(It would be nice if we could just reply with an emoji or an upvote or something to spread positivity without cluttering things with empty words…)
Thinking that he would have turned 98 today, it’s not so far-fetched to imagine him still being alive into the fully digital age. I wonder how he might have adapted his practice with the tools we have now.
(Or perhaps he did say something about digital tools back in the ’90s. Computers and the internet were already becoming commonplace in knowledge work by then.)
I believe he made a few statements about computerizing his collection. Some of them may be quoted here in the forum iirc.

The capability to upvote posts was on the forum for a short while, but then removed again - not sure why (I liked it). You can certainly just reply with an emoji - either the built-in one (type a colon and then select)
or inserted from the character viewer on the Mac 😎 .
An old school forum like this adds all the overhead around a simple, one-character emoji response, making it louder than it needs to be.
I'm not really a fan of texting/short-message culture that only satisfies the desire for recognition, so I'm not really complaining, though. But the utility of emoji is its ability to convey emotions that are hidden behind texts through just a character. So verbosity kills its beauty.
Niklas Luhmann and the Question of Digital Thinking
Why He Rejected Computers – and Why His Method Outlived That Rejection
Introduction
Niklas Luhmann is today frequently cited in discussions of digital note-taking systems, personal knowledge management, and networked thinking. His Zettelkasten has become a reference point for software tools that promise non-linear knowledge growth and intellectual productivity. At the same time, it is well documented that Luhmann himself experimented briefly with computers and abandoned them.
This apparent contradiction invites a careful question:
What exactly did Luhmann object to in digital tools, and how does his position translate into the present?
I argue that Luhmann’s reservations were neither technophobic nor nostalgic. Rather, they were grounded in a precise understanding of cognition, communication, and epistemic productivity. His rejection of computers was contingent on the form of digital tools available to him - not on the principle of digitality itself. In fact, many contemporary digital Zettelkasten systems can be understood as late technical realizations of Luhmann’s methodological insights.
1. Luhmann’s Empirical Encounter with Computers
Luhmann did not ignore digital technology. In the 1980s, he briefly used a computer for text processing. He later described this experience as unproductive and abandoned it.
The most frequently cited source is the interview “Kommunikation mit Zettelkästen” (1987), in which Luhmann reflects on his working methods. There, he explains that computers encouraged linear writing and continuous revision, while his own intellectual productivity depended on interruption, fragmentation, and recombination.
Crucially, Luhmann does not claim that computers are incapable of storing or processing information. His objection concerns their epistemic affordances: they structure attention, sequence operations, and stabilize texts too early in the thinking process.
2. The Core Objection: Linearity and Premature Closure
Luhmann’s central concern can be summarized as follows:
Productive thinking requires systems that delay closure and maximize the possibility of unexpected connections.
In his paper-based Zettelkasten, ideas existed as relatively autonomous units. Notes could be linked across contexts, revisited years later, and reinterpreted without being subordinated to a linear manuscript. The system was deliberately inconvenient in a productive way: it resisted smoothness.
By contrast, early word processors encouraged:
For Luhmann, this led to premature coherence - texts became orderly before ideas had fully matured.
3. Computers as Media, Not Thinking Systems
Luhmann’s critique is grounded in his systems theory of communication. From this perspective:
In The Science of Society (1992), Luhmann repeatedly emphasizes that knowledge does not accumulate through storage alone, but through selective connections and recursive operations. A system becomes productive when it can surprise itself.
The Zettelkasten fulfilled this function: it acted as a second-order system that introduced irritations into Luhmann’s thinking. Early computers, in his experience, did not.
4. Not a Theory of Digitalisation - and Why That Matters
It is notable that Luhmann did not develop a systematic theory of digital media or computer technology. This absence is often misinterpreted as a lack of awareness of technological change. A more precise reading suggests that Luhmann did not consider digitalisation a categorical epistemic rupture in the sense of a break in the basic operations of meaning and communication.
For him, computers were another medium of communication - important, powerful, but not transformative per se. What mattered was whether a medium supported:
Without these features, no medium - digital or analog - could serve as a genuine thinking partner.
5. Re-reading Luhmann in the Age of Digital Zettelkasten Systems
From this perspective, many contemporary digital tools do not contradict Luhmann’s method but realize it technically:
Search functions replace physical index cards without imposing sequence.
What Luhmann rejected was not digitality, but smoothness - systems that optimize efficiency at the cost of intellectual friction.
In this sense, modern digital Zettelkasten systems can be understood as an answer to the limitations Luhmann encountered, not as a refutation of his principles.
Niklas Luhmann’s rejection of computers was neither absolute nor philosophical in the abstract. It was grounded in a concrete assessment of how specific tools shaped thinking. He rejected systems that enforced linearity, premature closure, and textual smoothness. This is even reflected in his use of typewriters and the typing process of his scripts by a secretary, which allowed him to maintain a non-linear and open-ended approach to his work.
At the same time, his core methodological insight - that thinking requires systems capable of surprising their user - has proven remarkably durable. Digital tools that embrace non-linearity, fragmentation, and recursive linking align closely with this insight.
Thus, the paradox resolves itself:
Luhmann was not “against” digital thinking. He was against tools that think too neatly.
His legacy is not a preference for paper, but a demand that our tools remain epistemically demanding - whether analog or digital. It seems likely, though not demonstrable, that Luhmann himself would have continued to work with his paper slips.
Thanks you. I don't know if this is an LLM output or from your zettel, but it's a wonderful summary of what Luhmann thought about the role of computers in the Zettelkasten back in the 1980s.
I suspect the efficiency and "shortcut" introduced by digital tools have been both a blessing and a curse this century. The trend has affected not just knowledge work but human communication in general (e.g., social media...).
What we need now seems to be some mechanism to slow or deter the process so that things work better within the limits of human adaptability. With digital Zettelkasten tools, I believe it's possible to impose such artificial limitations ourselves. Then, I bet Luhmann would not reject digital methods outright.
