The difference between what you work out using the Zettelkasten and the memory palace technique is that the memory palace is a pure memory technique. It uses meaningless connections [emphasis added] and the way the brain works to gain access to information. For example, if I mentally write the date Rome was founded with the mnemonic “BC 753 Rome came to be” as a number on an egg in the kitchen fridge, the only reason for this link between the egg in the kitchen fridge of my memory palace and the year Rome was founded is that I can remember this number.

Certainly not an attack against him, but I feel as if Sascha is making an analogistic reference to areas of mnemonics he's heard about, but hasn't actively practiced. As a result, some may come away with a misunderstanding of these practices. Even worse, they may be dissuaded from combining a more specific set of mnemonic practices with their zettelkasten practice which can provide them with even stronger memories of the ideas hiding within their zettelkasten.

There is a mistaken conflation of two different mnemonic techniques being described here. The memory palace portion associates information with well known locations which leverages our brains' ability to more easily remember places and things in them with relation to each other. There is nothing of meaningless connections here. The method works precisely because meaning is created and attributed to the association. It becomes a thing in a specific well known place to the user which provides the necessary association for our memory.

The second mnemonic technique at play is the separate, unmentioned, and misconstrued Major System (or possibly the related Person-Action-Object method) which associates the number with a visualizable object. While there is a seeming meaningless connection here, the underlying connection is all about meaning by design. The number is "translated" from something harder to remember into an object which is far easier to remember. This initial translation is more direct than one from a word in one language to another because it can be logically generated every time and thus gives a specific meaning to an otherwise more-difficult-to-remember number. As part of the practice this object is then given additional attributes (size, smell, taste, touch, etc., or ridiculous proportion or attributes like extreme violence or relationships to sex) which serve to make it even more memorable. Sascha seems break this more standard mnemonic practice by simply writing his number on the egg in the refrigerator rather than associate 753 with a more memorable object like a "golem" which might be incubating inside of my precious egg. As a result, the egg and 753 association IS meaningless to him, and I would posit will be incredibly more difficult for him to remember tomorrow much less next month. If we make the translation of 753 more visible in Sascha's process, we're more likely to see the meaning and the benefit of the mnemonic. (I can only guess that Sascha doesn't practice these techniques, so won't fault him for missing some steps, particularly given the ways in which the memory palace is viewed in the zeitgeist.)

To say that the number and the golem (here, the object which 753 was translated to—the Major System mnemonic portion) have no association is akin to saying that "zettlekasten" has no associated meaning to the words "slip box." In both translations the words/numbers are exactly the same thing. The second mnemonic is associating the golem to the egg in the refrigerator (the memory palace portion). I suspect that if you've been following along and imagining Andy Serkis gestating inside of an egg to become Golem who will go on to fight in the Roman Coliseum in your refrigerator, you're going to see Golem every time you reach for an egg in your refrigerator. Now if you've spent the ten minutes to learn the Major System to do the reverse translation, you'll think about the founding date of Rome every time you go to make an omelette. And if you haven't, then you'll just imagine the most pitiful gladiator loosing in the arena against a vicious tiger.

Naturally one can associate all their thoughts in their ZK to both the associated numbers and their home, work, or neighborhood environments so that they can mentally take their (analog or digital) zettlekasten with them anywhere they go. This is akin to what Thomas Aquinus and Raymond Llull were doing with their "knowledge management systems", though theirs may have had slightly simpler forms. Llull actually created a system which allowed him to more easily meditate on his stored memories and juxtapose them to create new ideas.

Summary - This is an extremely important paper with a startling conclusion of the magnitude of the social and economic impacts of the biodiversity disruption coming down the pipeline - It is likely that very few governments are prepared to adapt to these levels of ecosystemic disruption - Climate departure is defined as an index of the year when: - The projected mean climate of a given location moves to a state that is - continuously outside the bounds of historical variability - Climate departure is projected to happen regardless of how aggressive our climate mitigation pathway - The business-as-usual (BAU) scenario in the study is RCP85 and leads to a global climate departure mean of 2047 (+/- 14 years s.d.) while - The more aggressive RCP45 scenario (which we are currently far from) leads to a global climate departure mean of 2069 (+/- 18 years s.d.) - So regardless of how aggressive we mitigate, we cannot avoid climate departure. - What consequences will this have on economies around the world? How will we adapt? - The world is not prepared for the vast ecosystem changes, which will reshape our entire economy all around the globe.

• Title:Major Evolutionary Transitions and the Roles of Facilitation and Information in Ecosystem Transformations

• Author: Robin et al.

• Date: 2021

• Abstract

  • A small number of extraordinary “Major Evolutionary Transitions” (METs) have attracted attention among biologists.
  • They comprise novel forms of
    • individuality and
    • information,

  • and are defined in relation to organismal complexity, irrespective of broader ecosystem-level effects.

  • This divorce between

    • evolutionary and
    • ecological consequences

  • qualifies unicellular eukaryotes, for example, as a MET although they alone failed to significantly alter ecosystems.

  • Additionally, this definition excludes revolutionary innovations not fitting into either MET type

    • (e.g., photosynthesis).
  • We recombine
    • evolution with
    • ecology
  • to explore how and why entire ecosystems were
    • newly created or
    • radically altered

  • as Major System Transitions (MSTs).

  • In doing so, we highlight important morphological adaptations that spread through populations because of

    • their immediate, direct-fitness advantages for individuals.

  • These are Major Competitive Transitions, or MCTs.

  • We argue that often
    • multiple
      • METs and
      • MCTs

  • must be present to produce MSTs.

  • For example, sexually-reproducing, multicellular eukaryotes (METs) with

    • anisogamy and
    • exoskeletons (MCTs)

  • significantly altered ecosystems during the Cambrian.

  • Therefore, we introduce the concepts of Facilitating Evolutionary Transitions (FETs) and Catalysts as

    • key events or agents that are insufficient themselves to set a MST into motion,
    • but are essential parts of synergies that do.

  • We further elucidate the role of information in MSTs as transitions across five levels:

    • (I) Encoded (Genetic);
    • (II) Epigenomic;
    • (III) Learned;
    • (IV) Inscribed; and
    • (V) Dark Information.

  • The latter is ‘authored’ by abiotic entities rather than biological organisms.

  • Level

    • IV has arguably allowed humans to produce a MST, and
    • V perhaps makes us a FET for a future transition that melds
      • biotic and
      • abiotic life
    • into one entity.
  • Understanding the interactive processes involved in past major transitions will illuminate both
    • current events and
    • the surprising possibilities that abiotically-created information may produce.

first-century rabbi Eliezer ben Hyrcanus (Mishnah Avot 2:9) and alluded to what some termed on other occasions his ‘marvelous memory for detail’, ‘encyclopedic mind’, or ‘inexhaustible stores of memory’ that allowed him to furnish his ‘convincing array of facts’ 5 (Heller, 1916; L. F., 1919; Mendelsohn, 1916; Schulman, 1922; Stolz, 1921). However, it was perhaps not Deutsch himself who was a ‘cistern’ but instead his card catalogue where he stored drops of data growing to a sea of erudition and which served as a prosthesis for his legendary recall (see Figure 1).

While the practice with his zettelkasten may have been helpful, it's quite likely that given these quotes about his memory that they're evidence of the use of the major system which would have been quite popular and well known at his time, but which isn't now.

The author is going to need to provide evidence one way or another, but I suspect they're not aware of the mnemonic traditions of the time to make the opposite case.

Given the late 1880's time and German and US locations, it's quite likely that Gotthard Deutsch practiced mnemonics and in particular the major mnemonic system.

This quote is tangential evidence of this.

Carl Otto Reventlow (1817-1873) and the history of the Major System

I was delving into the history of mnemonic techniques earlier hunting down some of the origins of the major system and ran across a reference to Reventlow from the late-1800s. He apparently borrowed much of his work from Aime Paris, but helped to popularize a variation of the method in Germany and Prague.

A sketch with some great references (in German) was already hiding on Wikipedia: https://en.wikipedia.org/wiki/Carl_Otto_Reventlow

Bonus points for anyone who can track down a digital edition of his 1843 textbook.

Karl Christian Otto (aka Carl Otto Reventlow) published a textbook on a mnemonic system in 1843 and then travelled to publicize and popularize it including notable lectures in Leipzig and Prague. His system, likely broadly similar to the major system, may have been take from Aimé Paris' method.

Sources indicate that it was borrowed from Paris, but it received favorable reviews.

Source used by Edward Pick for some of his history of memory.

Mnemonics for the places or pictures used by his predecessors. The historians of Mnemonics, especially Aretin, Reventlow, and the learned and famous bibliographer, Edward Marie Oettinger, in Leipzic, to whom I owe the above-mentioned and some of the following details on the history of Mnemonics, give a dozen other names of authors on Mnemonics belonging to this epoch.*

Edward Pick mentions Conrad Celtes in passing for having "made the great discovery that the alphabet could be substituted in Mnemonics for the places and pictures used by his predecessors. He doesn't provide a textual source for the information.

Pick indicates that his primary sources were Edward Marie Oettinger, (Johann Christoph Freiherr von) Aretin, and (Carl Otto) Reventlow who may have more detail on Celte's potential influence on the major system as well as potential alternate names from that era.

Second Transition: Columbian Exchange

In evolutionary biology, there are also another type of transition, Major Evolutionary Transitions (MET). Robin et. al propose that the introduction of writing (inscribed language) was a major information improvement that played an important role leading to a major system transition (MST).

Major Evolutionary Transitions and the Roles of Facilitation and Information in Ecosystem Transformations https://hyp.is/go?url=https%3A%2F%2Fwww.frontiersin.org%2Farticles%2F10.3389%2Ffevo.2021.711556%2Ffull&group=world https://hyp.is/go?url=http%3A%2F%2Fdocdrop.org%2Fvideo%2F6J-J72GoqhY%2F&group=world

This can be interpreted as an instantiation of the hero's journey, in the context of research that combines evolution with ecology as in the research paper: Major Evolutionary Transitions and the Roles of Facilitation and Information in Ecosystem Transformations (Robin et al., 2021).From this lens, cumulative cultural evolution (CCE) was first made possible through spoken language, then accelerated through written language. The authors claim that another Major System Transition (MST).is emerging, which they posit to be abiotic in nature involving Artificial Intelligence.

Faced with a self-induced civilization-scale threat, we may ask whether a major cultural evolution may be necessary to avoid catastrophe and whether it may constitute another MST. Could a rapid higher level global understanding of the epistemological dualism of self and other which undergirds normative alienation, othering and conflict, both with others of our own species, of other species and with the planetary system itself play a major role in the transition?

I was sort of hoping that there would be a more linguistic structured correspondence between the alphabet and numbers as a potential precursor of the phonetic major system, but alas no.

Within this human body, we embed 4 different stages of Major Evolutionary Transitions (MET).

Our human body is the product of billions of years of evolution, embodying various outputs from each major stage of a Major Evolutionary Transition (MET). We are a multi-cellular being, a colony. Yet,at the same time, we have living elements that at one time in history, were independent living beings which were NOT part of a multi-cellular colony!

In the deep history of the evolution of the human body, genes, mitochondria, eukaryotes were all once autonomous living entities, each a biological self with its own boundary separating inner from outer. Virus's helped to catalyze their mutualism over deep time.

Now, over billions of years of evolution, they are all integrated together by the extra-cellular matrix and laminin protein into our multi-cellular human body, replicating as one super, super, super organism.

Finally, inscribed language has allowed us to undergo another kind of transition, a major system transition (MST) where human beings now dominate the entire biosphere, for better and for worse.

This is the key to Major Evolutionary Transition - a population of free living individual creatures discover that in teaming up, there is a greater resultant evolutionary fitness, mutualism symbiotic relationship emerges. It becomes so strong over time that the many become a self-replicating one.

The biological self is always defined by a boundary between inner and outer, but in this act of mutualism, the many biological selves join to form a new higher order biological self.

In this way, a multi-cellular species like ours is somewhat like one of those nested Russian dolls.

Indeed, Amanda Robins hypothesizes

https://hyp.is/NyrixELGEeyYWN_d76UNMg/docdrop.org/video/6J-J72GoqhY/

that our species has undergone what she and Peter Nonacs calls Major System Transition (MST). The cultural artifact of inscribed language has made possible a superorganism / supraorganism that has spread across the globe.

Robin argues that spoken language alone, while a MET does not constitute a MST because spoken language could not have resulted in the global spread of ideas that made our current globalized modernity possible. However, it is a Facilitating Evolutionary Transition (FET) which paved the way for inscribed language which did enable the global spread of technology.

The transition from competing individuals to a coherent unity is a fascinating journey.

Applied to human society at a time of the Anthropocene, these principles of evolutionary biology may be salient to apply to the superorganism/supra-organism of humanity undergoing a process of rapid whole system change.

The Palette of Being is a very useful idea that is related to Cumulative Cultural Evolution (CCE) and autopoiesis. From CCE, humans are able to pass on new ideas from one generation to the next, made possible by the tool of inscribed language.

Peter Nonacs group at UCLA as well as Stuart West at Oxford research Major Evolutionary Transitions (MET) West elucidates that modern hominids integrate the remnants of four major stages of MET that have occurred over deep time. Amanda Robins, a researcher in Nonacs group posits the idea that our species of modern hominids are undergoing a Major Systems Transition (MST), due specifically to our development of inscribed language.

CCE emerges new technologies that shape our human environments in time frames far faster than biological evolutionary timeframes. New human experiences are created which have never been exposed to human brains before, which feedback to affect our biological evolution as well in the process of gene-culture coevolution (GCC), also known as Dual Inheritance theory. In this way, CCE and GCC are entangled. "Gene–culture coevolution is the application of niche-construction reasoning to the human species, recognizing that both genes and culture are subject to similar dynamics, and human society is a cultural construction that provides the environment for fitness-enhancing genetic changes in individuals. The resulting social system is a complex dynamic nonlinear system. " (https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3048999/)

This metaphor of experiences constituting different colors on a Palette of Being is a powerful one that can contextualize human experiences from a deep time framework. One could argue that language usage automatically forces us into an anthropomorphic lens, for sophisticated language usage at the level of humans appears to be unique amongst our species. Within that constraint, the Palette of Being still provides us with a less myopic, less immediate and arguably less anthropomorphic view of human experience. It is philosophically problematic, however, in the sense that we can speculate about nonhuman modalities of being but never truly experience them. Philosopher Thomas Nagel wrote his classic paper "What it's like to be a bat" to illustrate this problem of experiencing the other. (https://warwick.ac.uk/fac/cross_fac/iatl/study/ugmodules/humananimalstudies/lectures/32/nagel_bat.pdf)

We can also leverage the Palette of Being in education. Deep Humanity (DH) BEing Journeys are a new kind of experiential, participatory contemplative practice and teaching tool designed to deepen our appreciation of what it is to be human. The polycrisis of the Anthropocene, especially the self-induced climate crisis and the Covid-19 pandemic have precipitated the erosion of stable social norms and reference frames, inducing another crisis, a meaning crisis. In this context, a re-education of embodied philosophy is seen as urgent to make sense of a radically shifting human reality.

Different human experiences presented as different colors of the Palette of Being situate our crisis in a larger context. One important Deep Humanity BEing journey that can help contextualize and make sense of our experiences is language. Once upon a time, language did not exist. As it gradually emerged, this color came to be added to our Palette of Being, and shaped the normative experiences of humanity in profound ways. It is the case that such profound shifts, lost over deep time come to be taken for granted by modern conspecifics. When such particular colors of the Palette of Being are not situated in deep time, and crisis ensues, that loss of contextualizing and situatedness can be quite disruptive, de-centering, confusing and alienating.

Being aware of the colors in the Palette can help us shed light on the amazing aspects that culture has invisibly transmitted to us, helping us not take them for granted, and re-establish a sense of awe about our lives as human beings.

Ann Blair indicates that stenography was only developed for German in 1834.

Is there a reference for this? When was it developed for other languages? How does this fit in with the timeline for memory and the major system?

I'd start with the basics of 0-9 of the Major System and then introduce the method of loci. Once they've got those two basics down reasonably I'd expand their Major system up to 99 at a minimum.

The tougher part then is expanding your pedagogy to build these tools into the curriculum so that you're actively using them with your content.

You might appreciate the experience from Lynne Kelly here: https://www.lynnekelly.com.au/?p=4794. Her excellent book Memory Craft also has some interesting examples and stories for children including the use of what she calls rapscallions for use in multiplication tables, languages, and other educational applications. Her book also has a wealth of other methods and potential applications depending on the subjects you're teaching.

I'd love to hear your experiences as you progress with your class.

I would question this statement, as annotated separately in this article. I have a feeling that the mnemonic tradition into the 1800's was more heavily influenced by the rise of the idea of the major system and not so much by the memory palace or the method of loci. This definitely seems to be the case in the United States based on my readings.

What relation does Henry Herdson's The Art of Memory Made Plaine (1651, 1654) have to the potential development of the major system. The description here sounds like it's relatively similar. Who/What were his precursors, and who may have been influenced by his version of this system which sounds very similar.

John Willis's Mnemonica (Latin 1618, English 1621, 1654, and 1661) covers memory, but he was apparently more interested in shorthand writing and also wrote Art of Stenographie.

I'll have to read this for a view into the overlap of memory and shorthand with respect to the development of the major system. Did this influence others in the chain of history? It definitely fits into the right timeline.

In looking at this, I immediately wonder about the nature of the treatises. I would suspect there's a slow decline of treatises on the method of loci while the 1800's sees an increase of those writing about the major system and which I've found generally aren't aware of the method of loci or earlier methods.

Were students asked or told if they'd be tested with this on long-term memory?

Personally, I'd have used a simple major system method to memorize such a list for short term memory, but would have used other techniques for long term memory.

Interesting that this links the idea of universal languages to his mathematical notation and NOT to the idea of translating numbers into words using and early form of the major system.

Sadly no reference to which book or portion in which this segment appears.

Read chapter 11 "Memorizing Number" to see what Gardner says about available techniques. He only covers the phoenetic major system and some basic associative techniques.

No mention of the method of loci. Some interesting references listed for the chapter however.

Lewis Carroll aka Dodgson never published his own version of his memory system.

N.B. He indicates here that he filled in his vowels ad libitum which is now the common practice for the phonetic major system. As this indicates he never published it, it then becomes a question as to whether or not he was the originator of this part of the technique or if it was later re-invented/discovered by others.

Apparently the beginning of the phonetic major system? Was there any relation to Celtes?

Here he's interestingly removed the vowels, which is certainly reminiscent of the later Major System structure in at least some respect.

This seems to be very common practice in the modern art as many writers suggest using or modifying techniques so that they suit your experience and lived memory. If a different key word comes to you more quickly, then why not use that instead of one supplied by the creator of the system.

There's also an echoing of this in Beniowski's idea of notions in "A Handbook of Phrenotypics" on the closeness of ideas.

This may provide some additional proof that it's a memory aid in the potential form of a notebook or commonplace book. What were the likelihoods of these being more common that other books/texts? What other codes were used at the time? Was the major system or a variant in use at the time?
