DSA & Q-Lab: 'In an Age of Answers, Questions Matter More Than Ever'

This afternoon I joined an online webinar organised by THE DIGITAL STATECRAFT ACADEMY:

'Gaining understanding by structuring inquiry: 
probing data with one right question after another is almost here'

The art, science, and practice of governing well in the algorithmic age

The Digital Statecraft Academy (DSA) is a global hub for cultivating visionary public leaders ready to navigate the complexities of data, AI, and digital governance. Backed by world-leading academic and policy institutions, DSA equips today’s leaders with the tools, knowledge, connections, and foresight to govern ethically, strategically, and resiliently in a rapidly evolving digital world.
 
 
Also highlighted was Q-Lab 


About Q-Lab

Questions shape what becomes visible, what is investigated, what is funded, and ultimately what societies come to know. They are fundamental not only to scientific inquiry but to a wide range of sectors and practices—from education and journalism to policymaking, medicine, law, and business, among others.

Despite this foundational role, questions are seldom treated as objects of systematic study. Established fields examine intelligence, knowledge production, and decision-making, yet few, if any, take questions themselves as their subject.

How should we define a good question? Which questions are most likely to serve as stepping stones toward breakthrough insights? Who determines which questions matter most? In short, what do we actually know about questions?

Questions Lab (Q-Lab) is the first multidisciplinary initiative dedicated to establishing questions as a field of study and practice, understanding how questions emerge, how they evolve, which questions make the greatest impact, and how they shape the trajectory of knowledge across disciplines and generations, in order to help individuals and institutions navigate complexity, deliberate more thoughtfully, and set better priorities.


I look forward to more events in future.

Book review: 'Categories: A Study of a Concept in Western Philosophy and Political Thought'

Categories

 

To - Edinburgh University Press. 

Many thanks for this book -

O’Sullivan L. Categories: A Study of a Concept in Western Philosophy and Political Thought. Edinburgh University Press; 2024.

Requested in May, your response was quick. So, my apologies for the delay in picking this up. In mitigation, what I have been learning since, will help my reading of O'Sullivan's text.

As readers of W2tQ will have realised, there is a built in bias to my reading of any text. In short: It's all about the model. 

Categories was spotted in Foyles on a visit to London. It recommended itself instantly: title, Venn diagrams, sets and all.

A larger format paperback of 335 pages, the print quality, font and design match the values and usual care of the publisher. 

Given the subject, there are appropriately distinct indices of subjects and proper names.

At pages 2-3, I have already succumbed (my emphasis):

'As a result, there is widespread contemporary recognition that categories are both important and problematic. A non-exhaustive list of academic fields and disciplines in which issues to do with categories arise includes anthropology, critical theory, cultural studies, feminist studies, history, linguistics, philosophy, political science, political theory, post-colonial studies, post-modernism, post-humanism, psychoanalysis, psychology, rhetoric and sociology. It is clear, moreover, that this recognition reflects the situation in society at large. Popular authors articulate a pervasive feeling that "Things are in the wrong place. Religion is in the box where science used to be. Politics is on the shelf where you thought you left science the previous afternoon." Categorical worries have penetrated public as well as academic discourse.' pp.2-3.

But how did Luke O'Sullivan know? On page 3 having given us the informal uses of the word 'category':

'These, moreover, are only the informal uses; there are also formal, logical and mathematical, senses which we shall largely have to pass over.'13

For me it is a disappointment that the formal aspects will be passed over. It is also a relief. 

For a model that is situated, as far as nursing theory, and models of nursing/care were concerned in 1997-8; Hodges' model had been left on the shelf - gathering dust.

I recognised a slide from a Youtube video this past week, care of Cheng I think? I'll share soon.

More to follow.

Medicine - Mathematics & History

'We now come to the input of mathematics into medical history, and to the related questions of arithmetic and quantification, ratio and proportion, geometrical argument and diagrams, and probability. Mathematics (consisting in arithmetic, geometry, astrology and music) had an established place in the quadrivium of the medieval arts course; its application to medicine is demonstrated in such textbooks as the Articella, which include treatises on weights and measures, and in studies of proportion and ratio such as those of the medieval Oxford calculators which Italian doctors among others caused to be revived at the beginning of our period. In the sixteenth century, it was a vigorously debated subject; there is a well-documented discussion of the certainty of mathematics, concerning its status in respect to the logical adequacy of its proofs, in which some natural philosophers and doctors (notably Cardano) take part. It will come therefore as no surprise that it was prescribed for doctors by most Renaissance pedagogical writers;  this prescription is often specifically linked to Galen's geometrical (axiomatic) method whose operations are the constitution of objects from elements, the comparison of existing objects and their reduction into their constitutive elements.

Associated with mathematics are diagrams, that is, abstract quantified spatial representations. There is a modern debate about the contribution of technical innovations in illustration in the Renaissance (most notably perspective) to the scientific revolution: this is only relevant here insofar as some participants in this debate argue for the importance of diagrammatic symbolisation of mental abstractions above those, like perspective, which are still representations of the real world, and see the former as a step on the path to full algebraic notation of geometry. Not all Renaissance thinkers were persuaded of their usefulness: Argenterio describes the diagrams of Manardo and Akakia reproduced below as 'vain and false tables and figures'; but I shall argue here that they were related to the uptake of doctors from the arts course insofar as well-known logical diagrams reproduced above (4.3:3) were adapted by them for their own purposes.' pp.171-172.

Maclean, Ian. 2002. Chapter 5, Beyond logic: geometry, proportion, quantity. In Logic, Signs, and Nature in the Renaissance: The Case of Learned Medicine. Cambridge/New York: Cambridge University Press.

Related to ongoing reading, Maclean provides two (among several) historical illustrations (with apologies for the quality) on pp.174-175, the first is from the Wellcome Collection:

Dubois, Jacques, 1478-1555 (Boe͏̈, Jacques, Bois, J. d., Boë, J., del, Boë, J., Del Boë, J., DelBoe͏̈, J., . . . Sylvius/de Bois). (1548). Methodus sex librorum galeni in differentiis et causis morborum et symptomatum in tabellas sex ordine suo conjecta paulo fusius ne brevitas obscura lectorem remoretur & fallat. de signis omnibus medicis, hoc est salubribus, insalubribus, & neutris, commentarius / ... per jacobum sylvium ..Paris: Retrieved from https://www.proquest.com/books/methodus-sex-librorum-galeni-differentiis-et/docview/2090356749/se-2

Jacobus Sylvius, 1539

Which Maclean then translates / interprets (p.174):

Maclean. Figure 5.1, p.174.

'Manardo goes further, and causes and symptoms adapts the square of contraries to represent not only all the possible combinations of temperaments (combinations of cold and hot and wet and dry are cleverly excluded) but also inserts a mediate point to represent the absolutely temperate body: see fig. 5.2.
This adaptation of the square of contraries (which has precedents in the medieval period) shows the appropriation for their own use by doctors of the logical instruments at their disposal.

As we have seen, it is a feature of medical thinking to take into account many circumstantiae or variables, and, over time, the numbers of variables taken into consideration increases.' p.174-175.

Koln 75

The film Koln 75 was very enjoyable ...
'Brandes quit the music business a few years ago, after a very successful career. Why? "Digital formats were taking over the record industry, which was giving away entire repertoires to companies like Apple with a completely idiotic accounting system in the background, which would never, ever allow for the artists to get properly remunerated for their rights. The whole industry thought that digital would be the biggest portion of whipped cream on top of the cake that they would continue to be eating until the end of all time.'"

Instead, inspired by a 1993 study that found that listening to classical music-specifically Mozart-enhances spatial-temporal reasoning, and by Don Campbell's bestselling 1997 book The Mozart Effect: Tapping the Power of Music to Heal the Body, Strengthen the Mind, and Unlock the Creative Spirit. Brandes studied psychology at university and then, funded by the Austrian Ministry of Culture, established the Research Program for Music-Medicine at the Paracelsus Medical University in Salzburg. "Being a music producer, I dreamt about doing scientific research on the effect of music and trying to figure out what effects music has on us - cognitive, emotional, whatever," she says. "Since then I have developed a method to use music to help people with chronic depression."

'Oh Thomasina!' Such a drama in a diagram

Arcadia

Last evening I really enjoyed a performance of Tom Stoppard's Arcadia at the Duke of York's, or soon to be - The Tom Stoppard Theatre:

Act I, Scene 2  

'Septimus ... You should no more grieve for the rest than for a buckle lost from your first shoe, or for your lesson book which will be lost when you are old. We shed as we pick up, like travellers who must carry everything in their arms, and what we let fall will be picked up by those behind. The procession is very long and life is very short. We die on the march. But there is nothing outside the march so nothing can be lost to it. The missing plays of Sophocles will turn up piece by piece, or be written again in another language. Ancient cures for diseases will reveal themselves once more. Mathematical discoveries glimpsed and lost to view will have their time again. You do not suppose, my lady, that if all of Archimedes had been hiding in the great library of Alexandria, we would be at a loss for a corkscrew? ...'^ p.20.

 Act II, Scene 3

'Lady Croom We are intruding here - this will not do, Mr Hodge. Evidently, nothing is being learned. (To Noakes) Come along, sir! 

Thomasina Mr Noakes - bad news from Paris! 

Noakes Is it the Emperor Napoleon? 

Thomasina No. (She tears the page off her drawing block, with her "diagram" on it) It concerns your heat engine. Improve it as you will, you can never get out of it what you put in. It repays eleven pence in the shilling at most. The penny is for this author's thoughts. 

She gives the diagram to Septimus who looks at it.' p.74
...
Now Septimus retrieves his book from Thomasina. He turns the pages, and also continues to study Thomasina's diagram. ... 

Septimus Why does it mean Mr Noakes's engine pays eleven pence in the shilling? Where does he say it? 

Thomasina Nowhere. I noticed it by the way. I cannot remember now. 

Septimus Nor is he interested by determinism -------

Thomasina Oh... yes. Newton's equations go forwards and backwards, they do not care which way. But the heat equation cares very much, it goes only one way. That is the reason Mr Noakes's engine cannot give the power to drive Mr Noakes's engine. 

Septimus Everybody knows that. 

Thomasina Yes, Septimus, they know it about engines! 

Pause. He looks at his watch 

Septimus A quarter to twelve. For your essay this week, explicate your diagram. 

Thomasina I cannot. I do not know the mathematics. 

Septimus Without mathematics, then.' p.75.

June 4-5 'Ecologies of Care' - London, UK

With more to follow from RCN Congress, this morning I received the agenda for next month's conference 'Ecologies of Care'. I am speaking, first session on the Thursday, which is a good to know and see the broad range of presentations. 

The focus on attention, is helpful for a possible further event in October. In the meantime, the Call for Papers began:

Chancellor’s Hall, Senate House London

June 4 & 5, 2026

Keynote lecture by Professor Yves Citton

How do increasing demands on our attention influence what we know, and how we act, in response to climate change? Despite a strong scientific consensus that climate change is ongoing and anthropogenic, political and legal action remains fragmented. Ecologies of Care asks to what extent the environmental crisis is a crisis of attention. Speaking to the dynamics of the attention economy, Yves Citton notes that “the new scarcity is no longer to be situated on the side of material goods to be produced, but on the attention necessary to consume them.” The word ‘attention’ is etymologically linked to the notion of care, or that which one attends to. This relationship (of subject and object) is fundamentally collective, insofar as collective attentional regimes influence what each one of us pays attention to on a daily basis, and how we navigate the barrage of informational flows from popular media.

Terms such as "the Anthropocene" and "planetary boundaries" function both as scientific descriptors and attempts to provoke action commensurate to the urgency that scientists believe their research demonstrates. The recent decision not to formalize the Anthropocene as an official geological unit, for example, highlights growing unease concerning intensifying media attention directed at scientific expertise. Under conditions of increasing disparity between what we know, and how we act, in response to climate change, the role of scientific expertise plays an increasingly normative, and not only informative, function. Scientific expertise attempts to direct what we attend to, and consequently, how (or if) we care. This is a collective practice of narrating and internalizing mythologies, whereby informational flows draw attention to some thing that needs to be cared for: Earth, the planetary, capital, or each other.

v WCCS26: World Conference on Complex Systems 20-22nd April

Day 2 Tuesday 21st April (Revisiting) Keynote Speaker: Abderrazak El Albani - 
Emergence of Intercellular Cooperation: At the Origins of Eukaryotic Complexity
Session Chair: Khawla Tadist

This keynote was fasacinating. As I begin this post on the 100th birthday of Sir David Attenborough, who would have us all see life in the broadest terms, value life and diverse habits, and Earth as our collective and shared home.

Abderrazak El Albani explained the search for LUCA the last universal common ancestor - 3.8 billion years ago. Many dates in the emergence story of humanity, have been progressively pushed back. The first fire, art, languages, our co-habitation and intimate relationships with Neanderthals.

In healthcare, as a practitioner you have to be aware of your scope of practice. At WCCS, scale (as in iv) was ever present across research in complexity, and complex systems. Not just physical size nano-to-mega but temporal too, as we journeyed billions of years. Several of the slides are presented here:

https://www.synchrotron-soleil.fr/en/news/discovery-oldest-macroscopic-planktonic-eukaryotes-contribution-nanoscopium-beamline (with a reference).

There is a video (French): https://www.youtube.com/watch?v=bh3t26cU7xc

I asked a question, which may have been psychological preparation for own presentation to follow. Listening, I could see how the work Abderrazak El Albani and his team are doing, could be readily translated to the search for life on Mars. There has been a 'routine' interchange of planetary material between Earth and Mars over the aeons. Fitting surely that the sedimentary rocks sought lie in  A key lesson, is that light helps us see, but not all lights are equal. Light sources brighter than the sun become incredible scientific instruments. The longevity of the dinosaurs was highlighted, at least 140 million years. There is no comparison with homo sapiens then, even as those dates have been pushed further back in time. Time defeated me as I tried to make the observation that even the dinosaurs did not make it to their first galactic birthday (c.250 million years - and what a carousel). I like the thought (slide) of 'Earth as Memory'. 

What really counted was the expressed concern about what is happening now: in the Anthropocene.

The second keynote:
Nigel Gilbert - Policy in a Complex World: Towards Complexity-Aware Policymaking
Session Chair: Ali Idri 

Was helpful to me, as the dated conundrum of benefits realisation from our technologies, and evidence-based policy still leaves a gap (for me) within the POLITICAL care/knowledge domain of Hodges' model. The illustration/graphic elements of Prof. Gilbert's slides were a brilliant complement to the content:

Prof. Nigel Gilbert - WCCS26 21st April

I wonder if within policy the constant in the equation is continuity and as a quantity it is an unknown? This seems to the case in health policy, across successive governments. You may (also) find this chart informative: https://www.cecan.ac.uk/news/the-visual-representation-of-complexity/

Perhaps, a key factor in complexity is the fact that nothing stays the same, so continuity is nuanced? Michael Quinn Patton's book Developmental Evaluation was noted re. learning while doing. Now I wish I'd held on to Qualitative Research & Evaluation Methods (4th ed.). The discussion of 'obesity system map' and 'whole systems analysis' was appreciated here.*

Since Marrakech and WCCS, I've noticed acknowledgement in the literature that 'research' is currently flooded with AI tools. I'm sure PRSM - Participatory System Mapper is a welcome addition, (as noted in iv) tools to facilitate participation are much needed:

Collaborative Creativity

The Participatory System Mapper (PRSM) is an app that makes it easy to draw networks (or 'maps') of systems, working together collaboratively.'

I will definitely check this resource out; and CECAN. After Prof. Gilbert, the next Track included my contribution, which I will return to. Rather distracted, I have a somewhat blurred slide, with: 'The global tensor of educational research is' then headed 'Learning poverty. Being unable to read and understsand a simple text; with points 1-4.'. I'm not sure which presentation this was, but zeroed in on the literacy theme, and the word tensor. Another slide refers to '6. Topological substitution for Success'. I think it is (writing this is helping recall!):

Harvey Spencer Sánchez-Restrepo, Jorge Louçã, Martha Belén Carmona-Soto and Sofialeticia Morales-Garza
Topological Patterns of Academic Success: Insights from Complex Network Analysis

'Always Label Your Axes' - Zazzle.

Before that there was another model, as the next keynote speaker: Chris Bauch demonstrated during the conference wearing a t-shirt:

iv WCCS26: World Conference on Complex Systems 20-22nd April

Day 1: Panel 2 - Rethinking Knowledge in the Age of Complexity

  • Helena Knyazeva - Dancing with Complexity: How the World Thinks Through Us
  • Carlos Gershenson - The Implications of Complexity
  • Leonardo Rodríguez Zoya - Can Statistics Think? Complexity, Future, and Freedom in the Age of Large Language Models
    Panel Chair: Nigel Gilbert 

Courage is one of the 6Cs in nursing, and was on display at WCCS26.

Carlos Gershon began by offering two references, the first:

De Domenico, et al., (2019). Complexity explained: A grassroot collaborative initiative to create a set of essential concepts of complex systems. https://complexityexplained.github.io

This is a brief 20 pages, larger text, and provides a helpful primer to complexity and related concepts covering:

Interactions
Emergence 
Dynamics 
Self-organization
Adaptation
Interdisciplinarity
Methods

For each concept, the authors explain:

Definition/Description
Examples
Relevant Concepts
References

Plus, secondly:

Gershenson, C. The Implications of Interactions for Science and Philosophy. Found Sci 18, 781–790 (2013). https://doi.org/10.1007/s10699-012-9305-8

I liked the practical feel here, the encouragement to think anew, and perhaps taste the "flavors of emergence": synchronic - space; diachronic - time, weak and strong feedback, transversal of scale - upwards and downwards.

There is further conference on complexity later this year (and also online!):

CCS 2026:
The 2026 Conference on Complex Systems
OCTOBER 9 - 16, 2026 BINGHAMTON, NY, USA & ONLINE

In my search I also found:

Carlos Gershenson; Complexity, Artificial Life, and Artificial Intelligence. Artif Life 2025; 31 (3): 289–303. doi:https://doi.org/10.1162/artl_a_00462

Leonardo Rodríguez Zoya's presentation helpfully connected social practice, interdisciplinary bridges, statistical rationality, complex (human) rationality and the future(s): desirable, possible, latent and probable.

I missed the poster at the afternoon break, and followed track 1. I greatly enjoyed Julian Arevalo's - Adaptive Readiness: an Agent-Based Model of Peace Negotiations. Perhaps this accounts for my having no notes or photos for this track except for one.

The paper by Saida Hachimi El Idrissi and Mohamed Nemiche is not open access, but the abstract follows. 
 
S. H. El Idrissi and M. Nemiche, "Formation of Complex Societies: An Agent-Based Model Inspired by Freudian Theory," 2024 World Conference on Complex Systems (WCCS), Mohammedia, Morocco, 2024, pp.1-6, doi: 10.1109/WCCS62745.2024.10765573.
Abstract: The rise and emergence of complex societies in the Old World mark a pivotal chapter in human history, characterized by the transition from small, kin-based communities to large, hierarchical states. This transformation raises fundamental questions: How did human societies progress from small, cohesive groups characterized by face-to-face cooperation to the expansive, anonymous societies of today, often organized as states? What factors account for the significant variation in different human populations' capacity to construct stable and functional state structures? To address these questions, we developed an agent-based model grounded in Freud's hypothesis, which posits that civilization could neither emerge nor evolve without the repression of human desires. In the context of social evolution, this repression of desires can be interpreted as the repression of intra-societal competition, ultimately strengthening the society and facilitating the formation of complex social structures. We implemented this model within a realistic representation of the Afroeurasian landmass, incorporating various geographical factors. To validate our model, we compared our simulated results with historical data. The model-predicted pattern of expansion of complex societies demonstrated remarkable congruence with the observed historical patterns in the Old World. The emergence, growth, and distribution of large-scale societies predicted by our computational model showed remarkable consistency with the archaeological and historical record.

Unless you are a microsurgeon (increasingly with robotic co-workers), is the word practice, more likely to manifest what is larger, the big picture, a sense of space, even at a societal or continental scale? In reading, I came across four forms of attractors. For me, how they fit into the question of scale makes this paper worthy of seeking out. 

M. Nemiche was unable to attend the conference, and was greatly missed.

iii WCCS26: World Conference on Complex Systems 20-22nd April

Chaos
Making a New Science 
by James Gleick


When I first learned of WCCS26, I saw a connection, an affinity across the conference themes. This was reinforced when I read the final program for WCCS. Here was a home for the model, a way-point for Hodges' model. For an independent scholar, it was quite a trip to Ben Guerir, to the north of Marrakech; 13 hours (brief by global standards). It was a place to wave wildly, making use of the opportunity to present Hodges' model, to say - "Dear All, can you do anything with this?".


It is almost 40 years since I read James Gleik's, Chaos: Making a New Science. That was in Cornwall I think? Now, something more than book - a complexity conference.  

 After the first two keynotes - two panels: 

 Panel 1 - Complexity, Society & Global Challenges

▪ Carlos Álvarez Pereira - No Limits to Hope: Escaping from the unreasonable effectiveness of Modernity
▪ David Chavalarias - The Artificialization of Cultural Evolution: the Impact of Very Large Digital Infrastructures on Individuals and Society
▪ Louis Klein - Noospheric Singularity and the Mirror of Tamkeen
Panel Chair: Karima Kadaoui

These confirmed I was in the right place. Well, it was bit late if I wasn't! I was reminded of the slow movement, and how in healthcare, specifically client-nurse intereactions you had time to manage your time, that is your caseload to deliver person-centred care. I don't mean time-wasting, as in social chat, tea and custard creams either. This is what being professional is about, truly trying to make a difference - that lasts. So we worked through: What is; (science) what we understand; and (tech and law) what should be. Ecologically, we often refer to the size of our footprints. Panel one considered this individually and collectively - institutionally. Fascinating to reflect upon these themes and how modernity is stamping about in a rather chaotic way? We are seemingly power-less to stop this.

c/o Carlos Álvarez Pereira
No Limits to Hope: Escaping from the unreasonable effectiveness of Modernity

Three reports to the Club of Rome were displayed, spanning 'NO LIMITS TO LEARNING - Bridging the human gap' 1979; 'Limits and Beyond' 2022; 'NO LIMITS TO HOPE - Liberate the potential for Collective Learning' 2026. Should we be troubled, worried even, that the latest followed after a mere four years? There are of course, many reports as per the link above.

David Chavalarias - The Artificialization of Cultural Evolution: the Impact of Very Large Digital Infrastructures on Individuals and Society spoke about the beneficial and malign impacts of social media AI tools. Covid featured as might be expected. Within the sciences, what was worrying, was an innovation slowdown associated with AI, non-AI use, chartered around a central point (centroid). I believe the slide referred to:

Qianyue Hao & Fengli Xu & Yong Li & James Evans, 2026. "Artificial intelligence tools expand scientists’ impact but contract science’s focus," Nature, vol. 649(8099), pages 1237-1243, January. 

There was one slide:


Is this the demise of any efforts to achieve SOCIO-technical synergy? Even to the extent of realising benefits for the human in socio-technical systems? Did Covid not teach us anything about the informational difference technology can make? When so many technologies are muted by a virus? This is what we need: things to think about, question and critique. 

There used to be a series of A3 step-by-step oil painting magazines in the 1970s. One presented a desert campfire, clearly set in the east. I did try it, though not sure were the result is now. ... Such a scenario was presented by Louis Kleinand the Noospheric Singularity and the Tamkeen Process - Regenerative Hermeneutics, with the following reference provided:

Klein, L., & Kadaoui, K. (2024). Realising metamorphic transformation in the mirror of Tamkeen: Growing a shared understanding from co-reflected lived experiences. Systems Research and Behavioral Science, 41(5), 738–749. https://doi.org/10.1002/sres.3058 

There was much I could identify with. And, once again, I cannot continue at this pace. We have only covered (touched!) panel one. Hopefully you now have an idea of the depth of the conference programme. More however, will follow.

WCCS26: World Conference on Complex Systems 20-22nd April

It was good that today I could relax a little sooner than I expected with my presentation delivered over lunch time instead of 1730. To recap, at the 6th edition conference theme of:

“Navigating Contemporary Complexity:
Transdisciplinary Approaches to Economic, Social, Political, and Environmental Challenges”

- my talk (I added "Hodges' model" in the slides):

'Hodges’ model: PRESENTING a UNIVERSAL and SIMPLE CONCEPTUAL WORKBENCH to SITUATE and ENCOMPASS COMPLEXITY'

This after arriving back from a conference dinner near Marrakech at 0100, but the event at Chez Ali was different and most enjoyable. 

I'm conscious that unlike other speakers I (still!) did not have 'data' to share and discuss. Equations have been necessary over the first two days. But overall all sessions have proved accessible. From comments received Hodges' model was understood and deemed relevant. One delegate noted how the visual nature of Hodges' model was apparent, the illustrations revealed the model more clearly than a verbal description the evening before.

There were two questions. I eventually recalled awareness of Franco Basaglia, the Italian pioneer of community mental health and mental health law in Italy. Another questions concerned were I though the arts, drama and culture sit, or fit in Hodges' model? I suggested a search of the blog for posts tagged 'art', 'theatre', or 'culture'; with a warning that it can be a bit of a rabbit-hole.

Discussion, in-sessions and outside have proved refreshing, and not just as a welcome change from 'world news'. There were reminders too of early career researchers, professionals, and policymakers and the need to phone home.

While I pack for a transfer to Marrakech tomorrow afternoon, I will reflect and look to add more here.

In adition to data, I need new angles so I am not self-plagiarizing; hence the attempt to see Hodges' model as a mathematical object.

Many thanks to the WCCS26 Committee for being able to participate and share this model made in the 20th century for the challenges of the 21st.

More to follow and in the meantime, you can read the programme yourself.

'Our broken sticks' c/o Roger Lewin "Complexity: life at the edge of chaos"

Chapter 4 Explosions and Extinctions

  'Is Stu being led astray? I asked. "There's something called the broken stick model in statistics," said Dave. In this trick, a random number generator "breaks'' a stick a hundred inches long at twenty-five points, and produces twenty-six short sticks. Measure them, count the number that are one inch long, the number two inches long, and so on, and draw a histogram. You get a skewed distribution, toward the short end, just like many natural phenomena, including the distribution of sizes of U.S. cities, for instance. "One thing you have to remember about extinctions is that some species are more likely than others to die out, just because they exist as small, isolated populations,'' explained Dave. "This sort of statistical quirk can skew your results, easily." So, you would be suspicious of anything that looks like a power law? "I would, because it's common, just in the nature of statistics. It may tell you that a system is poised at a critical point, whatever that means, but it may not. In any case, when Stu says that the curve he gets from my data is close to a power law, he knows that there are many other mathematical models that could fit equally well."
  Clearly, there were many reasons to be cautious about drawing the conclusion that global ecosystems are poised at the edge of chaos, using just the extinction data.' p.80.
 
Hodges' model: Axes (structure) and Domains (content)

If we take the axes of Hodges' model, and break them at twenty-five points, I wonder what we end-up (or start) with?

Lavoisier: Math - Chemistry; Quantity, Quality, Principle ...

The philosophy of science, can not avoid being viewed historically, which leads us to learn how mathematics literally took hold, from physics, to chemistry and biology. The application of mathematics to chemistry provides many and ongoing insights:

'Curiously enough, Kant’s own student, Jeremias Benjamin Richter (1762-1807), would only a few years later disprove his professor with his PhD dissertation On the use of the mathematical method in chemistry (Richter 1789). It laid the groundwork for stoichiometry as an algebraic approach to chemistry, including what was later called the ‘law of constant proportion’ that John Dalton used for his atomism on chemical grounds (Richter 1792-3, Dalton 1808). Moreover, at the time of Kant’s writing, experimental philosophy was taking over most of the centers of European research to become the mainstream methodology of modern science, which would later denounce the ideal of a priori knowledge in science as ‘mere’ metaphysics. Although some philosophers of mathematical physics still adhere to that ideal today, Kant was a late partisan in the struggle for the methodological priority of mathematics in the study of nature as it was exemplified by the old field of ‘rational mechanics’. Yet, his view on science became marginalized as much as his verdict on chemistry, that it would be alien to mathematics, was refuted.'

The pitfalls presented and Schummer's 2.4 A methodological suggestion for defining mathematical chemistry are helpful.

Joachim Schummer. Why Mathematical Chemistry Cannot Copy Mathematical Physics and How to Avoid the Imminent Epistemological Pitfalls. HYLE--International Journal for Philosophy of Chemistry, Vol. 18, No.1 (2012). pp. 71-89. https://www.hyle.org/journal/issues/18-1/schummer.htm

Maths is filled with tragedy, but the personal manifestation in my lack of ability, pales to insignificance to the many scientific and human tragedies history reveals. Consider Galois, and Lavoisier:

‘Only a moment to cut off that head and a hundred years may not give us another like it,’ lamented the 18th-century French mathematician Joseph Louis Lagrange. The head in question had belonged to the French aristocrat and chemist Antoine Laurent Lavoisier, who was executed at the hands of French revolutionaries on 8 May 1794. Lavoisier’s ideas changed the face of chemistry. He is best remembered for overthrowing the phlogiston theory, but perhaps his greater and more lasting achievement was to impose order on the language and symbolism that have shaped the thoughts of chemists.'

Paul Board, The Aristocrat who revolutionised chemistry, New Scientist. May 7, 1994 (Volume 142, Issue 1924). https://www.newscientist.com/article/mg14219243-300/

In an essay in the Charles Coulston Gillispie's essay in the history of scientific ideas, Chapter VI. The Rationalization of Matter, describes how Lavoisier sought to develop an algebraic approach:

'But what is most interesting is Lavoisier's mode of representing these results, so correct in quantity, so wrong in principle. In order to sec what he was about, one has to follow him into some detail. It is obvious, he writes, that acidification of a metal involves many variables-heat, concentration, chemical affinities, etc. each of which is a force acting with characteristic energy. Therefrom results a problem complex and difficult of solution: [my emphasis]

"Better to exhibit the state of the question in this respect, and in order to show at a glance the result of what happens in metallic solutions, I have constructed formulas of a sort, which could at first be taken for algebraic formulas, but which have not the same object, and do not derive from the same principles . . ."'

Gillispie, Charles Coulston. The Edge of Objectivity: An Essay in the History of Scientific Ideas. Princeton, N.J.: Princeton University Press, 1960.

Gillispie quotes at length to demonstrate Lavoisier's approach*. There is a more accessible (for me, here) source in -

Please see page 6: 3. Chemical equilibrium conception: The law of mass action.

To close, there is reading and advice to be carried forward in:

Guillermo Restrepo & José L. Villaveces, "Mathematical Thinking in Chemistry". Special Issue: Chemistry and Mathematics, Part 1. HYLE--International Journal for Philosophy of Chemistry, Vol. 18, No.1 (2012). pp. 3-22. https://www.hyle.org/journal/issues/18-1/restrepo-villaveces.htm

Gillispie concludes his illustrated exploration of Lavoisier:

'Is this not the most tantalizing memoir in the history of chemistry, and in Lavoisier's the most appealing? Here alone, one gets a sense of modesty. He never claims for these expressions the dignity of algebra. "We are still very far from being able to introduce mathematical precision into chemistry, and I beg, therefore, that no one consider these formulas . . . as more than simple annotations, of which the object is to ease the labors of the mind." (But compare this disclaimer with what he says of algebra itself in the Method of Chemical Nomenclature: "Algebra is the analytical method par excellence: it was invented to facilitate the labors of the mind, to compress into a few lines what would take pages to discuss, and to lead, finally, in a more convenient prompt and certain manner to the solution of very complicated questions.")' p.245.
