    1. It is obvious that due to this strict logic foundation, related thoughts will not be scattered allover the box but grouped together in proximity. As a consequence, completely withoutcarbon-copying all note sheets only need to be created once.

      In a break from the more traditional subject heading filing system of many commonplacing and zettelkasten methods, in addition to this sort of scheme Heyde also suggests potentially using the Dewey Decimal System for organizing one's knowledge.

      While Luhmann doesn't use Dewey's system, he does follow the broader advice which allows creating a dense numbering system though he does use a different numbering scheme.

    1. The numbers themselves have also been a source ofdebate. Some digital users identify a new notechronologically. One I made right now, for example,might be numbered “202207201003”, which would beunique in my system, provided I don’t make another thisminute. The advantage of this system is that I could keeptrack of when I had particular ideas, which might comein handy sometime in the future. The disadvantage is thatthe number doesn’t convey any additional information,and it doesn’t allow me to choose where to insert a newnote “behind” the existing note it is most closely relatedto.

      Allosso points out some useful critiques of numbering systems, but doesn't seem to get to the two core ideas that underpin them (and let's be honest, most other sources don't either). As a result most of the controversies are based on a variety of opinions from users, many of whom don't have long enough term practices to see the potential value.

      The important things about numbers (or even titles) within zettelkasten or even commonplace book systems is that they be unique to immediately and irrevocably identify ideas within a system.

      The other important piece is that ideas be linked to at least one other idea, so they're less likely to get lost.

      Once these are dealt with there's little other controversy to be had.

      The issue with date/time-stamped numbering systems in digital contexts is that users make notes using them, but wholly fail to link them to anything much less one other idea within their system, thus creating orphaned ideas. (This is fine in the early days, but ultimately one should strive to have nothing orphaned).

      The benefit of Luhmann's analog method was that by putting one idea behind its most closely related idea was that it immediately created that minimum of one link (to the thing it sits behind). It's only at this point once it's situated that it can be given it's unique number (and not before).


      Luhmann's numbering system, similar to those seen in Viennese contexts for conscription numbers/house numbers and early library call numbers, allows one to infinitely add new ideas to a pre-existing set no matter how packed the collection may become. This idea is very similar to the idea of dense sets in mathematics settings in which one can get arbitrarily close to any member of a set.

    1. However, the great advantage of enumerations over sets is that they are ordered and they force the brain to list them always in the same order. An ordered list of countries contains more information than the set of countries that can be listed in any order. Paradoxically, despite containing more information, enumerations are easier to remember.

      Enumerations are sets with a particular order. The fact that they have an order, in which each item might be associated with the next, makes them easier to remember.

      The greater information in an enumeration provides additional structure which makes the items easier to remember.

    2. You should avoid such items whenever possible due to the high cost of retaining memories based on sets.

      Piotr Wozniak recommends against avoiding memorizing sets and prefers enumerations.

      Is this a result of his not knowing the method of loci as a means of travelling through sets and remembering them easily? It's certainly evidence he wasn't aware of the as a general technique.

      He does mention peg techniques, mind maps, and general mnemonic techniques.

    1. Until recently[30][31][32] there have been almost no attempts to compare the different theories and discuss them together.

      Relationship to the broader idea in Loewenstein as well...

    2. Autopoiesis is just one of several current theories of life, including the chemoton[20] of Tibor Gánti, the hypercycle of Manfred Eigen and Peter Schuster,[21] [22] [23] the (M,R) systems[24][25] of Robert Rosen, and the autocatalytic sets[26] of Stuart Kauffman, similar to an earlier proposal by Freeman Dyson.[27] All of these (including autopoiesis) found their original inspiration in Erwin Schrödinger's book What is Life?[28] but at first they appear to have little in common with one another, largely because the authors did not communicate with one another, and none of them made any reference in their principal publications to any of the other theories.

    1. Arrays are not sets. Trying to treat them as if they are is an error, and will create subtle problems. What should be the result of the following operations? [1, 1] | [1] [1] | [1, 1] Of course, there are more interesting examples. These two are to get you started. I don't care what the results currently are. I don't care what you think they should be. I can present extremely strong arguments for various answers. For this reason, I believe that #| is an ill-defined concept. Generalizing an ill-defined concept is a world of pain. If you insist on treating objects of one class as if they were members of a different class, there should be bumps in the road to at least warn you that maybe this is a bad idea. I'm not going to argue that we should remove or deprecate #|. I don't think of myself as a fanatic. But encouraging this sort of abuse of the type system just creates problems.

    1. remove aset.remove(item) Removes item from the set

      There's also .discard(item) which does the same as .remove(item) except for one thing. It does not raise an error if the item is nonexistent.

    2. Removes an arbitrary element from the set

      And returns that value

    1. Girls, even when their abilities in science equaled or excelled that of boys, often were likely to be better overall in reading comprehension

      What does this say about different skill sets? Is this biological or genetic, or is it just conditioned?
