One of the major affordances of using a zettelkasten or card index for writing is that it forces the writer to break things down into their constituent parts, thereby making the entire process of writing far easier and less complex. One can separately focus their attention on the smaller steps of collecting, selecting, and arranging the material before beginning to actually write.

Niklas Luhmann indicates that it may take a number of years to reach critical mass. This may be different for everyone based on the number of ideas they place into it and the amount of work they do in creating connections.

Ward Cunningham, the creator of the wiki, has indicated that he thinks it takes roughly 500 pages in a wiki for the value to begin emerging.†

How many notes and what level of links/complexity is a good minimal threshold for one to be able to see interesting and useful results?

Google translation:

The sheer quantity exceeds the possibilities of book publication, the complex, multidimensional structure of a networked information base cannot be reproduced in print, and finally the dynamic of a constantly growing and constantly correcting material does not fit into the rigid rhythm of book production, in which each expanded and corrected new edition is associated with an incalculable amount of effort. A book publication could only offer a snapshot of such a database, reduced to a specific perspective. This too can be very useful from time to time, but it does not solve the problem of publishing the entire material.

While the writing criticism of "dumping out one's zettelkasten" into a paper, journal article, chapter, book, etc. has been reasonably frequent in the 20th century, often as a means of attempting to create a linear book-bound context in a local neighborhood of ideas, are there other more complex networks of ideas which we're not communicating because they don't neatly fit into linear narrative forms? Is it possible that there is a non-linear form(s) based on network theory in which more complex ideas ought to better be embedded for understanding?

Some of Niklas Luhmann's writing may show some of this complexity and local or even regional circularity, but perhaps it's a necessary means of communication to get these ideas across as they can't be placed into linear forms.

One can analogize this to Lie groups and algebras in which our reading and thinking experiences are limited only to local regions which appear on smaller scales to be Euclidean, when, in fact, looking at larger portions of the region become dramatically non-Euclidean. How are we to appropriately relate these more complex ideas?

What are the second and third order effects of this phenomenon?

An example of this sort of non-linear examination can be seen in attempting to translate the complexity inherent in the Wb (Wörterbuch der ägyptischen Sprache) into a simple, linear dictionary of the Egyptian language. While the simplicity can be handy on one level, the complexity of transforming the entirety of the complexity of the network of potential meanings is tremendously difficult.

9/8b2 "Multiple storage" as a necessity of<br /> storage of complex (complex<br /> evaluating) information.

Fascinating to see the English phrase "multiple storage" pop up in Luhmann's ZKII section on Zettelkasten.

This note is undated, though being in ZKII likely occurred more than a decade after he'd started his practice. One must wonder where he pulled the source for the English phrase rather than using a German one? Does the idea appear in Heyde? It certainly would have been an emerging question within systems theory and potentially computer science ideas which Luhmann would have had access to.

Do folgezettel in combination with an index help to prevent over-indexing behaviors? Or the scaling problem of categorization in a personal knowledge management space?

Where do subject headings within a zettelkasten dovetail with the index? Where do they help relieve the idea of heavy indexing or tagging? How are the neighborhoods of ideas involved in keeping a sense of closeness while still allowing density of ideas and information?

Having digital search views into small portions of neighborhoods like gxabbo suggested can be a fantastic affordance. see: https://hypothes.is/a/W2vqGLYxEe2qredYNyNu1A

For example, consider an anthropology student who intends to spend a lifetime in the subject and its many sub-areas. If they begin smartly tagging things with anthropology as they start, eventually the value of the category, any tags, or ideas within their index will eventually grow without bound to the point that the meaning or value as a search affordance within their zettelkasten (digital or analog) will be utterly useless. Let's say they fix part of the issue by sub-categorizing pieces into cultural anthropology, biological anthropology, linguistic anthropology, archaeology, etc. This problem is fine while they're in undergraduate or graduate school for a bit, but eventually as they specialize, these areas too will become overwhelming in terms of search and the search results. This problem can continue ad-infinitum for areas and sub areas. So how can one solve it?

Is a living and concatenating index the solution? The index can have anthropology with sub-areas listed with pointers to the beginnings of threads of thought in these areas which will eventually create neighborhoods of these related ideas.

The solution is far easier when the ideas are done top-down after-the-fact like in the Dewey Decimal System when the broad areas are preknown and pre-delineated. But in a Luhmann-esque zettelkasten, things grow from the bottom up and thus present different difficulties from a scaling up perspective.

How do we classify first, second, and third order effects which emerge out of the complexity of a zettelkasten? - Sparse indexing can be a useful long term affordance in the second or third order space. - Combinatorial creativity and ideas of serendipity emerge out of at least the third order. - Using ZK for writing is a second order affordance - Storage is a first order affordance - Memory is a first order affordance (related to storage) - Productivity is a second+ order (because solely spending the time to save and store ideas is a drag at the first order and doesn't show value until retrieval at a later date). - Poor organization can be non-affordance or deterrent which results in a scrap heap - lack of a reason why can be a non-affordance or deterrence as well - cross reference this list and continue on with other pieces and affordances

Index card systems were insanely popular in the early 1900's for note taking and uses of all other sorts (business administration, libraries, etc.). The note taking tradition of the slip box goes back even further in intellectual history with precedents including miscellanies, commonplace books, and florilegia. Konrad Gessner may have been one of the first to have created a method using slips of rearrangeable paper in the 1500s, but this general pattern of excerpting, note taking and writing goes back to antiquity with the concept of locus communis (Latin) and tópos koinós (Greek).

What some intellectual historians are hoping for evidence of in this particular source is a possible origin of the idea of the increased complexity of direct links from one card to another as well as the juxtaposition of ideas which build on each other. Did Luhmann innovate this himself or was this something he read or was in general practice which he picked up? Most examples of zettelkasten outside of Luhmann's until those in the present, could be described reasonably accurately as commonplace books on index cards usually arranged by topic/subject heading/head word (with or without internal indices).

Perhaps it was Luhmann's familiarity with Aktenzeichen (German administrative "file numbers") prior to his academic work which inspired the dramatically different form his index card-based commonplace took? See: https://hyp.is/CqGhGvchEey6heekrEJ9WA/www.wikiwand.com/de/Aktenzeichen_(Deutschland)

Is it possible that he was influenced by Beatrice Webb's ideas on note taking from Appendix C of My Apprenticeship (1924) which was widely influential in the humanities and particularly sociology and anthropology? Would he have been aware of the work of historians Ernst Bernheim followed by Charles Victor Langlois and Charles Seignobos? (see: https://hypothes.is/a/DLP52hqFEe2nrIMdrd4U7g) Did Luhmann's law studies expose him to the work of jurist Johann Jacob Moser (1701-1785) who wrote about his practice in his autobiography and subsequently influenced generations of practitioners including Jean Paul and potentially Hegel?

There are obviously lots of unanswered questions...

These always read as hyperbole to me, but it's difficult to explain the surprise and serendipity of re-finding things in one's notes on a regular basis. It's akin to the sort of cognitive dissonance that religious people have when encountering the levels of complexity formed by living systems through evolution. Not having better words for describing the experience, they may resort to descriptions of magic or religion to frame their experiences.

subjects cannot be described in terms of a strictly hierarchical order, it is rather a form of loose coupling insofar as one can find lower-level subjects which do not fit systematically to the top-level issue but show only marginally connections.

There is something suspiciously similar about the instantiation of a zettelkasten and the idea of small pieces loosely joined.

Perhaps also related to the idea of a small number of primitives which can interact in a small number of ways, but which gives rise to incredible complexity.

Every element receives its value based on the network of links and connections it has with other elements. This is just as true for ideas on index cards in a zettelkasten as it is for people within a society.

idea/index card:zettelkasten :: person:society

What other elements in complex systems is this analogy true for? Is it a truism for all elements in complex systems? What other examples can we come up with?

Continuing on the analogy between addresses for zettels/index cards and for people, the differing contexts for cards and ideas is similar to the multiple different publics in which people operate (home, work, school, church, etc.)

Having these multiple publics creates a variety of cross links within various networks for people which makes their internal knowledge and relationships more valuable.

As societies grow the number of potential interconnections grows as well. Compounding things the society doesn't grow as a homogeneous whole but smaller sub-groups appear creating new and different publics for each member of the society. This is sure to create a much larger and much more complex system. Perhaps it's part of the beneficial piece of the human limit of memory of inter-personal connections (the Dunbar number) means that instead of spending time linearly with those physically closest to us, we travel further out into other spheres and by doing so, we dramatically increase the complexity of our societies.

Does this level of complexity change for oral societies in pre-agrarian contexts?

What would this look like mathematically and combinatorially? How does this effect the size and complexity of the system?

How can we connect this to Stuart Kauffman's ideas on complexity? (Picking up a single thread creates a network by itself...)

Modern digital zettelkasten don't force the same sort of digital internal branching process that is described by Niklas Luhmann. Internal branching in these contexts is wholly reliant on the user to create it.

Many digital systems will create a concrete identifier to fix the idea within the system, but this runs the risk of ending up with a useless scrap heap.

Some modern systems provide the ability for one to add taxonomies like subject headings in a commonplace book tradition, which adds some level of linking. But if we take the fact that well interlinked cards are the most valuable in such a system then creating several links upfront may be a bit more work, but it provides more value in the long run.

Upfront links also don't require quite as much work at the card's initial creation as the creator already has the broader context of the idea. Creating links at a future date requires the reloading into their working memory of the card's idea and broader context.

Of course there may also be side benefits (including to memory) brought by the spaced repetition of the card's ideas as well as potential new contexts gained in the interim which may help add previously unconsidered links.

It can certainly be possible that at some level of linking, there is a law of diminishing returns the decreases the value of a card and its idea.

One of the benefits of physical card systems like Luhmann's is that the user is forced to add the card somewhere, thus making the first link of the idea into the system. Luhmann's system in particular creates a parent/sibling relation to other cards or starts a brand new branch.

There's an interesting analogy between Niklas Luhmann's zettelkasten numbering system and the early street address system in Vienna. Just as people (often) have a fixed address, they're able to leave it temporarily and mix with other people before going back home every night. The same is true with his index cards. Without the ability to remove cards and remix them in various orders, the system has far less complexity and simultaneously far less value.

Link to reference of street addressing systems of Vienna quoted by Markus Krajewski in (chapter 3 of) Paper Machines.

Both the stability and the occasional complexity of the system give it tremendous value.

How is this linked to the idea that some of the most interesting things within systems happen at the edges of the system which have the most complexity? Cards that sit idly have less value for their stability while cards at the edges that move around the most and interact with other cards and ideas provide the most value.

Graph this out on a multi-axis drawing. Is the relationship linear, non-linear, exponential? What is the relationship of this movement to the links between cards? Is it essentially the same (particularly in digital settings) as movement?

Are links (and the active creation thereof) between cards the equivalent of communication?

1. Cf. Schmidt, ‘Luhmanns Zettelkasten’, 7. The heading of this file card is formulated in form of a question: ‘Geist im Kasten?’ (‘Does Spirit hide in the filing cabinet?’). Obviously, the answer is no. Many thanks to Johannes Schmidt for providing the image of this file card.

In a zettel in his system entitled "Does Spirit hide in the filing cabinet", Niklas Luhmann wrote the note: "People come, they see everything and nothing more than that, just like in porn movies; consequently, they leave disappointed." This is a telling story about the simplicity of the idea of a slip box (zettelkasten, card catalog, or commonplace book).

Niklas Luhmann, Zettelkasten II, index card no. 9/8,3

It's also a testament to the fact that the value of it is in the upfront work that is required in making valuable notes and linking them. Many end up trying out the simple looking system and then wonder why it isn't working for them. The answer is that they're not working for it.

For complexity to flourish between various projects and ideas, folders are probably not the final solution. Within a zettelkasten, other emergent structures may emerge to deal with information that doesn't fit neatly into any particular folder or other structure.

The Intermediate Packet approach allows you to reuse previously built packets for new projects

By incorporating existing packets in new projects, you gain the ability to deliver new projects much faster.
