Alan Kay, Systems, and Textbooks

Alan Kay give a talk called “Is Computing a Liberal Art?” yesterday at the 2012 NITLE Summit. Here I discuss his key idea: that systemic thinking is a liberal art, and I explain a corollary idea, that textbooks suck.

Kay is attuned to how ideas evolve and are instantiated in the culture and the mind. For him a key piece in this process is the relationship between ideas and the categories we have for them; the relationship is this: if you don’t have a category for an idea, it’s very difficult to receive that idea.

Kay says we’re born with 300 or so preexisting categories that the species has evolved to know it needs to think about to survive, and we’re wired to be looking around for thoughts in those categories (food, shelter, pleasure, etc.). But the story of the last few hundred years is that we’ve quickly developed important ideas, which society needs to have to improve and perhaps even to continue to exist, and for which there are no pre-existing, genetically created categories. So there’s an idea-receiving capacity gap.

Education’s job should be, says Kay, to bridge this gap. To help, that is, people form these necessary new idea-receiving categories–teaching them the capacity for ideas–early on in their lives, so that as they grow they are ready to embrace the things we need them to know. Let me say that in a better way: so that as they grow they are ready to know in the ways we need them to know.

Said he, “If you have a new idea come in and education won’t teach people it from birth, you get a pop culture.” Pop culture! A harsh but fair critique of our society. More on that pop culture below.

For now, what are the ideas or categories, or what capacity for ideas should we now be teaching? Kay has one major thought in mind. He wants us to cultivate the ability to conceive of, work with, create, understand, manipulate, tinker with, disrupt, and, generally, appreciate the beauty of systems. This he hails as perhaps the most important of all the liberal arts.

It is the zeitgeist of the last 100 years that everything now appears as a system that was but a piece of a system before–or everything is now multi-dimensional that was linear before—thinking of the body as a system, the environment as a system, economics as systems, computers as systems. It’s why we talk about gamification so much–because a game, or a simulation, thought of as a thing we might create (rather than a thing we only act within), is a visceral example of systems thinking. (If this sounds familiar to readers of this blog, it’s because I’ve written about seeing systems before, in The Age of the Gums, or in Errol Morris and Spirals of Learning, or in Pieces of an Ecology of Workplace Learning, or even in The Conduit Metaphor, for instance. It might be all I write about.)

Seeing systems is an epistemology, a way of knowing, a mindset. As Kay said, “the important stuff I’m talking about is epistemological . . . about looking at systems.” It’s the Flatland story–that we need to train our 2D minds to see in a kind of 3D–and Kay’s genius is that he recognizes we have to bake this ability into the species, through education, as close to birth as possible.

One main point implied here is that we’re not talking about learning to see systems as an end point. Systems thinking is to be conceived of as a platform skill or an increased capacity on top of which we will be able to construct new sorts of ideas and ways of knowing, of more complex natures still. The step beyond seeing a single system is of course the ability to see interacting systems – a kind of meta-systemic thinking – and this is what I think Kay is really interested in, because it’s what he does. At one point he showed a slide of multiple systems–the human body, the environment, the internet, and he said in a kind of aside, “they’re all one system . . .” Compare that to the advanced stages in Bob Kegan’s constructive developmental psychology: “At Kegan’s sixth and final stage . . . there is a dawning awareness of an underlying unity that transcends human and environmental complexity.” (That from Philip Lewis’ work on Kegan, The Discerning Heart: Just happened to read that on the Metro on the way back to the hotel, as I was passing through Arlington National Cemetery).

Kay’s complaint is that higher education does not cultivate the particular epistemology of systemic thinking. We don’t teach integrative ways of knowing; we instead dwell within our disciplines, which dwelling you can see as being trapped within an arbitrarily chosen system. The point is to be able to see connections between the silos. Says Kay, the liberal arts have done a bad job at “adding in epistemology” among the “smokestacks” (i.e. disciplines).

Ok, so we’re not teaching systemic thinking. So what? What happens if you don’t teach people systemic thinking?

Then, Kay says, you’re allowing them to be stuck in whatever system they happen to be in, without thinking of it as a system. What happens when you’re stuck in a system? You don’t understand the world and yourself and others as existing in constant development, as being in process; you think you are a fixed essence or part within a system (instead of a system influencing systems) and you inadvertently trap yourself in a kind of tautological loop where you can only think about things you’re thinking about and do the things you do and you thus limit yourself to a kind of non-nutritive regurgitation of factoids, or the robotic meaningless actions of an automaton, or what Kay calls living in a pop culture. He sees this problem in higher education, where even faculty, experts in their own fields, are uneducated, in the sense that they can make no meta-connections among the fields, such that (as he said) hardly anyone exists who can understand the breadth of thought in a magnum cross-functional opus like the Principia Mathematica. And yet our future will be built on such integrative meta-connections as Newton’s.

By way of conclusion, I’ll now tell you why textbooks suck, according to Kay. A downside of being epistemologically limited to thinking within a system is that you overemphasize the importance of the content and facts as that system orders them. If you’re a teacher, you limit your students to processing bits according to a pre-ordained structure, to being a program, if you will, instead of learning to write a program. It would be better to use the system itself as the information students act upon when they construct their knowledge, and to find a way to get students to build new systems and even systems of systems. We teach students vocabulary within one set of grammatical rules, with the rules as the endpoint, say, but if we were disciples of Kay we would allow students to make grammars of grammars and languages of languages, with spirals of increasing complexity of thought looping into infinity and no endpoint in sight. That’s the order of consciousness Kay is after. Most textbooks, however, are on the stuck-within-the-system and vocab-and-grammar level. Which is why they draw Kay’s ire.
