combinatorial creativity

A #zettelkasten or commonplace provides a catalytic surface to which ideas in the “solution of life” can more easily adhere to speed their reaction with ideas you’ve already seen and collected.
Once combined via linking, further thinking and writing, they can be released as novel ideas for everyone to use.

On The Interdisciplinarity of Zettelkasten: Card Numbering, Topical Headings, and Indices

As humans we’re terrifically spectacular at separating things based on perceived categories. The Dewey Decimal System systematically separates mathematics and history into disparate and distinct locations, but your zettelkasten shouldn’t force this by overthinking categories. Perhaps the overlap of math and history is exactly the interdisciplinary topic you’re working toward? If this is the case, just put cards into the slip box closest to their nearest related intellectual neighbor—and by this I mean nearest related to your way of thinking, not to Melvil Dewey’s or anyone else. Over time, through growth and branching, ideas will fill in the interstitial spaces and neighboring ideas will slowly percolate and intermix. Your interests will slowly emerge into various bunches of cards in your box. Things you may have intially thought were important can separate away and end up on sparse branches while other areas flourish. If you make the (false) choice to separate math and history into different “sections” it will be much harder for them to grow and intertwine in an organic and truly interdisciplinary way. Universities have done this sort of separation for hundreds of years and as a result, their engineering faculty can be buildings or even entire campuses away from their medical faculty who now want to work together in new and exciting interdisciplinary ways. This creates a physical barrier to more efficient and productive innovation and creativity. It’s your zettelkasten, so put those ideas right next to each other from the start so they can do the work of serendipity and surprise for you. Do not artificially separate your favorite ideas. Let them mix and mingle and see what comes out of them.

If you feel the need to categorize and separate them in such a surgical fashion, then let your index be the place where this happens. This is what indices are for! Put the locations into the index to create the semantic separation. Math related material gets indexed under “M” and history under “H”. Now those ideas can be mixed up in your box, but they’re still findable. DO NOT USE OR CONSIDER YOUR NUMBERS AS TOPICAL HEADINGS!!! Don’t make the fatal mistake of thinking this. The numbers are just that, numbers. They are there solely for you to be able to easily find the geographic location of individual cards quickly or perhaps recreate an order if you remove and mix a bunch for fun or (heaven forfend) accidentally tip your box out onto the floor. Each part has of the system has its job: the numbers allow you to find things where you expect them to be and the index does the work of tracking and separating topics if you need that.

The broader zettelkasten, tools for thought, and creativity community does a terrible job of explaining the “why” portion of what is going on here with respect to Luhmann’s set up. Your zettelkasten is a crucible of ideas placed in juxtaposition with each other. Traversing through them and allowing them to collide in interesting and random ways is part of what will create a pre-programmed serendipity, surprise, and combinatorial creativity for your ideas. They help you to become more fruitful, inventive, and creative.

Broadly the same thing is happening with respect to the structure of commonplace books. There one needs to do more work of randomly reading through and revisiting portions to cause the work or serendipity and admixture, but the end results are roughly the same. With a Luhmann-esque zettelkasten, it’s a bit easier for your favorite ideas to accumulate into one place (or neighborhood) for easier growth because you can move them around and juxtapose them as you add them rather than traversing from page 57 in one notebook to page 532 in another.

If you use your numbers as topical or category headings you’ll artificially create dreadful neighborhoods for your ideas to live in. You want a diversity of ideas mixing together to create new ideas. To get a sense of this visually, play the game Parable of the Polygons in which one categorizes and separates (or doesn’t) triangles and squares. The game created by Vi Hart and Nicky Case based on the research of Thomas Schelling (Dynamic Models of Segregation, 1971) provides a solid and visual example of the sort of statistical mechanics going on with ideas in your zettelkasten when they’re categorized rigidly. If you rigidly categorize ideas and separate them, you’ll drastically minimize the chance of creating the sort of useful serendipity of intermixed and innovative ideas. A zettelkasten isn’t simply the aggregation repository many use it for—it’s a rumination device, a serendipity engine, a creativity accelerator. To get the best and most of this effect, one must carefully help to structure their card index to generate it.

It’s much harder to know what happens when you mix anthropology with complexity theory if they’re in separate parts of your mental library, but if those are the things that get you going, then definitely put them right next to each other in your slip box. See what happens. If they’re interesting and useful and they’ve got explicit numerical locators and are cross referenced in your index, they are unlikely to get lost. Be experimental occasionally. Don’t put that card on Henry David Thoreau in the section on writers, nature, or Concord, Massachusetts—especially if those aren’t interesting to you. Besides, everyone has already worn down those associative trails, paved them, and re-paved them. Instead put him next to your work on innovation and pencils because it’s much easier to become a writer, philosopher, and intellectual when your family’s successful pencil manufacturing business can pay for you to attend Harvard and your house was always full of writing instruments from a young age. Now you’ve got something interesting and creative. (And if you really must, you can always link the card numerically to the other transcendentalists across the way.)

In case they didn’t hear it in the back, I’ll shout it again:

ACTIVELY WORK AGAINST YOUR NATURAL URGE TO USE YOUR ZETTELKASTEN NUMBERS AS TOPICAL HEADINGS! MIX IT UP INSTEAD.

Review of “On Intellectual Craftsmanship” (1952) by C. Wright Mills

In “On Intellectual Craftsmanship” (1952), C. Wright Mills talks about his methods for note taking, thinking, and analysis in what he calls “sociological imagination”. This is a sociologists’ framing of their own research and analysis practice and thus bears a sociological related name. While he talks more about the thinking, outlining, and writing process rather than the mechanical portion of how he takes notes or what he uses, he’s extending significantly on the ideas and methods that Sönke Ahrens describes in How to Take Smart Notes (2017), though obviously he’s doing it 65 years earlier. It would seem obvious that the specific methods (using either files, note cards, notebooks, etc.) were a bit more commonplace for his time and context, so he spent more of his time on the finer and tougher portions of the note making and thinking processes which are often the more difficult parts once one is past the “easy” mechanics.

While Mills doesn’t delineate the steps or materials of his method of note taking the way Beatrice Webb, Langlois & Seignobos, Johannes Erich Heyde, Antonin Sertillanges, or many others have done before or Umberto Eco, Gerald Weinberg, Robert Greene/Ryan Holiday, Sönke Ahrens, or Dan Allosso since, he does focus more on the softer portions of his thinking methods and their desired outcomes and provides personal examples of how it works and what his expected outcomes are. Much like Niklas Luhmann describes in Kommunikation mit Zettelkästen (VS Verlag für Sozialwissenschaften, 1981), Mills is focusing on the thinking processes and outcomes, but in a more accessible way and with some additional depth.

Because the paper is rather short, but specific in its ideas and methods, those who finish the broad strokes of Ahrens’ book and methods and find themselves somewhat confused will more than profit from the discussion here in Mills. Those looking for a stronger “crash course” might find that the first seven chapters of Allosso (2022) along with this discussion in Mills is a straighter and shorter path.

While Mills doesn’t delineate his specific method in terms of physical materials, he does broadly refer to “files” which can be thought of as in the zettelkasten (slip box) or card index traditions. Scant evidence in the piece indicates that he’s talking about physical file folders and sheets of paper rather than slips or index cards, but this is generally irrelevant to the broader process of thinking or writing. Once can easily replace the instances of the English word “file” with the German concept of zettelkasten and not be confused.

One will note that this paper was written as a manuscript in April 1952 and was later distributed for classroom use in 1955, meaning that some of these methods were being distributed directly from professors to students. The piece was later revised and included as an appendix to Mill’s text The Sociological Imagination which was first published in 1959.

Because there aren’t specifics about Mills’ note structure indicated here, we can’t determine if his system was like that of Niklas Luhmann, but given the historical record one could suppose that it was closer to the commonplace tradition using slips or sheets. One thing becomes more clear however that between the popularity of Webb’s work and this (which was reprinted in 2000 with a 40th anniversary edition), these methods were widespread in the mid-twentieth century and specifically in the field of sociology.

Above and beyond most of these sorts of treatises on note taking method, Mills does spend more time on the thinking portions of the practice and delineates eleven different practices that one can focus on as they actively read/think and take notes as well as afterwards for creating content or writing.
