices like test-driven design, refactoring in response to "code smells," and the early-this-century fad for physical 3x5 cards might make more sense. I explain how. I also sketch how people might use such ideas when designing their workplace and workflow. Books I drew uponAndy Clark, Being There: Putting Brain, Body, and World Together Again, 1997Alva Noë, Action in Perception, 2005Also mentionedGary Klein, Sources of Power: How People Make Decisions, 1998I mentioned a session of the Simple Design and Test conference.The sociology book I contributed to: The Mangle in Practice: Science, Society, and Becoming, 2009, edited by Andrew Pickering and Keith Guzik. My chapter, "A Manglish Way of Working: Agile Software Development", is inexplicably available without a paywall.The MIT AI Lab Jargon FileI believe the original publication about CRC cards is Kent Beck and Ward Cunningham, "A laboratory for teaching object oriented thinking", 1989. I also believe the first book-type description was in Rebecca Wirfs-Brock et. al., Designing Object-Oriented Software, 1990. The idea of "flow" was first popularized in Mihály Csíkszentmihályi's 1990 Flow: The Psychology of Optimal Experience. The idea of the hedgehog and the fox was popularized by Isaiah Berlin in his 1953 book The Hedgehog and the Fox (a wikipedia link).The original developer of the Pomodoro technique describes it here. There was a book about it, but Goodreads has been sufficiently enshittified that I can't find it. Perhaps you might be interested in Reduce PTSD and Depression Symptoms in 21 Days Using the Pomodoro Method instead? Because Goodreads prefers that.The Boy Who Cried World (wikipedia)CreditsI was helped by Steve Doubleday, Ron Jeffries, and Ted M. Young. I took the picture of Dawn in the tango close embrace.

E41: The offloaded brain, part 1: behavior
Embodied or Ecological Cognition is an offshoot of cognitive science that rejects or minimizes one of its axioms: that the computer is a good analogy for the brain. That is, that the brain receives inputs from the senses; computes with that input as well as with goals, plans, and stored representations of the world; issues instructions to the body; and GOTO PERCEPTION. The offshoot gives a larger causal role to the environment and the body, and a lesser role to the brain. Why store instructions in the brain if the arrangement of body-in-environment can be used to make it automatic?This episode contains explanations of fairly unintelligent behavior. Using them, I fancifully extract five design rules that a designer-of-animals might have used. In the next episode, I'll apply those rules to workplace and process design. In the final episode, I'll address what the offshoot has to say about more intelligent behavior.SourcesLouise Barrett, Beyond the Brain: How Body and Environment Shape Animal and Human Minds, 2011Anthony Chemero, Radical Embodied Cognitive Science, 2011Andy Clark, Being There: Putting Brain, Body, and World Together Again, 1997Mentioned or relevantPassive Walking Robot Propelled By Its Own Weight (Youtube video)Steven Levy, Hackers: Heroes of the Computer Revolution, 1984Guy Steele, "How to Think About Parallel Programming – Not!", Strange Loop 2010.

EXCERPT: Concepts without categories
This excerpt from episode 40 contains material independent of that episode's topic (collaborative circles) that might be of interest to people who don't care about collaborative circles. It mostly discusses a claim, due to Andy Clark, that words are not labels for concepts. Rather, words come first and concepts accrete around them. As a resolute, concepts are messy. Which is fine, because they don't need to be tidy.SourcesLouise Barrett, Beyond the Brain: How Body and Environment Shape Animal and Human Minds, 2011Anthony Chemero, Radical Embodied Cognitive Science, 2011MentionedEmily Dickinson, "A narrow Fellow in the Grass", 1891 (I think version 2 is the original. Dickinson's punctuation was idiosyncratic, but early editions of her poetry conventionalized it.)Talking Heads, "Psycho Killer", 1977Andy Clark, Being There: Putting Brain, Body, and World Together Again, 1997.

EXCERPT: Christopher Alexander’s forces
Software design patterns were derived from the work of architect Christopher Alexander, specifically his book A Pattern Language: Towns, Buildings, Construction. This excerpt (from episode 39) addresses a problem: most software people don't know one of Alexander's most important ideas, that of "forces". SourcesChristopher Alexander et al, A Pattern Language: Towns, Buildings, Construction, 1977.Mentioned (or that I wish I'd found a way to mention)Gamma et al, Design Patterns, 2004Eric Evans, Domain-Driven Design, 2003. I also like Joshua Kerievsky's pattern-language-like description of study groups, "Pools of Insight".Brian Marick, "Patterns failed. Why? Should we care?", 2017 (video and transcript)"Arches and Chains" (video) is a nice description of how arches work.Ryan Singer, "Designing with forces: How to apply Christopher Alexander in everyday work", 2010 (video)CreditsBy Anneli Salo - Own work, CC BY-SA 3.0, Wikipedia Commons
