Day 2: Workshops29:07.2013 Cybernetics and Learning B.Scott,
How did Cybernetics influence other disciplines? Psychology-Behaviourism. Gordon Pask's 'cognitive revolution'.
(sounds like Dupuy: The Mechanization of the Mind. The story of how cybernetics kicked off the research into cognitive sciences.)
St.Gallen influenced by Vester and Stafford Beer.
Pask: 'Conversation theory'. (Still don't understand what that is, it is never properly explained.): Open University also implemented ideas of Stafford Beer (which ones?) when it was founded.
Spiral curriculum: Piaget, Jerome Bruner?, revisit cybernetic circuits in equilibrium, Pask: 'I have a 'concept', an entailment mesh; episodic memory. Expectations: Making descriptions of what we have learned; speak, so others may learn as well.
Coherence of the knowledge domain: No holes or gaps or contradictions. (The observer is making distinctions.) Who decides what a contradiction is? "I am a facilitator", (we are the facilitated?). Pask: Why does contradiction. overshadow everything else? Learning machines - not thinking machines (1960). Pask would make incredibly complex diagrams.
Book: Pickering: The cybernetic brain.
Describes performatively how we developed our -ologies, but stops before epistemology. Neuro-science - now brain science. Neuro was about the nervous system - this is about more. As if seeing a scan and having a theory was an explanation. "Monism' (Pask) is a conflation, in the sense of that the map is not the territory. Systems like us are energetically open.
Ashby: "Cybernetics is the study of all possible machines."
"Organisationally closed' computers are easier to understand.
If we understand them, they cannot surprise us.
Machine = system
A system is that which persists.
Frank George?: A theory is a model together with its interpretation. Theorising needs to anchor.
Pask: "Cybernetics is the art and science of manipulating defensible metaphors, showing how they can be constructed and what can be inferred as a result of their existence."
Analogy: Hand is to glove as foot is to sock.
Meta-phor: to carry over
Pask:
- The observer distinguishes the system and its environment.
(e.g. a cloud of smoke.)
- Energetically open and closed systems.
- Organisationally open and closed systems. (Computer: yes/no - people: blabla)
- Complex adaptive systems = self-organising (Ashby)
- Autopoetic systems, allopoetic systems
- Taciturn system, language oriented system
- serial, parallel, concurrent processes (careful here with the word 'information', it is the same thing that a system finds useful.)
Its a contradiction.
Beer called it this, Ashby called it that. Ideas are isomorphic.
Heinz von Foerster:
The rate of change of redundancy/order is always positive. It is eating up its disordered environment. It has to add in its disturbance in order not to stop. Lego: Imagine a large pile of lego. When all blocks are used up > get more blocks! (Remember we want to play an infinite game, not a finite one!)
A system will always grow, it will always escape us. Any self-organising system is non trivial. (Heinz von Foerster wrote papers about this in the early 1960s.)
We are constructing our own order. (The body-brain constructing a reality?) How can we make sure there is a world? If in our ordering of the world we distinguish other systems like ourselves that do the same. This is the argument against solipsism!
All learning requires forgetting. Structural changes also include forgetting.
These are the consequences of epistemology: There is always a point of reference outside the frame of the observer. (Systems that draw their logic from outside and act irrationally.) e.g. Christianity.
The goal of a system is what it does. (Evolution is always in the present, it has no goal.) e.g. If banks ruin the economy this is their goal. Unintended consequences acceptable.
Hierarchy, heterarchy: Principle of redundancy of potential command. In the navy the ship that first spots the enemy takes over the command.
Heinz von Foerster's distinctions: There is nothing new added from 2nd order to 3rd order observation. What is introduced from 1st to 2nd is a reflective element. So while 'i is a reflector of infinite order' we nevertheless are limited.
We see 'i' through the other (Piaget). Additionally 'self' is a social process (Luria, Vygotsky). Let us learn to be(come) who we are.
> Epistemology of the observer
What is learning? What do we learn? What helps us to learn? Adapting complex systems of behaviour.
2nd order cycle a step towards a philosophy of science. Persuade others of constructivist epistemology.
Knowledge = explanations
Skills = how to do things
People have their own theoretical models how things work. > Chinese kulis on steamship 'feeding the dragon'.
Three learning outcomes:
- Knowledge, skills
- emotion, attitude
- professional attitudes
Learning theory first principles.
The environment contains no information, it is as it is.
Identify systems that inhibit learning. e.g. Religion, Dogma, Dawkins.
